    ABSTRACT Aim Trait variation across geographic gradients can reveal how species respond to different environmental settings, which is crucial under the growing threat of climate change. Although on the basis of evolutionary theory, the patterns and drivers of intraspecific functional variation remain largely underexplored. In ants, pilosity and body size are morphological traits associated to thermoregulation and heat tolerance, which are critical concerns in the context of global warming. Here, we focused on the dominant ant Camponotus crassus to investigate trait variation and its potential drivers across a latitudinal gradient in the Brazilian Cerrado savanna. Location Brazilian Cerrado savanna. Taxon Camponotus crassus Mayr, 1862 (Hymenoptera: Formicidae). Methods We measured mesosoma pilosity and body size of C. crassus across multiple sites, and evaluated their relationship with temperature, rainfall, solar radiation, vegetation and sugar‐rich resource variables. We also assessed morphological and genetic covariation to search for possible phenotypic plasticity or adaptation in C. crassus. Results Only sugar‐rich resources were found to significantly influence C. crassus pilosity. Specifically, a negative relationship between ant pilosity and sugar‐rich resources (i.e., proportion of plants with extrafloral nectaries and hemipteran trophobionts) was found. No covariation between pilosity and genetic dissimilarities was observed, suggesting phenotypic plasticity. None of the variables were significant to predict body size, while this trait positively covaried with genetics. Main Conclusions Our findings suggest resource availability as a critical factor for species thermoregulation under environmental change, a hypothesis previously reported in the literature. We emphasise the importance of examining intraspecific variation and phenotypic plasticity across large geographic scales, particularly under the scenario of rapid global change and the current threat to Cerrado savanna. Our work covers a still poorly investigated aspect of intraspecific variation of tropical eusocial insects, and sheds new light on trait variation associated with large geographical gradients and resource availability in a major ecosystem.

    ABSTRACT The genus Camellia is widely distributed, primarily in East Asia. Camellia japonica is located at the northern limit of this genus distribution, and understanding changes in its distribution is crucial for understanding the evolution of plants in this region, as well as their relationship with geological history and climate change. Moreover, the classification of sect. Camellia in Japan has not been clarified. Therefore, this study aims to understand the evolutionary history of the Japanese sect. Camellia. The genetic population structure was analysed using SNP data and MIG‐seq. The relationship between the Japanese sect. Camellia, including the related species in China, was further inferred from the phylogeny generated by RA x ML, SplitsTree and PCA. Population genetic structure was inferred using a Bayesian clustering method (ADMIXTURE). We subsequently employed approximate Bayesian computation, which was further supported by the coalescent simulations (DIYABC, fastsimcoal and Bayesian Skyline Plots) to explore the changes in population, determining which events appropriately explain the phylogeographical signature. Ecological niche modelling was combined with genetic analyses to compare current and past distributions. The analyses consistently showed that C. japonica and C. rusticana are distinct, having diverged from each other during the Middle to Late Miocene period. Furthermore, C. japonica differentiated into four major populations (North, South, Ryukyu‐Taiwan and Continent). The Japanese sect. Camellia underwent speciation during archipelago formation, reflecting its ancient evolutionary history compared with other native Japanese plants. C. rusticana did not diverge from C. japonica in snow‐rich environments during the Quaternary period. Our results suggest that both species have been independent since ancient times and that ancestral populations of C. japonica have persisted in northern regions. Furthermore, the C. japonica population on the continent is hypothesised to have experienced a reverse‐colonisation event from southern Japan during the late Pleistocene glaciation.

    <jats:title>Abstract</jats:title><jats:p>The Ogasawara Islands, one of the UNESCO World Natural Heritage Site located about 1000 km south of Japan’s main island, harbor numerous endemic species, many of which are as endangered. One of the endemic plant species, <jats:italic>Lobelia boninensis</jats:italic>, found in the Mukojima, Chichijima, and Hahajima archipelagoes, is endangered due to predation. As part of conservation efforts, translocation is now underway, especially on Chichijima. However, we lack essential information, such as the genetic population structure, to develop appropriate translocation strategies for both wild and planted individuals. Here, we aimed to identify the conservation units and the origin of planted individuals by estimating the genetic population structure and phylogenetic relationships across all habitats of this species. We identified two distinct genetic clusters, indicating genetic differentiation between the northern and southern populations. The genetic population components detected at an isolated site on Chichijima showed a mixture of these distinct clusters, probably due to hybridization. The transplanted individuals in Chichijima were found to have originated from a population in Hahajima. These results suggest the presence of two distinct conservation units. Furthermore, the current translocation strategy poses a risk of genetic contamination between these units, highlighting the need for revised conservation management practices.</jats:p>

    The evaluation of genetic diversity is important for the conservation of species. However, changes in genetic diversity during conservation are complex processes that depend on the characteristics of the species and environment. To evaluate the changes in genetic diversity from decline to recovery, we surveyed the coastal herb Calystegia soldanella in areas with varying degrees of non‐coastal plant invasion. First, to evaluate genetic diversity before the conservation measures, the spatial clonal structure of adults was investigated in a population invaded by non‐coastal plants. Second, to evaluate genetic diversity after the conservation measures, the regenerated individuals were investigated in the restoration plot. Moreover, to predict future genetic diversity without conservation measures, the effects of non‐coastal plant invasion on the production and genetic diversity of seeds were investigated using individuals from areas with various levels of non‐coastal plant invasion. In the adult population, 16 genets were identified in an 80 m × 4 m area. The maximum genet size was 30.3 m, suggesting the importance of clonal reproduction for population maintenance. In the restoration plots comprising 10 m × 10 m × 3 replicates, many seedlings (1.14 ramets/m2) emerged, resulting in high clonal diversity compared to that of the adult population. Therefore, the biomass and genetic diversity were rapidly restored at the beginning of the conservation practice. Non‐coastal plant invasion did not affect the genetic diversity of the seeds. However, it significantly reduced seed production. This suggests that non‐coastal plant invasion reduces sexual reproduction, resulting in the long‐term loss of genetic diversity.

    Abstract Reproductive interference, an interspecific interaction in reproductive process that exerts an adverse effect, has gained attention as a contributing factor in promoting exclusive distributions between closely related species. However, detailed studies on the possibility of reproductive interference between native plants are still lacking, presumably because strong reproductive interference can rapidly realize exclusive distributions, leaving the two species apparently independent. Salvia japonica and S. lutescens are found in separate localities at a small scale, although their distributions overlap at a large scale. We investigated the possibility of reproductive interference between them through field surveys, hand-pollination experiments, evaluation of hybrid fertility, cpDNA and nrDNA genotyping, and genome-wide DNA analysis. The field survey results did not reveal apparent negative interaction in competition for pollinator services. Mixed pollination with conspecific pollen and counterpart pollen reduced seed set in S. japonica, and hybrid progeny produced by mixed pollination were less than 20% as fertile compared to the pure species. The DNA genotyping results suggested the possibility of hybridization where their distributions overlap, and the genome-wide DNA analysis results showed clear genetic differentiation between the two species as well as the existence of hybrids. These results suggest that bi-directional reproductive interference between S. japonica and S. lutescens may have led to their present separated distributions at a small scale.

    How frequently hybridisation and gene flow occur in the contact zones of diverging taxa is important for understanding the speciation process. Stigmaeopsis sabelisi and Stigmaeopsis miscanthi high-aggression form (hereafter, S. miscanthi HG) are haplodiploid, social spider mites that infest the Chinese silver grass, Miscanthus sinensis. These two species are closely related and parapatrically distributed in Japan. In mountainous areas, S. sabelisi and S. miscanthi HG are often found in the highlands and lowlands, respectively, suggesting that they are in contact at intermediate altitudes. It is estimated that they diverged from their common ancestors distributed in subtropical regions (south of Japan) during the last glacial period, expanded their distribution into the Japanese Archipelago, and came to have such a parapatric distribution (secondary contact). As their reproductive isolation is strong but incomplete, hybridisation and genetic introgression are expected at their distributional boundaries. In this study, we investigated their spatial distribution patterns along the elevation on Mt. Amagi using male morphological differences, and investigated their hybridisation status using single-nucleotide polymorphisms by MIG-seq. We found their contact zone at altitudes of 150-430&#x2009;m, suggesting that their contact zone is prevalent in the parapatric area, which is in line with a previous study. Interspecific mating was predicted based on the sex ratio in the contact zone. No obvious hybrids were found, but genetic introgression was detected although it was extremely low.

    <jats:title>Abstract</jats:title><jats:p>The Ogasawara Islands, isolated from the continent throughout their geological history, harbor abundant endemic species. However, 32% of the native plant species are on the Japanese Red List, signaling their endangered status. Among these endangered species, <jats:italic>Calanthe hoshii</jats:italic> stands out as highly susceptible to extinction. Two wild and 89 ex situ individuals were alive in 2020, but the last known wild individual died in October 2021, indicating this species may have become extinct in the wild. Despite the conservation efforts under the Act for the Conservation of Endangered Species of Wild Fauna and Flora, the lack of essential information regarding genetic diversity and population structure among the remaining individuals poses a significant obstacle to developing effective conservation measures. In this research, we conducted a genetic analysis of the wild and ex situ individuals, which revealed notably reduced genetic diversity between individuals, with individual heterozygosity levels (1.0 × 10<jats:sup>−5</jats:sup>) measuring one‐ninth of those observed within a closely related species <jats:italic>Calanthe triplicata</jats:italic> (1.5 × 10<jats:sup>−4</jats:sup>). Comprehensive genetic analysis revealed that <jats:italic>C. hoshii</jats:italic> consisted of three genetic clusters of different sizes: cluster 1 comprised 95% of the total population, while clusters 2 and 3, with few individuals, were only found in the ex situ populations at Koishikawa Botanical Garden. Since extant <jats:italic>C. hoshii</jats:italic> maintains a remarkably low genetic diversity at both individual and population levels, it is necessary to consider future management strategies, such as artificial breeding among different clades identified in this study, to safeguard the stability and resilience of this species.</jats:p>

    Abstract Wild relatives of cultivars are crucial sources of genetic variation for further enhancement, yet they face potential threats due to contemporary environmental changes. Iris ensata var. spontanea, a wild progenitor of the Japanese iris cultivars (I. ensata var. ensata), is extensively cultivated in Japanese gardens, is distributed across mesic meadows and wetlands in Japan and East Asia. This species is currently threatened owing to habitat loss linked to land use alterations. We assessed genetic diversity and phylogenetic relationships in 32 wild accessions and the 14 principal Edo Group of Japanese iris cultivars, originally bred during the Edo period (1600–1868). In the phylogenetic tree, the cultivars formed a cluster with reduced inbreeding coefficients, suggesting a singular origin and interbreeding between the genetically distinct accessions. Conversely, wild accessions exhibited greater overall genetic diversity and higher inbreeding coefficients than cultivars, indicating frequent inbreeding within divergent natural populations. Our findings highlight the distinct genetic reservoirs of both wild accessions and Edo cultivars, although the former may face inbreeding challenges. Urgent conservation action is needed to ensure the genetic diversity of wild populations as natural resources.

    Abstract Adaptive introgression plays a vital role in allowing recipient species to adapt and colonize new environments. However, our understanding of such environment-dependent introgressions is primarily limited to specific plant taxa in particular settings. In Japan, two related orchid species, the autonomously self-pollinating Pogonia minor and the outcrossing Pogonia japonica, typically inhabit dry grasslands and wetlands, respectively. Intriguingly, an island ecotype of P. japonica exists in arid, wind-swept, open sites on volcanic mountain slopes on Kozu Island, in the oceanic Izu Islands. To investigate potential introgression and its implications between P. japonica and P. minor on Kozu Island, we applied a comprehensive approach that included examining morphological traits, genome-wide SNP data, and plastid DNA sequences. We also examined the breeding systems of these species on Kozu Island through artificial pollination experiments to determine if introgression from P. minor has endowed the P. japonica ecotype with selfing capabilities. Extensive sampling on Kozu Island revealed that all P. japonica specimens exhibit signs of introgression from P. minor, suggesting the absence of pure P. japonica populations on the island. Furthermore, the chloroplast haplotypes of the insular P. japonica ecotype consistently match those of P. minor, indicating a predominantly asymmetrical initial hybridization with P. minor acting mainly as the maternal parent in the formation of F1 hybrids. Despite the advantages of self-fertilization in isolated environments, the insular P. japonica does not exhibit autogamy. Consequently, the scarcity of moist habitats, rather than selection pressure for selfing, likely contributes to the observed widespread introgression. Our study strongly suggests that the arid-environment-adapted P. minor has introgressed into the insular ecotype of P. japonica, enabling its successful colonization of arid volcanic mountain slopes of the oceanic island.

    Abstract Hydrangea sect. Macrophyllae comprises deciduous shrubs including two species with seven infraspecific taxa distributed throughout the Japanese Archipelago and adjacent areas. In this study, we revealed a phylogeny of Hydrangea sect. Macrophyllae by using a larger dataset of genome-wide SNPs than those employed in a previous study and by adding more comprehensive taxa/populations, which cover the entire distribution of the section. We then revised the taxonomic treatment of sect. Macrophyllae based on the higher-resolution phylogenetic trees obtained in this study. The phylogenetic trees estimated in this study showed five major clades, suggesting that H. serrata var. minamitanii and var. yesoensis should be treated as independent species from other H. serrata, that H. serrata var. australis and var. yakushimensis could be subclassified under the major clades and that var. angustata could be a synonym of var. serrata. The divergence time of these major clades was estimated to be in the Pleistocene.

    During our investigation of the genetic and morphological variation within the distribution range of Paepalanthus calvus, we observed that specimens from Juiz de Fora municipality, Minas Gerais (Brazil) were morphologically divergent. Through genome-wide analyses using MIG-seq and detailed morphological comparisons, we were able to establish consistent differences between P. calvus and the Juiz de Fora specimens, which supported the recognition of a new species, Paepalanthus salimenae sp. nov. This new species is primarily distinguished by the narrow leaves; trichomes on the leaves, spathes, and scapes; densely pilose involucral bracts; and the tufted apex of some floral organs. Paepalanthus salimenae exhibits low genetic diversity and strong population structure. A preliminary conservation risk assessment suggests this species as Critically Endangered, highlighting the urgent need for conservation efforts to protect its habitat and intraspecific diversity. We provide photographs, line drawings and additional commentaries on the distribution, habitat, and morphological affinities of P. salimenae to congeneric taxa.

    Insects are one of the most diverse eukaryotic groups on the planet, with one million or more species present, including those yet undescribed. The DNA barcoding system has been developed, which has aided in the identification of cryptic species and undescribed species. The mitochondrial cytochrome c oxidase I region (mtDNA COI) has been utilised for the barcoding analysis of insect taxa. Thereafter, next-generation sequencing (NGS) technology has been developed, allowing for rapid acquisition of massive amounts of sequence data for genetic analyses. Although NGS-based PCR primers designed to amplify the mtDNA COI region have been developed, their target regions were only a part of COI region and/or there were taxonomic bias for PCR amplification. As the mtDNA COI region is a traditional DNA marker for the DNA barcoding system, modified primers for this region would greatly contribute to taxonomic studies. In this study, we redesigned previously developed PCR primer sets that targetted the mtDNA COI barcoding region to improve amplification efficiency and to enable us to conduct sequencing analysis on NGS. As a result, the redesigned primer sets achieved a high success rate (&amp;gt; 85%) for species examined in this study, covering four insect orders (Coleoptera, Lepidoptera, Orthoptera and Odonata). Thus, by combining the primers with developed primer sets for 12S or 16S rRNA regions, we can conduct more detailed taxonomic, phylogeographic and conservation genetic studies using NGS.

    The Calypsoinae orchid genus Dactylostalix, previously considered a monotypic genus endemic to Japan and the Russian Far East (the Kuril Islands and Sakhalin Island), is now redefined to encompass two species. This reclassification is based not only on the examination of type specimens and literature but also on molecular data. While Pergamena uniflora has long been regarded as a synonym of Dactylostalix ringens, it is distinguishable by its shorter scape, smaller flower, less spotted tepals, drooping sepals and lateral petals, labellum with smaller, narrowly triangular to ovate lateral lobes, more distinct keels on the adaxial surface of the lip, and a slender column with a smaller stigma and weakly developed clinandrium. We propose the new combination Dactylostalix uniflora, recognizing it as a distinct species within the genus Dactylostalix. Phylogenetic analysis utilizing genome-wide markers has also demonstrated that the two species are genetically distinct. Our findings, obtained through the integration of morphological data and molecular phylogenetics, indicate that D. uniflora represents a distinct evolutionary lineage from D. ringens. Examination of type specimens has led us to conclude that Calypso japonica, Dactylostalix maculosa, and Dactylostalix ringens f. punctatus are junior synonyms of D. ringens. Additionally, we designate the lectotypes for P. uniflora (= D. uniflora), C. japonica, and D. maculosa.

    Abstract Anthropogenic activities have reduced ecotones between the ocean and land, which is likely to threaten the population of brackish‐water brachyuran crabs. To assess the current status of these crabs, we examine the population genetic structures of three semi‐terrestrial brachyuran crabs widely distributed along the coast of the Japan and to clarify factors determining their genetic structures. We collected 184 Orisarma dehaani, 252 Chiromantes haematocheir, and 151 Helice tridens crabs from 36 localities of the Japanese archipelago. Genome‐wide SNP data from these crabs were analyzed using MIG‐seq. Bayesian clustering of STRUCTURE and DAPC analysis were used to identify genetically disturbed populations and to visualize genetic differentiation between local populations. Genetic population structure showed clear differentiation between populations on the Pacific coast of the Tohoku region and on other Japanese coasts in O. dehaani, but not in C. haematocheir or H. tridens. The inbreeding coefficient of O. dehaani was significantly higher on the Pacific coast of the Tohoku region compared to other Japanese coasts. C. haematocheir and H. tridens had homogeneous genetic structures along the Japanese coast, but showed genetic differentiation of a local population at their range limits. Thus, O. dehaani showed little gene flow and clear genetic differentiation between populations in the Tohoku Pacific region and those on other Japanese coasts due to ocean currents. Although such a regional differentiation was not found in C. haematocheir and H. tridens, one population of C. haematocheir was genetically isolated at the edge of its distribution range and likely vulnerable to environmental changes.

    Abstract Plant species with overlapping distributions are expected to experience the same historical events. In contrast, species with different preferred habitat types may exhibit incongruent phylogeographic patterns because of their habitat‐dependent demographic changes in spite of their overlapping distributions. On the western side of the Japanese Archipelago, boreal forest and non‐forest vegetation were dominant during the last glacial period; subsequently, temperate forests expanded, and open vegetation (e.g., grasslands) decreased. Such vegetation shifts can result in incongruent phylogeographic patterns among temperate forest and grassland species; however, few phylogeographic studies have investigated this hypothesis. Here, we evaluated the phylogeographic structure of two related Geranium species that occur in grassland (Geranium krameri) and temperate forest (Geranium shikokianum) habitats using chloroplast genome sequencing and nuclear genome‐wide single‐nucleotide polymorphisms genotyping. The phylogeographic structure was stronger for the temperate forest species than the grassland species, despite its currently scattered distribution for grassland species. The observed patterns indicate that the phylogeographic histories of these species were influenced by their habitat configurations since the last glacial period. During the ice age, grasslands in Japan were much more widespread than today; this would have enabled the grassland species to form a continuous distribution, leading to low divergence among regional populations. In contrast, the significant genetic divergence within the forest species can be attributed to the glacial isolation of regional populations. Our genetic results suggest that vegetation transitions have variously controlled the population dynamics of two species with overlapping distributions.

    Abstract Premise Snow is an important environmental factor affecting plant distribution. Past changes in snowfall regimes may have controlled the demographies of snow‐dependent plants. However, our knowledge of changes in the distribution and demographies of such plants is limited because of the lack of fossil records. Methods Population genetic and landscape genetic analyses were used to investigate the response of population dynamics of Arnica mallotopus (Asteraceae)—a plant confined to heavy‐snow areas of Japan—to changes in snowfall regimes from the Last Glacial Period to the Holocene. Results The population genetic analysis suggested that the four geographic lineages diverged during the Last Glacial Period. The interaction between reduced snowfall and lower temperatures during this period likely triggered population isolation in separate refugia. Subpopulation differentiation in the northern group was lower than in the southern group. Our ecological niche model predicted that the current distribution was patchy in the southern region; that is, the populations were isolated by topologically flat and climatically unsuitable lowlands. The landscape genetic analysis suggested that areas with little snowfall acted as barriers to the Holocene expansion of species distribution and continued limiting gene flow between local populations. Conclusions These findings indicate that postglacial population responses vary among regions and are controlled by environmental and geographic factors. Thus, changes in snowfall regime played a major role in shaping the distribution and genetic structure of the snow‐dependent plant.

    Abstract Cycads represent an example of the success of evolutionary stasis. Despite their early origin, they survived multiple events of mass extinction and diversified in modern tropical ecosystems during the Cenozoic without major changes in their morphology. What factors have allowed their persistence and diversification despite their conservative nature? We reviewed documentation on the micro‐ and macro‐evolutionary processes involved in the diversification of the Neotropical genus Dioon. Dioon comprises 18 species from varied habitats in Mexico and Honduras, and serves as a model to understand the patterns of cycad diversification. Here, we synthesize evidence reached from different fields, especially biogeography, phylogenetics, population ecology, and speciation, to propose a mechanism that can explain the current patterns of biodiversity in Dioon. At the macroevolutionary scale, a Paleogene origin for Dioon is more likely than an alternative hypothesis of a Neogene origin. Dioon lineages have dispersed along with the expansion of tropical forests throughout main mountain chains. Subsequently, climate change, and particularly aridification, promoted the fragmentation of the tropical forests, allowing the main Dioon clades to evolve in isolation at distinct biogeographic regimes. At the microevolutionary scale, low seed dispersal capability, stochastic demographic processes, and niche conservatism restrict the lineages to isolate themselves at narrow habitats, promoting local adaptation in populations. Local adaptation seems to be a process achieved through many generations under stabilizing selection. Altogether, these processes shaped the diversification in Dioon. This review attempts to stimulate further research on cycads and other biological groups that have diversified despite their apparent evolutionary stasis.

    Abstract Aim The continental island system comprising Sakhalin, Hokkaido and the southern Kuril Islands (SHSK) in northeastern Asia serves as one of the southernmost habitats for many boreal and arctic organisms, with colonization via land bridges formed during glacial periods. To understand the impacts of past land‐bridge formation under Quaternary climate changes across SHSK, we investigated the demographic history of forest‐dwelling marten species. Location Sakhalin, Hokkaido and the southern Kuril Islands in northeastern Asia. Taxon Sable, Martes zibellina (Carnivora, Mustelidae). Methods We employed multiplexed inter‐simple sequence repeat genotyping by sequencing (MIG‐seq) to obtain genome‐wide single nucleotide polymorphisms (SNPs). We tested possible scenarios of colonization and diversification for SHSK sables using several population genetics approaches including clustering analysis, population tree estimation and approximate Bayesian computation modelling. We also examined haplotype diversity for the mitochondrial ND2 gene. Results The genetic diversity of the island populations and their affinity for continental populations were found to be higher in the order Sakhalin &gt; Hokkaido &gt; Iturup in both nuclear SNP and mitochondrial DNA analyses. Demographic analyses indicated that the sable migrated repeatedly from the continent, particularly to the neighbouring Sakhalin Island. However, only an earlier colonized lineage has persisted on marginal Iturup Island since the Middle Pleistocene. The stronger effects of repeated migrations and/or isolation influenced by the distance to the continent have shaped the contemporary genetic diversity and differentiation of sable populations in SHSK. Main Conclusions Genome‐wide and comprehensive sampling approaches demonstrated that the forest‐dwelling sable had long‐term persistence with partial admixture of multiple lineages in SHSK, suggesting the existence of forest corridors and refugia on the islands during the last several glacial periods. The SHSK system of continental islands is valuable for understanding the impacts of Quaternary climate changes on the genetic diversity and evolutionary histories of boreal organisms.

    The Ryukyu Islands of Japan are a biodiversity hotspot due to geographical and historical factors. Tricyrtis formosana is a perennial herbaceous plant that commonly found in Taiwan. But only a few populations have been identified in a limited habitat on Iriomote Island, while populations of unknown origin occur near human settlements in an area on the main island of Okinawa. To better understand these populations of the phylogenetic uniqueness and intrinsic vulnerability, we conducted comparative analyses including (1) phylogeny and population structure with MIG-seq data, (2) photosynthesis-related traits of plants grown under common conditions and (3) transcriptome analysis to detect deleterious variations. Results revealed that T. formosana was split into two clades by the congeners and that Iriomote and Okinawa populations independently derived from ancestral Taiwanese populations in each clade. Photosynthetic efficiency was lowest in the Iriomote population, followed by Okinawa and Taiwan. Transcriptome analysis showed that the Iriomote population accumulated more deleterious variations, suggesting intrinsic vulnerability. These results indicate that each T. formosana population in Japan is phylogenetically unique and has been independently dispersed from Taiwan, and that the Iriomote population presents a high conservation difficulty with a unique photosynthesis-related characteristic and a larger amount of deleterious variations.

    Abstract Population outbreaks of insects provide an excellent opportunity to elucidate their evolutionary history. In this study, we uncovered the phylogenetic relationships of Dicraeus spp. in Japan and compared the population genetic structure of two bamboo-feeding Dicraeus spp., Dicraeus phyllostachyus and Dicraeus nartshukae, by leveraging a recent nationwide mass flowering event of several bamboo species in Japan. We performed analysis using mitochondrial COI gene sequencing and genome-wide single-nucleotide polymorphisms detected by multiplexed inter-simple sequence repeat genotyping by sequencing (MIG-seq). We found genetic similarity in COI haplotypes over a large geographical range in the two Dicraeus spp., but, for both species, no concordance was detected between the collected host plants and genetic structures. In the genome-wide single-nucleotide polymorphism data, no clear genetic clusters were detected for D. phyllostachyus populations, whereas D. nartshukae populations were divided into two groups, in the north and south of Japan. Demographic analysis indicated that D. phyllostachyus had greatly expanded its population recently compared with D. nartshukae. These contrasting patterns between the two species might reflect the differences in the demographic history between the species. Our study suggested that the mass flowering event might cascade to the genetic structure of the florivorous insects through trophic interactions.

    Abstract Recent phylogeographical studies have revealed that refugia sometimes retain high levels of genetic heterogeneity due to multiple colonization events, a phenomenon defined as ‘refugia within refugium’. In previous research, we reported a complex genetic structure within the Geranium yesoense complex, an alpine plant found in an interglacial refugium at high elevation in Central Japan, probably resulting from multiple colonization and hybridization events. However, we were unable to evaluate instances of introgression due to limited sample size. In the present study, we performed additional chloroplast genome sequencing, along with Sanger sequencing of selected chloroplast DNA regions, to elucidate the phylogenetic relationships among the refugial populations. The chloroplast genome sequence of a sample from Mt. Asama (an important refugium) was nested within the northern lineage (i.e. var. yesoense and var. pseudopratense), and haplotypes from Mt. Asama and Mt. Ibuki were also grouped with those of the northern lineage. Although our previous study suggested hybridization events between northern and southern lineages (i.e. var. nipponicum) at Mt. Asama, haplotypes from the southern lineage were not detected at range margins. This suggests that directional introgression occurred in these regions. Overall, our results further support that genetic heterogeneity within these refugia was amplified by recolonization and hybridization during past climate oscillations.

    Abstract Vicia sepium (bush vetch) is a perennial legume widely distributed throughout the Eurasian continent. However, its distribution in Japan is limited to Mt. Ibuki and small parts of central and southern Hokkaido. Therefore, each Japanese V. sepium lineage has been considered to have been introduced separately from Europe. Here, we examined whether the species was introduced or not on the basis of cpDNA sequences and genome-wide SNPs from Japanese and overseas samples. Both the cpDNA haplotype network and the nuclear DNA phylogenetic tree showed that Japanese V. sepium is monophyletic. Furthermore, although the nuclear DNA phylogenetic tree also showed that each lineage is clearly monophyletic, genetic admixture of the genetic cluster dominated in the Hokkaido lineage was also detected in the Mt. Ibuki lineage. Population divergence analysis showed that the two lineages diverged during the last glacial period. The Mt. Ibuki lineage showed a sudden population decline 300–400 years ago, indicating that some anthropogenic activity might be involved, while the Hokkaido lineage showed a gradual population decline from 5000 years ago. Consequently, these two lineages show low current genetic diversity compared with overseas lineages. These results show that the Japanese V. sepium is not introduced but is native.

    Oceanic islands offer valuable natural laboratories for studying evolution. The Izu Islands, with their recent geological origin, provide an exceptional opportunity to explore the initial evolution on oceanic islands. Another noteworthy aspect is the absence of bumblebee species on most Izu Islands. We used ecological, morphological, and molecular data to investigate the impact of bumblebee absence on the evolution of two closely related orchid species, Goodyera henryi and Goodyera similis, focusing on Kozu Island, the Izu Islands. Our investigation revealed that while G. henryi exclusively relies on a bumblebee species for pollination on the mainland, G. similis is pollinated by scoliid wasps on both the mainland and the island. Intriguingly, all specimens initially categorized as G. henryi on Kozu Island are hybrids of G. henryi and G. similis, leading to the absence of pure G. henryi distribution on the island. These hybrids are pollinated by the scoliid wasp species that also pollinates G. similis on the island. The absence of bumblebees might result in sporadic and inefficient pollination of G. henryi by scoliid wasps, consequently promoting hybrid proliferation on the island. Our findings suggest that the absence of bumblebees can blur plant species boundaries.

    Exploring how organisms overcome geographical barriers to dispersal is a fundamental question in biology. Passive long-distance dispersal events, although infrequent and unpredictable, have a considerable impact on species range expansions. Despite limited active dispersal capabilities, many stick insect species have vast geographical ranges, indicating that passive long-distance dispersal is vital for their distribution. A potential mode of passive dispersal in stick insects is via the egg stage within avian digestive tracts, as suggested by experimental evidence. However, detecting such events under natural conditions is challenging due to their rarity. Therefore, to indirectly assess the potential of historical avian-mediated dispersal, we examined the population genetic structure of the flightless stick insect Ramulus mikado across Japan, based on a multifaceted molecular approach [cytochrome oxidase subunit I (COI) haplotypes, nuclear simple sequence repeat markers and genome-wide single nucleotide polymorphisms]. Subsequently, we identified unique phylogeographic patterns, including the discovery of identical COI genotypes spanning considerable distances, which substantiates the notion of passive long-distance genotypic dispersal. Overall, all the molecular data revealed the low and mostly non-significant genetic differentiation among populations, with identical or very similar genotypes across distant populations. We propose that long-distance dispersal facilitated by birds is the plausible explanation for the unique phylogeographic pattern observed in this flightless stick insect.

    <jats:p>The rates of appearance of new mutations play a central role in evolution. However, mutational processes in natural environments and their relationship with growth rates are largely unknown, particular in tropical ecosystems with high biodiversity. Here, we examined the somatic mutation landscapes of two tropical trees, Shorea laevis (slow-growing) and S. leprosula (fast-growing), in central Borneo, Indonesia. Using newly-constructed genomes, we identified a greater number of somatic mutations in tropical trees than in temperate trees. In both species, we observed a linear increase in the number of somatic mutations with physical distance between branches. However, we found that the rate of somatic mutation accumulation per meter of growth was 3.7-fold higher in S. laevis than in S. leprosula. This difference in the somatic mutation rate was scaled with the slower growth rate of S. laevis compared to S. leprosula, resulting in a constant somatic mutation rate per year between the two species. We also found that somatic mutations are neutral within an individual, but those mutations transmitted to the next generation are subject to purifying selection. These findings suggest that somatic mutations accumulate with absolute time and older trees have a greater contribution towards generating genetic variation.</jats:p> <jats:p>The significance of our study lies in the discovery of an absolute time-dependent accumulation of somatic mutations in long-lived tropical trees, independent of growth rate. Through a comparative analysis of somatic mutation landscapes in slow- and fast-growing species, we observed a clock-like accumulation of somatic mutations in both species, regardless of their growth rates. Although the majority of somatic mutations were restricted to a single branch, we also identified mutations present in multiple branches, likely transmitted during growth. Our findings suggest that older trees make a greater contribution towards generating genetic variation.</jats:p>

    Abstract Estimating the role of specific processes in the spread of alien species necessitates the determination of introduction pathways and source populations of invaded areas. Alien grasses in the genus Lolium that have extensively invaded Japan provide a unique opportunity to estimate the expansion process through direct comparison between source and naturalised populations because the introduction pathways, contaminants in grain commodities and commercial cultivars for fodder crops or revegetation materials are well‐known. Therefore, by directly comparing source and naturalised populations, we estimated the introduction pathways and whether adaptative evolution occurred in Lolium species on sandy coasts in Japan. Lolium individuals sampled from naturalised populations in croplands, seaports, and sandy coasts were compared with those from two introduction sources for morphological and genetic variations based on a genome‐wide single nucleotide polymorphism analysis and a common garden experiment. Furthermore, we conducted a reciprocal transplant experiment between cropland and sandy coast. Populations naturalised in croplands were closely related to the cultivars, whereas those naturalised in seaports and sandy coasts were associated with contaminants. These results indicate that the cropland and sandy coast populations are derived from cultivars and contaminants, respectively. In addition, asymmetric gene flow from cropland populations to sandy coast populations was observed. The reciprocal transplant experiment clearly demonstrated the home site advantage; populations derived from croplands yielded higher floret numbers than those derived from other habitats at the cropland site; sandy coast populations had higher survival rates than those from croplands at the coastal site. Port populations exhibited a similar tendency as sandy coast populations, indicating that contaminants may be originally adapted to salty and dry environments, such as that in sandy coasts. The flowering phenology in the sandy coast populations evolved in the late flowering; therefore, late flowering alleles may have been transferred from cropland populations to sandy coast populations. Synthesis. We demonstrated that two congeneric species with different ecological characteristics were introduced through multiple introduction pathways and spread across different habitats. A direct comparison between source and naturalised populations can considerably elucidate the patterns and processes of biological invasions.

    The rates and patterns of somatic mutations in wild plants, as well as how they relate to longevity, are largely unknown1–3. Here, we examined the somatic mutation landscapes of slow- and fast-growing tropical species in central Borneo, Indonesia. Using newly-constructed genomes, we identified an average of 480 mutations in the slow-growing species (265-year-old, 44.1 m in height), which was five times greater than that observed in the fast-growing species (66-year-old, 43.9 m). The number of somatic mutations increased linearly with branch length. The somatic mutation rate per meter was higher in the slow-growing species, yet the rate per year remained constant across both species. The mutational spectra exhibited a dominance of spontaneous mutations, specifically cytosine-to-thymine substitutions at CpG sites. An analysis of nucleotide substitutions at both the intra- and inter-individual level revealed that somatic mutations are neutral within an individual, but those mutations transmitted to the next generation are subject to purifying selection. We developed a model to evaluate the relative contribution of cell division on mutational processes, and postulate that cell-division independent mutagenesis predominates. These findings deepen our understanding of mutational processes underlying the generation of genetic diversity in a tropical ecosystem.

    Abstract Recently, many new cultivars are taken abroad illegally, which is now considered an international issue. Botanical evidence found at a crime scene provides valuable information about the origin of the sample. However, botanical resources for forensic evidence remain underutilized because molecular markers, such as microsatellites, are not available without a limited set of species. Multiplexed ISSR genotyping by sequencing (MIG-seq) has been used to determine a number of genome-wide genetic markers and can be applied for every plant, including species that lack genetic information. Camellia cultivars are popular worldwide and are often planted in many gardens and bred to make new cultivars. In this study, we aimed to analyze Camellia cultivars/species through MIG-seq. Through this, MIG-seq could discriminate similar samples, such as bud mutations and closely related samples which could not be distinguished based on morphological features. This discrimination was consistent with that of a previous study which classified cultivars by short tandem repeat (STR) markers, indicating that MIG-seq has the same or higher discrimination ability as STR markers. Furthermore, based on our results, unknown phylogenetic relationships were observed. Since MIG-seq can be applied to unlimited species and low-quality DNA, it may be useful for various scientific fields.

    The systematics of the Old World Spiranthes sinensis (Pers.) Ames species complex (Orchidaceae) has been complicated by its wide distribution and morphological variations. Within the species complex, S. australis Lindl. has been generally accepted as the only Spiranthes Rich. species distributed on the Japanese mainland. The present study provides morphological, phylogenetic, and ecological evidence for the recognition of S. hachijoensis Suetsugu as a new species of the S. sinensis species complex on the Japanese mainland. Spiranthes hachijoensis is morphologically similar to S. hongkongensis S.Y. Hu & Barretto and S. nivea T.P. Lin & W.M. Lin, sharing a degenerated rostellum, pollinia without a viscidium, and distinctly trilobed stigma. However, the taxon can be morphologically distinguished from S. hongkongensis by its glabrous rachis, ovaries, and sepals, and from S. nivea by its papillate labellum disc, larger papillate basal labellum callosities, and glabrous rachis, ovaries, and sepals. The autogamy and flowering phenology (i.e., earlier flowering) of S. hachijoensis are most likely responsible for premating isolation from the sympatric S. australis. A MIG-seq-based high-throughput molecular analysis indicated that the genetic difference between S. hachijoensis and its putative sister species S. sinensis is comparable to, or even greater than, the genetic difference between pairs of other species within the S. sinensis species complex. Our multifaceted approach strongly supports the recognition of S. hachijoensis as a morphologically, phenologically, phylogenetically, and ecologically distinct species.

    As biodiversity loss continues, there is an urgent need to develop efficient conservation measures to protect diversity with limited conservation resources. Conservation targets have generally been selected based on their population size, but more detailed assessments clarifying the phylogenetic genetic status, history, and phylogenetic uniqueness of rare species is crucial to set more appropriate and effective conservation measures. In Japan, the Act on Conservation of Endangered Species of Wild Fauna and Flora designated endangered plants with high conservation priority, but &amp;gt;40% of these species also grow overseas. We conducted comparative analyses based on ddRADseq and MIG-seq to evaluate the population conservation status and value of Vaccinium emarginatum and Elatostema platyphyllum which are growing across national borders at the eastern edge of their species distribution range. The analyses revealed contrasting conservation status between the two species; the Japanese population of V. emarginatum had lower genetic diversity at the individual level and phylogenetically differentiated from Taiwanese populations, while that of E. platyphyllum had higher diversity at the individual level and is a relatively recent migrant with little phylogenetical differentiation from Taiwanese populations. The two species, which share the common feature of being critically rare in Japan, showed contrasting genetic/phylogenetic characteristics. This study provided useful information for appropriate conservation measures based on species’ phylogenetic traits and genetic diversity.

    Due to their reduced morphology, non-photosynthetic plants have been one of the most challenging groups to delimit to species level. The mycoheterotrophic genus Monotropastrum, with the monotypic species M. humile, has been a particularly taxonomically challenging group, owing to its highly reduced vegetative and root morphology. Using integrative species delimitation, we have focused on Japanese Monotropastrum, with a special focus on an unknown taxon with rosy pink petals and sepals. We investigated its flowering phenology, morphology, molecular identity, and associated fungi. Detailed morphological investigation has indicated that it can be distinguished from M. humile by its rosy pink tepals and sepals that are generally more numerous, elliptic, and constantly appressed to the petals throughout its flowering period, and by its obscure root balls that are unified with the surrounding soil, with root tips that hardly protrude. Based on genome-wide single-nucleotide polymorphisms, molecular data has provided clear genetic differentiation between this unknown taxon and M. humile. Monotropastrum humile and this taxon are associated with different Russula lineages, even when they are sympatric. Based on this multifaceted evidence, we describe this unknown taxon as the new species M. kirishimense. Assortative mating resulting from phenological differences has likely contributed to the persistent sympatry between these two species, with distinct mycorrhizal specificity.

    Anthropogenic activities, such as the movement of plants through greening, can result in genetic disturbance that can interfere with local adaptation in wild populations. Although research is underway to prevent genetic disturbance associated with greening, genetic disturbance of intraspecific polyploidy, which is estimated to be present in 24% of vascular plants, has not been well studied. Liriope muscari is a polyploid complex with known diploid (2n = 36), tetraploid (2n = 72), and hexaploid (2n = 108) forms. The plants of this species tolerate dry and hot conditions and are therefore frequently used for greening and gardening. However, the distribution of this polyploid in Japan, its genetic structure, and genetic disturbance are not known. In this study, we investigated the polyploidy distribution and genetic structure in naturally distributed L. muscari in Japan using chloroplast DNA (cpDNA) haplotypes and nuclear DNA (nDNA). Commercially produced individuals were also studied and compared with natural populations to assess any genetic disturbance of the ploidy complex in this species. Chromosome counts, cpDNA, and nDNA results showed three genetically and cytologically distinct groups in Japan: first, a tetraploid group in mainland Japan; second, a hexaploid group in the Ryukyu Islands; and third, a diploid and tetraploid group in the Ryukyu Islands. Significant isolation by distance was also detected within the three groups (p = 0.001). Genetic disturbance due to greening and gardening should be avoided among the three groups. Genetic disturbance can be reduced by using individuals derived from natural populations that are close to the sites used for greening and gardening. For commercially produced individuals, genetic disturbance is unlikely in the Kanto region, an area of high usage, while genetic disturbance is thought possible in the Ryukyu Islands.

    Abstract—Lithocarpus cadamensis Ngoc &amp; Son, a new species of Fagaceae, is described and illustrated from Mt. Ca Dam, Tra Bong District, Quang Ngai Province, central Vietnam. The new species is characterized by its large leaf blades with long petioles, solitary and subsessile cupules which almost completely cover the nut, and spiny cupule scales, in a combination that clearly differs from the previously known species of Lithocarpus including the most similar species in the region, L. campylolepis, L. eucalyptifolius, and L. gougerotae. A MIG-seq phylogeny based on genome-wide SNPs reveals a phylogenetic position close to L. eucalyptifolius, from which the new species is differentiated by multiple morphological characters. A morphological description and comparison with related species, photographs, line drawing, preliminary conservation status, and DNA barcode sequences are provided for the new species.

    Global climate change poses a significant threat to the habitat connectivity of cold-water-adapted organisms, leading to species extinctions. Because gene flow is itself a functional connectivity among wild populations, if gene flow is modeled by landscape variables, changes in population connectivity could be predicted. In this study, using a model-based riverscape genetics technique and a hydrological model to estimate water temperature, we inferred the determinants of and future changes in gene flow of the fluvial sculpin Cottus nozawae in the upstream section of the Sorachi River, Hokkaido, Japan. As a result of model selection, stream order, water temperature, slope, and distance were detected as landscape variables affecting the strength of gene flow in each stream section. In particular, the trend of greater gene flow in sections with higher stream order and lower temperature fluctuations or summer water temperatures was pronounced. The map from the model showed that gene flow is overall prevented in small tributaries in the southern area, where spring-fed environments are less prevalent. Estimating future changes in gene flow using future water temperature predictions, genetic connectivity was predicted to decrease dramatically until the end of the 21st century under IPCC representative concentration pathway scenario 8.5 (RCP8.5).

    Contrasting theories exist regarding how Norway spruce (Picea abies) recolonized Fennoscandia after the last glaciation and both early Holocene establishments from western microrefugia and late Holocene colonization from the east have been postulated. Here, we show that Norway spruce was present in southern Fennoscandia as early as 14.7 ± 0.1 cal. kyr BP and that the millennia-old clonal spruce trees present today in central Sweden likely arrived with an early Holocene migration from the east. Our findings are based on ancient sedimentary DNA from multiple European sites (N = 15) combined with nuclear and mitochondrial DNA analysis of ancient clonal (N = 135) and contemporary spruce forest trees (N = 129) from central Sweden. Our other findings imply that Norway spruce was present shortly after deglaciation at the margins of the Scandinavian Ice Sheet, and support previously disputed finds of pollen in southern Sweden claiming spruce establishment during the Lateglacial.

    BACKGROUND: Establishing fecal microbiota transplantation (FMT) to prevent multifactorial diarrhea in calves is challenging because of the differences in farm management practices, the lack of optimal donors, and recipient selection. In this study, the underlying factors of successful and unsuccessful FMT treatment cases are elucidated, and the potential markers for predicting successful FMT are identified using fecal metagenomics via 16S rRNA gene sequencing, fecal metabolomics via capillary electrophoresis time-of-flight mass spectrometry, and machine learning approaches. RESULTS: Specifically, 20 FMT treatment cases, in which feces from healthy donors were intrarectally transferred into recipient diarrheal calves, were conducted with a success rate of 70%. Selenomonas was identified as a microorganism genus that showed significant donor-recipient compatibility in successful FMT treatments. A strong positive correlation between the microbiome and metabolome data, which is a prerequisite factor for FMT success, was confirmed by Procrustes analysis in successful FMT (r = 0.7439, P = 0.0001). Additionally, weighted gene correlation network analysis confirmed the positively or negatively correlated pairs of bacterial taxa (family Veillonellaceae) and metabolomic features (i.e., amino acids and short-chain fatty acids) responsible for FMT success. Further analysis aimed at establishing criteria for donor selection identified the genus Sporobacter as a potential biomarker in successful donor selection. Low levels of metabolites, such as glycerol 3-phosphate, dihydroxyacetone phosphate, and isoamylamine, in the donor or recipients prior to FMT, are predicted to facilitate FMT. CONCLUSIONS: Overall, we provide the first substantial evidence of the factors related to FMT success or failure; these findings could improve the design of future microbial therapeutics for treating diarrhea in calves.

    Standard models of plant speciation assume strictly dichotomous genealogies in which a species, the ancestor, is replaced by two offspring species. The reality in wind-pollinated trees with long evolutionary histories is more complex: species evolve from other species through isolation when genetic drift exceeds gene flow; lineage mixing can give rise to new species (hybrid taxa such as nothospecies and allopolyploids). The multi-copy, potentially multi-locus 5S rDNA is one of few gene regions conserving signal from dichotomous and reticulate evolutionary processes down to the level of intra-genomic recombination. Therefore, it can provide unique insights into the dynamic speciation processes of lineages that diversified tens of millions of years ago. Here, we provide the first high-throughput sequencing (HTS) of the 5S intergenic spacers (5S-IGS) for a lineage of wind-pollinated subtropical to temperate trees, the Fagus crenata - F. sylvatica s.l. lineage, and its distant relative F. japonica. The observed 4963 unique 5S-IGS variants reflect a complex history of hybrid origins, lineage sorting, mixing via secondary gene flow, and intra-genomic competition between two or more paralogous-homoeologous 5S rDNA lineages. We show that modern species are genetic mosaics and represent a striking case of ongoing reticulate evolution during the past 55 million years.

    Geographic differences in floral traits may reflect geographic differences in effective pollinator assemblages. Independent local adaptation to pollinator assemblages in multiple regions would be expected to cause parallel floral trait evolution, although sufficient evidence for this is still lacking. Knowing the intraspecific evolutionary history of floral traits will reveal events that occur in the early stages of trait diversification. In this study, we investigated the relationship between flower spur length and pollinator size in 16 populations of Aquilegia buergeriana var. buergeriana distributed in four mountain regions in the Japanese Alps. We also examined the genetic relationship between yellow- and red-flowered individuals, to see if color differences caused genetic differentiation by pollinator isolation. Genetic relationships among 16 populations were analyzed based on genome-wide single-nucleotide polymorphisms. Even among populations within the same mountain region, pollinator size varied widely, and the average spur length of A. buergeriana var. buergeriana in each population was strongly related to the average visitor size of that population. Genetic relatedness between populations was not related to the similarity of spur length between populations; rather, it was related to the geographic proximity of populations in each mountain region. Our results indicate that spur length in each population evolved independently of the population genetic structure but in parallel in response to local flower visitor size in different mountain regions. Further, yellow- and red-flowered individuals of A. buergeriana var. buergeriana were not genetically differentiated. Unlike other Aquilegia species in Europe and America visited by hummingbirds and hawkmoths, the Japanese Aquilegia species is consistently visited by bumblebees. As a result, genetic isolation by flower color may not have occurred.

    Species delimitation within the genus Goodyera is challenging among closely related species, because of phenotypic plasticity, ecological variation, and hybridization that confound identification methods based solely on morphology. In this study, we investigated the identity of Goodyeracrassifolia H.-J.Suh, S.-W.Seo, S.-H.Oh & T.Yukawa, morphologically similar to Goodyeraschlechtendaliana Rchb.f. This recently described taxon has long been known in Japan as "Oh-miyama-uzura" or "Gakunan" and considered a natural hybrid of G.schlechtendaliana and G.similis Blume (= G.velutina Maxim. ex Regel). Because the natural hybrid between G.schlechtendaliana and G.similis was described as G.×tamnaensis N.S.Lee, K.S.Lee, S.H.Yeau & C.S.Lee before the description of G.crassifolia, the latter might be a synonym of G.×tamnaensis. Consequently, we investigated species boundaries and evolutionary history of G.crassifolia and its closely related taxa based on multifaceted evidence. Consequently, morphological examination enabled us to distinguish G.crassifolia from other closely related species owing to the following characteristics: coriaceous leaf texture, laxly flowered inflorescence, long pedicellate ovary, large and weakly opened flowers, and column with lateral appendages. Ecological investigation indicates that G.crassifolia (2n = 60) is agamospermous, requiring neither pollinators nor autonomous self-pollination for fruit set, whereas G.schlechtendaliana (2n = 30) is neither autogamous nor agamospermous but is obligately pollinator-dependent. MIG-seq-based phylogenetic analysis provided no evidence of recent hybridization between G.crassifolia and its close congeners. Thus, molecular phylogeny reconstructed from MIG-seq data together with morphological, cytological, and ecological analyses support the separation of G.crassifolia as an independent species.

    According to the contemporary classification of Hydrangea native to Japan, H.serrata is a polymorphic species including six varieties. We discovered a plant identified as H.serrata, but morphologically distinct from previously known varieties, in Yakushima island where approximately 50 endemic species are known. To determine the relationship of this plant with previously known varieties, we examined morphology and constructed a highly resolved phylogeny of H.serrata and its relatives using three chloroplast genomic regions, rbcL, trnL intron, psbA-trnH, and two nuclear genomic regions, ITS1 and ITS2, and Multiplex ISSR genotyping by sequencing (MIG-seq). Based on these morphological and phylogenetic observations, we describe Hydrangeaacuminatasubsp.yakushimensissubsp. nov. as a newly discovered lineage in Yakushima, Japan and propose Hydrangeaminamitanii stat. nov. and Hydrangeaacuminatasubsp.australisstat. nov. which were previously treated as varieties of H.serrata.

    Biogenic volatile organic compounds emitted from plants are important constituents of atmospheric chemistry and play a major role in the resistance of plants against various environmental stresses. However, little is known about how abiotic and biotic environments on a geographic scale relate to diversifications of the emission. Here, we present variations of terpenes stored in and emitted from leaves of a single species in a common garden, using genetically differentiated local populations of Japanese cedar, the most dominant and widely distributed tree species in Japan. Furthermore, we determined the composition of fungal communities in 50 locations, based on the presence or absence of 158 fungal species inhabiting the cedar. The results showed that terpenoids, especially those that are emitted, were highly diversified and geographically structured among the 12 populations. The total amount of stored terpenes was negatively affected by warm and less-snow climates. On the other hand, variations in some emitted terpenoid species among the populations were correlated to antagonistic fungal species inhabiting the Japanese cedar. We propose that the diversification of composition and amount of stored and emitted terpenoids in the tree species is not only structured by climate, but also antagonistic fungal communities through biological interactions.

    It is vital to measure the levels of genetic diversity and differentiation between populations in a species to understand the current genetic structure and evolution of the species. Here, MIG-seq (multiplexed inter-simple sequence repeat genotyping by sequencing) was employed to assess the genetic variation in two tropical leguminous tree species, Dalbergia cochinchinensis and D. nigrescens, in Cambodia and Thailand. Sequence data for 255-618 loci, each with an approximate length of 100 bp, were obtained, and the nucleotide diversity, Tajima's D and FST were computed. The estimates calculated from the data obtained by MIG-seq were compared to those obtained by Sanger sequencing of nine nuclear coding genes in D. cochinchinensis in our previous study. The nucleotide diversity at the MIG-seq loci was slightly higher than that at silent sites in the coding loci, whereas the FST values at the MIG-seq loci were generally lower than those at the coding loci, although the differences were not significant. Moreover, nucleotide diversities within populations of the two species were similar to each other, at approximately 0.005. Three and four population clusters were genetically recognized in D. cochinchinensis and D. nigrescens, respectively. Although the populations were differentiated from each other, the levels of differentiation among them, as measured by FST, were higher in D. cochinchinensis than in D. nigrescens. This indicates higher levels of gene flow between the populations in the latter species. We recommend using MIG-seq for quick surveys of genetic variation because it is cost-effective and results in smaller variance in the estimates of population genetic parameters.

    A new species, Actinodaphne lambirensis Tagane, Yahara & N. Okabe (Lauraceae) from Lambir Hills National Park, Miri District, Sarawak, Malaysia, is described and illustrated. It is characterized by glabrous twigs and leaves, small lamina (4.3–9.2 × 1.7–2.8 cm), and long fruiting peduncles. Because only fruiting specimens were available, the position of A. lambirensis was determined by the phylogenetic trees based on 22 species of Actinodaphne, including the type species of the genus, A. pruinosa Nees, and 11 species of Neolitsea from Southeast Asia using multiplexed inter-simple sequence repeats genotyping by sequencing (MIG-seq). Additionally, a phylogenetic tree was constructed using internal transcribed spacer (ITS) sequences for 36 species of Actinodaphne and 40 species of Neolitsea that include our MIGseq samples and additional species for which ITS sequences were determined in previous studies. Both the MIG-seq tree and ITS tree supported A. lambirensis as belonging with Actinodaphne.

    <title>Abstract</title> Recent studies have found that geographical fragmentation and recurrent colonization result in complex genetic structures in refugial areas. This phenomenon, known as ‘refugia within refugium’, has been identified from many geographical locations. In Japan, the high-elevation mountains of central Honshu provided an interglacial refugium for alpine plants. Here we focused on the Geranium yesoense complex, which exhibits increased morphological variation in the refugial area, to determine whether this variation was shaped by recurrent colonization, range fragmentation or phenotypic changes independent of population history. We analysed single nucleotide polymorphism data and chloroplast genome sequences. Diversification in the G. yesoense species complex occurred in the mid-Pleistocene. The varieties are distinct entities and suggest the presence of a genetic cluster with highly disjunct distributions, occurring both in northern Japan and in southern refugial areas in central Honshu. Demographic analysis suggests that a single ancestral variety (var. nipponicum) evolved in the alpine region of central Honshu, and that subsequent migration from one of the two diverged northern varieties (var. pseudopratense) led to secondary contact with var. nipponicum during the last glacial period. Recolonization into refugial populations in central Honshu and hybridization between diverged populations have resulted in complex genetic structures among refugial populations.

    An unknown taxon of Stellaria was discovered in Yakushima, a Japanese island known to harbor several endemic species. To determine the identity of this taxon, this study employed MIG-seq for the reconstruction of a finely resolved phylogenetic tree of the newly discovered taxon, along with some related species of Stellaria. The results showed that the newly discovered taxon is a relative of S.alsine. Based on this result, Stellariaalsinesubsp.nanasubsp. nov. was published.

    Meehania montis-koyae Ohwi (Lamiaceae), which has been considered a narrow endemic and endangered species in Japan, was found in eastern China in 2011. China and Japan belong to the same floristic region and share many plant species, but it is very rare that Japanese narrow endemic species are newly found outside of the country. We examined herbarium specimens of both countries, and conducted analyses of molecular phylogenetics, population genetics, and divergence time estimation using two nuclear (ITS and ETS) gene regions and MIG-seq data. Chinese plants tend to become larger than Japanese, and they are different in leaf shape and floral features. Molecular phylogenetic analysis shows Chinese and Japanese M. montis-koyae are the closest relatives to each other. Population genetic analysis indicates no current gene flow between the Chinese and Japanese populations, and divergence time analysis shows they were separated during the late Miocene. We reach the conclusion that Chinese and Japanese M. montis-koyae have already become distinct biological entities, and a new taxon name Meehania zheminensis A. Takano, Pan Li, G.-H.Xia is proposed for the Chinese plants. A key to Asian Meehania species is provided.

    Edaphic specialization is one of the main drivers of plant diversification and has multifaceted effects on population dynamics. Carex angustisquama is a sedge plant growing only on heavily acidified soil in solfatara fields, where only extremophytes can survive. Because of the lack of closely related species in similar habitats and its disjunct distribution, the species offers ideal settings to investigate the effects of adaptation to solfatara fields and of historical biogeography on the genetic consequences of plant edaphic specialization to solfatara fields. Here, genome-wide single nucleotide polymorphisms were used to reveal the phylogenetic origin of C. angustisquama, and 16 expressed sequence tag-simple sequence repeat markers were employed to infer population demography of C angustisquama. Molecular phylogenetic analysis strongly indicated that C. angustisquama formed a monophyletic clade with Carex doenitzii, a species growing on nonacidified soil in the sympatric subalpine zone. The result of population genetic analysis showed that C. angustisquama has much lower genetic diversity than the sister species, and notably, all 16 loci were completely homozygous in most individuals of C. angustisquama. Approximate Bayesian computation analysis supported the model that assumed hierarchical declines of population size through its evolutionary sequence. We propose that the edaphic specialist in solfatara fields has newly attained the adaptation to solfatara fields in the process of speciation. Furthermore, we found evidence of a drastic reduction in genetic diversity in C. angustisquama, suggesting that the repeated founder effects associated with edaphic specialization and subsequent population demography lead to the loss of genetic diversity of this extremophyte in solfatara fields.

    White-spotted charr (Salvelinus leucomaenis leucomaenis) is an anadromous fish that has been severely harmed by human land-use development, particularly through habitat fragmentation. However, the anthropogenic impacts on populations of this species have not been evaluated, except those on small dammed-off populations. Using multiplexed ISSR genotyping by sequencing, we investigated the genetic structure of white-spotted charr in four tributaries in the upper section of the Kanayama Dam in the Sorachi River, Hokkaido Island, Japan. There were no distinct genetic structures (FST = 0.014), probably because some active individuals migrate frequently among tributaries. By model-flexible demographic simulation, historical changes in the effective population size were inferred. The result indicates that the population size has decreased since the end of the last glacial period, with three major population decline events, including recent declines that were probably associated with recent human activities. Nevertheless, populations in the watershed upstream of the Kanayama Dam are still expected to be at low risk of immediate extinction, owing to the large watershed size and the limited number of small check dams. An effective conservation measure for sustaining the white-spotted charr population is to maintain high connectivity between tributaries, such as by providing fishways in check dams during construction.

    Natural history collections and tropical tree diversity are both treasure troves of biological and evolutionary information, but their accessibility for scientific study is impeded by a number of properties. DNA in historical specimens is generally highly fragmented, complicating the recovery of high-grade genetic material. Furthermore, our understanding of hyperdiverse, wide-spread tree assemblages is obstructed by extensive species ranges, fragmented knowledge of tropical tree diversity and phenology, and a widespread lack of species-level diagnostic characters, prohibiting the collecting of readily identifiable specimens which can be used to build, revise or strengthen taxonomic frameworks. This, in turn, delays the application of downstream conservation action. A sizable component of botanical collections are sterile-thus eluding identification and are slowing down progress in systematic treatments of tropical biodiversity. With rapid advances in genomics and bioinformatic approaches to biodiversity research, museomics is emerging as a new field breathing life into natural collections that have been built up over centuries. Using MIGseq (multiplexed ISSR genotyping by sequencing), we generated 10,000s of short loci, for both freshly collected materials and museum specimens (aged >100 years) of Lithocarpus-a widespread tropical tree genus endemic to the Asian tropics. Loci recovery from historical and recently collected samples was not affected by sample age and preservation history of the study material, underscoring the reliability and flexibility of the MIGseq approach. Phylogenomic inference and biogeographic reconstruction across insular Asia, highlights repeated migration and diversification patterns between continental regions and islands. Results indicate that co-occurring insular species at the extremity of the distribution range are not monophyletic, raising the possibility of multiple independent dispersals along the outer edge of Wallacea. This suggests that dispersal of large seeded tree genera throughout Malesia and across Wallacea may have been less affected by large geographic distances and the presence of marine barriers than generally assumed. We demonstrate the utility of MIGseq in museomic studies using non-model taxa, presenting the first range-wide genomic assessment of Lithocarpus and tropical Fagaceae as a proof-of-concept. Our study shows the potential for developing innovative genomic approaches to improve the capture of novel evolutionary signals using valuable natural history collections of hyperdiverse taxa.

    BACKGROUND & AIMS: Organ-level research using an animal model lacking Il2rg, the gene responsible for X-linked severe combined immunodeficiency (X-SCID), is clinically unavailable and would be a powerful tool to gain deeper insights into the symptoms of patients with X-SCID. METHODS: We used an X-SCID animal model, which was first established in our group by the deletion of Il2rg gene in pigs, to understand the clinical signs from multiple perspectives based on pathology, immunology, microbiology, and nutrition. We also treated the X-SCID pigs with bone marrow transplantation (BMT) for mimicking a current therapeutic treatment for patients with X-SCID and investigated the effect at the organ-level. Moreover, the results were confirmed using serum and fecal samples collected from patients with X-SCID. RESULTS: We demonstrated that X-SCID pigs completely lacked Peyer's patches (PPs) and IgA production in the small intestine, but possessed some dysfunctional intestinal T and B cells. Another novel discovery was that X-SCID pigs developed a heterogeneous intestinal microflora and possessed abnormal plasma metabolites, indicating that X-SCID could be an immune disorder that affects various in vivo functions. Importantly, the organogenesis of PPs in X-SCID pigs was not promoted by BMT. Although a few isolated lymphoid follicles developed in the small intestine of BMT-treated X-SCID pigs, there was no evidence that they contributed to IgA production and microflora formation. Consistently, most patients with X-SCID who received BMT possessed abnormal intestinal immune and microbial environments regardless of the presence of sufficient serum IgG. CONCLUSIONS: These results indicate that the current BMT therapies for patients with X-SCID may be insufficient to induce the organogenesis of intestinal lymphoid tissues that are associated with numerous functions in vivo.

    Microsatellite markers were developed for the endangered orchid Calanthe izu-insularis (Orchidaceae). This species is unique to the Izu Islands in Japan. Unfortunately, its population size has decreased because of excessive collection for horticultural purposes. In addition, although natural hybridization between C. izu-insularis and C. discolor var. discolor has been reported, morphological differences between C. izu-insularis and the hybridized individuals remain unclear. Using next-generation sequencing, 11 polymorphic microsatellite markers were developed. All developed markers could amplify C. aristulifera and nine markers could amplify C. d. var. discolor, two other orchid species that are also endangered in Japan. The number of alleles and expected heterozygosity at each locus were 1-6 (mean, 2.35) and 0.00-0.79 (mean, 0.30), respectively. These microsatellite markers will help conservation geneticists in their investigation of the proportion of pure C. izu-insularis individuals in the Izu Islands.

    In this study, soil macrofauna in the beds of a full-scale vertical flow constructed wetland were investigated to clarify the effects of vegetation on diversity of soil macrofauna. The investigation was conducted in the vegetative growth stage when plant had a great growth vigor. Because deposits were retained on the surface, macrofauna were investigated only the beds of the first stage. The macrofaunal abundance in vegetated beds was higher than in unvegetated beds, suggesting that vegetation increased macrofaunal diversity. This finding shows that the diversity of vegetation-dependent species generates a different level of diversity in the vegetative growth stage. Though the constructed wetland received rich deposits, i.e. food resources, vegetation affected macrofaunal diversity. Earthworms were most abundant in the 0－10 cm layer of vegetated beds, while their abundance peaked in the 10－20 cm layer of unvegetated beds. These findings may show that importantly, vegetation softens rapid changes in the environment (ex. soil temperature), rather than providing food resources for macrofaunal diversity. It was revealed that plant played an important role on macrofaunal diversity even in the constructed wetland where organic matters were constantly provided from wastewater.

    Cryptosporidium parvum HNJ-1 is widely used as a reference strain in Japan. In the present study, the parasite was subjected for further molecular analysis including transcribed ribosomal region (ITS rRNA), dihydrofolate reductase (DHFR) and surface glycoprotein (GP60) genes. Partial sequence analysis of these genes indicated extensive polymorphism in ITS region compared with relevant sequences of other Cryptosporidium parvum isolates. In addition, this strain was identified as C. parvum IIaA15G2R1 subtype, based on the sequence results of GP60 gene locus.<br>

    Biogeography, an interdisciplinary field drawing on evolutionary ecology, community ecology, and conservation biology, aims to elucidate the processes shaping species distributions from both ecological and historical perspectives. Since the 1990s, biogeography has been advanced by the growth of phylogeography, with its basis in genetic analysis. New analytical tools, including geographic information systems (GIS), climate simulations, and ecological niche modeling (ENM), have brought further innovations. Combining simulations of past or future climates with ENM has allowed the estimation of past or future species distributions. Furthermore, combined analyses using GIS-related tools can reveal the processes of niche differentiation and speciation, and be used to reconstruct the migration histories of biological communities. In this review, we highlight useful analytical tools and data sources and explore their practical applications in biogeography and related fields. Next, we discuss the prospects of biogeography as a more integrated field, combining various data sources such as ancient DNA and the unprecedented amount of genetic data now available from next-generation sequencers.

    More details Close

    The availability of hypervariable microsatellite markers has greatly extended the possibility of parentage analysis in natural plant populations. However, maternity and paternity analysis based on DNA from biparental tissues is often difficult when both parents are unknown and many candidates are available. In this paper, I present a new approach for the identification of the mother trees based on microsatellite analysis of maternal tissues from seeds, fruits, and seedlings. By comparing the maternal genotype with the genotypes of the adult trees, it is possible to unambiguously identify mother trees from the candidates in a population. Because DNA extraction from particular maternal tissues such as woody pericarps is technically complicated, different DNA extraction methods and PCR amplification procedures should be tested on each tissue before performing routine analyses. By choosing the best laboratory procedures based on what tissue is to be analyzed, studying seed dispersal as well as the relative fertility of individual trees in a forest is possible.

    本研究では、本研究代表者らが開発した次世代シーケンシング技術であるMultiplexed ISSR Genotyping by sequencing（MIG-seq）法（Suyama & Matsuki, 2015）を用い、種内レベルの近縁な生物組織の混合試料の構成を明らかにする技術開発を実施している。その第一歩として、2021年度には１）加工食品における混入品種の識別技術開発と、２）古代遺跡の堆積土壌を対象とした古代植生解析のため試料採取を実施した。 加工食品における混入品種の識別に関しては、食用マメの2品種を粉砕して混合し、混合試料を構成する2品種を特定する技術開発を進めた。その前段階として、20品種以上の食用マメから抽出したDNAを用いてMIG-seq法によってDNA品種識別するためのデータを取得した。その結果、ある品種とその突然変異品種と考えられている品種間以外では明瞭に品種識別が可能であることがわかった。そこで、それらの品種の中から2品種を選び、合計4つの組み合わせで2品種のマメを粉砕して混合した模擬混合試料を作成した。この模擬試料を対象としてMIG-seq法による構成品種の特定を試みたところ、それら4つの組み合わせ試料すべてにおいて、混合した2品種を正確に特定することができた。さらに、試験的に市販の加工食品における品種の特定を試みたところ、１つの製品については2品種の構成によって99％以上の配列が説明できることがわかり、少なくとも主要構成品種の特定はほぼ可能であることがわかった。 古代遺跡の堆積土壌を対象とした古代植生解析については、奄美諸島の徳之島に所在する縄文時代からの遺跡発掘に参加し、その堆積土壌から古代DNA分析用の試料を採取した。この分析については極めて困難が予想されるため、今後技術開発を進めていく予定である。

    本年度は、まず、長野県の4つの山域を中心にキツリフネ葉サンプルの採取を行い、MIG-seq法を用いてゲノムワイドなSNPs探索を行い、得られたデータについて集団遺伝解析を行なった。その結果、各山域を単位とする遺伝的なまとまりが検出された一方、開花時期の異なる集団間での遺伝的な構造は認められなかった。加えて、距離による遺伝的隔離の傾向が認められた。これらの結果は、開花時期の集団間変異は山域ごとに独立に生じ、同一山域の集団間では遺伝子流動が維持されていることを示している。ただ、一部の調査地域（松本市、安曇野市）では、距離的に近い2集団の間で遺伝的分化が大きいという現象を見出した。これらの近距離2集団では、開花時期が互いに大きく異なっていた。 次に、東日本各地から採取したウツボグサ葉サンプルについて、MIG-seq法によって探索したSNPsを用いた系統解析を行った。その結果、東日本のウツボグサは大きく二つの系統に分けられた。そのうち長野県のほとんどの集団を含む一系統においては単系統性が支持され、距離による遺伝的隔離の傾向が認められた。しかし、もう一方の系統では北海道と長野県の集団が近縁になるなど地理的に明瞭な遺伝構造が見出されなかった。 最後に、オドリコソウとキバナノヤマオダマキについて、長野県の複数山域で花-訪花者の形態的なサイズマッチングの調査、および集団遺伝解析を行った。まず、両種とも、どの山域でも大型の訪花者が訪れる植物集団は花サイズが大型であり、小型の訪花者が訪れる植物集団は花サイズが小型であった。次に、両種とも、集団間の花サイズの類似度と遺伝的な類似度には関連性がなかった。これらの結果から、花サイズは、地域ごとの平均的な訪花者サイズに適応して山域間で独立に進化していることが示された。

    本年度は、まず、mtDNAのCOII遺伝子系統樹で単一系統であることが確認されているクチナガオオアブラムシ類の1系統において、品種間分化が起こっていることを明らかにした。国内の20地点において、この系統の624個体を採集し、MIG-seq法を用いて得られた334SNPsの情報から系統樹を作成し、寄主植物種および随伴アリ種との対応関係を調べた。その結果、アブラムシは主に随伴アリ種の違いよりも寄主植物種の違いによって、系統内で品種間分化していることが明らかになった。 次に、ヤノクチナガオオアブラムシの口吻長が遺伝形質であるかどうかを明らかにするため、6つのコロニーから合計265個体を採取し、MIG-seq法を用いて得られた251SNPsを元にクローン解析を行った。その結果、アブラムシをコロニー内でクローンを識別することはできなかった。この原因は今後の課題となる。 最後に、アリが口吻のより短いヤノクチナガオオアブラムを選択的に捕食しているかどうかを明らかにするため、野外観察と形態計測を行った。まず、口吻が長い幼虫個体ほど多くの師管液を吸汁することができ、それに伴ってより多くの甘露を排泄することを明らかにした。次に、アリが口吻の短いアブラムシを選択的に捕食しているかどうかを明らかにすることを目的として野外調査を行った。松本市内において3つのヤノクチナガオオアブラムシコロニーを用いて、アリに捕食されているアブラムシと捕食されていないアブラムシを採取した。その後、各サンプルの口吻長と、体サイズの指標として頭幅、触角長、中後脚のふ節長を測定した。その結果、アリが体サイズに対して口吻長の短いアブラムシを選択的に捕食する場合があることが明らかになった。

    ニワトリ（鶏）の免疫学に関する教科書には、骨髄で造血幹細胞から分化したB細胞前駆細胞は、排泄腔近傍に存在するファブリキウス嚢でB細胞へと分化し、その後、脾臓やパイエル板（回腸終末部）、盲腸扁桃（盲腸基部）といった免疫臓器で機能すると記載されている（Avian Immunology 2nd Edition）。一方で、我々は、広大な表面積を有する盲腸にも成熟したB細胞が多数集積する濾胞構造が広範囲に発達していることを見出し、盲腸扁桃やパイエル板とは異なる、腸管に発達する新たな免疫臓器（Cecal patches: CP）の存在を明らかにしてきた。加えて、経時的に実施した形態学的解析を通して、CPは盲腸扁桃と同様に孵化後に形態形成されること、腸管の免疫機能に深く関わるIgA（免疫グロブリンのサブクラスの１つ）を産生する形質細胞へのB細胞からの最終分化が、盲腸扁桃やパイエル板以上に、CPで盛んに行われていることを見出し、既存の教科書には記載されていない、孵化後の鶏の腸管内で発達するCPを中心とした粘膜免疫システムの存在を提唱してきた。 <BR> そこで本研究では、孵化1, 2, 3, 5, 7 週間後の肉用鶏（Ross308系）より、盲腸を採材・固定し、CPの形態形成を組織学的に解析した。また、組織切片をIgM, IgA, IgYをマーカーとした免疫組織化学染色に供することで、抗体産生細胞の局在変化も比較解析した。その結果、CP形成が開始される時期は、盲腸扁桃の発達時期よりも少し遅く、孵化2週齢以降であることが明らかになった。このことは、盲腸扁桃とCPの形態形成を促す刺激は異なっている可能性を強く示唆していた。さらには、CPで濾胞構造が発達する時期は3週齢前後であり、同時期に濾胞内でB細胞からIgA産生細胞への最終分化が起きていることも明らかになった。

    To determine whether stem cell genomes are maintained stably in long-lived organisms, they generated a high-quality genome of Shorea laevis and detected somatic mutations that accumulated over 400 years to accurately estimate the mutation rate prior to natural selection and genetic drift in the next generation population. The number of somatic mutations was shown to increase linearly with growth, and the rate of de novo mutations per base per year was accurately estimated. Detailed analysis of the mutation spectrum showed that mutations caused by DNA damage to UV light were the most abundant (53.1%). Comparative genomic analysis suggested that trees have a higher copy number of poly(ADP-ribose) polymerase (PARP) than perennial and annual plants, contributing to their long-term survival and protection from DNA damage and pathogen infection. These results provide important knowledge in understanding the evolution of DNA repair and lifespan in plants.

    In this study, we conducted a field survey on flora, environmental factors, and plant functional traits (e.g., leaf area and weight, chemical composition) in moorlands widely distributed across the Hakkoda Mountain range in Aomori Prefecture. We established a species distribution model based on relationships between species spatial distribution and environmental factors, and performed an area reduction simulation based on the actual pattern of moorland area reduction from the past (1967) to the present (2019). The result suggests that the loss of species with area reduction does not exhibit a proportional relationship, and that there might be differences in the pattern of diversity change among the focal moorlands. In addition, species diversity of moorland plants depended on how many moorlands existed around the focal moorlands in the past, suggesting that current plant diversity in moorlands is strongly shaped by the past landscape.

    全国のスギ天然林由来の挿し木苗が集植されている茨城県千代田苗畑において、生体防御物質の測定を行った。スギ天然林の４つの遺伝グループが含まれる６集団（鯵ヶ沢（日本海側北部）、山之内、安蔵寺（日本海側南部）、河津、新宮（太平洋側）、屋久島）の計56クローンを解析対象とした。 テルペノイド測定用のサンプルを８月に採取し、ヘキサンを溶媒としたメスアップ法によりテルペノイドの抽出を行い、ガスクロマトグラフィーによりジテルペン類の分析を行った。その結果、日本海側系統の北部ならびに屋久島においてジテルペンの量と種類において特徴的な違いが認められた。また、未同定の成分も検出され、スギ針葉内には地域により成分の種類ならびに量に地理的変異があることが示された。 また、カロテノイドの測定では、光ストレスの程度の把握が必要となるため、まず遺伝グループを代表する３集団に対して、8月と11月に光合成速度の測定を行った。その結果、太平洋側系統である新宮集団においてのみ、11月まで光合成速度が低下しないことが明らかとなった。このことは、試験地のある太平洋側環境下では、太平洋側系統の個体のみ遅くまで光合成を行っていることを示しており、光合成能力に関して、環境への適応が起こっていることが示唆された。また、カロテノイド測定用に夏季、秋季、冬季の３回にわたり針葉を採取し、液体クロマトグラフィー分析に供試した。 上記防御物質の測定対象個体に対し制限酵素断片配列の網羅的解析（ddRAD）を用い、ゲノムワイドなDNA多型情報を取得した。その結果、5000座を超える遺伝子座のDNA変異を特定した。また、他種において上記成分の合成に関わると予想される候補遺伝子のスギの相同遺伝子を特定し、61遺伝子座のDNA解析用のプライマーを設計した。

    Tropical forests in Southeast Asia are known as one of the global centers of species richness, and also as the area where forest loss is most rapid. However, it remains uncertain how many species of vascular plants are there. Therefore, we conducted a new method of molecular phylogenetic analysis for more than 10,000 vascular plant species collected from more than 100 research plots in Southeast Asia. Consequently, we discovered more than 100 new species and newly recorded species in several countries.

    In contrast to the clump-forming tropical bamboos, temperate bamboos in East Asia can extend horizontally via long rhizomes. We verified the effects of such characteristics of the temperate bamboos on their regeneration process after mass flowering in the heterogeneous environments of the forest understory. Bamboo populations in the dark conditions under the canopy trees grew very slowly during the first 10 years after germination, but after then, recovered rapidly. It was caused by the invasion of the well-grown clones from the canopy gaps by horizontal rhizome extension. Our results indicated the importance of the mode of clonal growth of bamboos on the regeneration process after mass flowering and death.

    Repeated collisions between oceanic islands and mainland Japan, through movement of tectonic plates, have generated a biodiversity hotspot in Japan. As the plate continued to move, these islands collided with the main Japanese islands. This proposes a biogeographic scenario that, in the past, mainland species colonized newly forming volcanic islands and then underwent independent processes of community assembly, adaptive evolution, and speciation. When this volcanic arc collided with the mainland, these island-adapted species came into contact with their mainland evolutionary cousins. We reported a review of the published population phylogenies of plant taxa. We formulate the hypothesis that the pattern of repeated secondary contact of mainland and island sister species, and their subsequent interactions, have generated a biodiversity hotspot in Japan.

    The objectives of this research are to clarify the mechanism underlying decreasing body weight and feed efficiency in broiler chickens exposed to heat stress, and to develop feed ingredients to improve the reduced performance. Heat exposure to chickens was found to induce increased proteolysis of skeletal muscles via more mitochondrial ROS generation and decreased CD3-positive cell in the spleen so that metabolic and immune systems remarkably enhance energy requirement to maintain homeostasis. Streptococcus appears to be the less dominant genus in the ileum of heat-stressed chickens. Feeding diets supplemented with cashew nut shell liquid (CNSL) causes broiler chicken to alleviate reductions of body weight and feed intake when exposed to heat, partially via control of intestinal immune-related gene expression.

    Studies of the genetic origin of hybrids are required to clarify systematic relationships in many species groups. However, it is generally difficult to develop common DNA markers among different species for the genetic analysis. Here, we conducted a new approach, multiplexed ISSR genotyping by sequencing (MIG-seq) method, for identifying the parental species of two putative hybrid species (groups) of dwarf bamboo and Rhododendron. Our population genetic analysis strongly suggested hybrid origin of the species. This approach can be applied to investigating a wide range of hybrid species, and will be able to contribute to systematic studies of many species.

    In order to clarify the current situation of biodiversity in New Caledonia, we carried out conservation genomics analysis for semi-endemic genus Oxera (Lamiaceae) which consists of ca. 30 species with distinct traits in their morphology and ecology. By analyzing transcriptomes obtained from RNA-seq, we inferred several candidate loci that may be involved in speciation and environmental adaptation. In order to construct effective conservation measures, phylogeny of species, genetic differentiation between intraspecies populations, effective population sizes, demographic histories were inferred based on constructed genomic information for exhaustively collected samples of Oxera species and populations.

    We tried to get genome-wide SNPs using modified GBS and developed new method to estimate the longevity. We used 24 leaves of Sasa kurilensis in Towada, whose longevity has already identified by flowering interval (18years old: each 4 ramets of 2 genet and 8 ramets of 1genet , 80years old: 8 ramets of 1genet). We found no difference in numbers of SNPs among new and old individuals. However, we found the diversity of SNPs was higher in old individuals than in younger ones. It suggested that information from SNPs using NGS might be useful to estimate longevity.

    The effect of radiation exposure on mutation rates is little known, especially for low doses and in situ conditions. In this study, correlations with air dose levels and DNA mutation rates were evaluated using Next Generation Sequencer for the clonal plant, Phyllostachys edulis. We collected 94 samples of Phyllostachys edulis from 14 sites with air dose rates from 0.04～7.80μSv/h. Their clonal identity was confirmed by analysis using microsatellite markers, and then, sequences among samples were compared by MIG sequence. The sequence data were obtained from 2,718 loci. In these sequences, 442 loci showed polymorphism patterns including recent origin mutation, old mutation, and sequence errors. The number of mutations per sample ranged from 0 to 13, and did not correlate with air dose levels. This result indicated that DNA mutations have not accumulated in Phyllostachys edulis living in the air doses levels less than 10μSv/h.

Then we applied these methods to pollen samples found in a glacier.

    Leaf and flower tissues were collected from the different branches of Japanese oak and maple of more than 100 years old using the Tomakomai Experimental Forest canopy observation crane system at Hokkaido University. The age of each branche was estimated by tree ring observation using fallen trees in Uryu Experimental Forest of Hokkaido University. Total DNA was extracted from each sample and genome sequence data of more than 100,000 bases at 1500 locus was obtained using the next generation sequencers installed in Tohoku University. Based on these sequence data, we found at least two mutations per the same individual. These mutations were carried over to new branches, implying the coexistence of cells with different genetic composition within an individual.

    We developed a quick method to construct linkage maps with pollen DNA using next-generation sequencer (NGS). As one of the applicable techniques in this study, we developed a PCR-based procedure to construct reduced representation libraries, representing de novo single nucleotide polymorphism (SNP) discovery, and its genotyping using NGS. We then demonstrated the applicability of the method in pollen DNA analysis. Mendelian 1:1 segregation in haploid pollen grains from one individual plant was demonstrated for 226 SNP markers discovered by the method. We concluded that this approach is applicable to construct linkage maps in non-model plant species.

    Using Next Generation Sequencer, we analyzed genetic backgrounds of evolutionary changes between two pairs of sister species with contrasting adaptive strategies: Hemerocallis fulva and H. citrina having swallowtail-pollinated red flowers and hawkmoth-pollinated yellow flowers, and Rubus palmaus and R. grayanus having deciduous and evergreen leaves. In the Hemerocallis pair, we identified a group of genes of Anthocyanin color-pigments biosynthesis in which expression levels are correlated with the amounts of Anthocyanin color-pigments. This finding supported that changes in a regulatory system of Anthocyanin biosynthesis caused the evolution of flower color. In the Rubus pair, we found that a gene suppressing the receptor of red light (phytochrome) is highly differentiated between species. This finding suggests that divergence of evergreen/deciduous leaves were driven by regulatory changes of a light receptor.

    Bamboos in the temperate regions of the northern hemisphere are well known to have conspicuously long interfloral periods. To clarify the evolutionary trends of bamboo flowering behavior, we proposed the new insight by taking their genet-intermingled structure into account. In contrast with clump-forming tropical bamboos, temperate bamboos form genet-intermingled structure with horizontal extending rhizomes. We clarified that the large genets of the temperate bamboo after long clonal growth showed high reproductive success with low self-fertilization rate. Theoretical study also supported that the long rhizomes drive the evolution of delayed flowering. These studies strongly suggested the importance of genet spatial structure on the evolution of bamboo flowering behavior.

    In a temperate forest, we found clear evidences that both negative-feedback with pathogenic fungi and positive-feedback with mycorrhizal fungi strongly determine the seedling performance and consequent species-diversity. In shaded forest understory, host-specific pathogens caused seedling death particularly for conspecifics,increasing species-diversity. In contrast, the host-specific mycorrhizal fungi facilitated seedling performance particularly for conspecifics in gaps, decreasing the diversity. In artificial conifer forests of different species diversity, we revealed that both the ecosystem functions (i.e. ) increased with increasing the species diversity.

    Laurel forests dominating pristine lowlands in western Japan are considered to have expanded their distribution from one or more refugia after the last glacial maximum. In this project, we investigated their evolution during and after the expansion by studying genetic structure of their representative species, Distylium racemosum, Cleyera japonica, and Zanthoxylum ailanthoides, along with Taxodium distichum that grows in wetlands of North America. We obtained some indications that the three laurel forest species, although growing in the same forest at present, had different population histories. Also we found a small number of candidate genes that might have contributed to the adaptation.

    We developed a method for DNA analysis of ancient pollen from lake sediments and glaciers to retrieve genetic information for past spatial dynamics of intra- and/or inter-specific lineage. We reported genetic analysis of fossil pollen collected from lake sediment in central Norway and showed that conifer trees survived in ice-free refugia of Scandinavia during the last glaciation. And we compared DNA- and pollen-based vegetation analysis of the lake sediment samples. We also reported DNA analysis of Pinus pollen grains collected from Belukha glacier in Russia and identified them at the section level in the genus. These results have major implications for plant phylogeography by allowing direct analysis of past genetic information in ancient pollen.

    The dense growth of dwarf bamboo creates shade stress against tree regeneration. How can dwarf bamboo grow under deep shade in the understory? To analyze the relations between light conditions and biomass or the growth characteristics of S. palmata, we investigated the canopy-open- ness and biomass at the belt transects set up in the gap-understory continuum. We also analyzed whether the biomass was dependent on light intensity or the distance from the gap. Canopy-openness showed a pattern dependent on the distance from the gap. The biomass peaked at the gap and gradually decreased up to the edges of the gap, while it remained constant in the understory. The biomass did not depend on light intensity. This phenomenon can mainly be interpreted two ways. One is that dwarf bamboo is a shade-tolerant species, and adapts to a low light environment due to its growth characteristics. The second is that S. palmata is subject to physiological integration. The result may indicate that physiological integration among ramets enables a compensatory growth through photoassimilate with connected neighboring ramets.

    We showed that flowering time and flower color of Hemerocallis fulva ; Pollination by swallowtail butterflies and H. citrina ; Pollination by hawkmoths were regulated by major loci using segregation of F2 hybrids. We successful for genotyping individual pollen grains, thus we showed that swallowtail butterflies preferentially visited reddish flowers and hawkmoths preferentially visited yellowish flowers. We evaluated the possibility of the evolution by simulation using our genetic and experimental data. We found that flowering time having pleiotropic effects both on natural selection and assortative mating, and promote evolution of H. citrina from H. fulva.

    In the area the bamboo(Melocanna baccifera) flowered gregariously and died in Mizoram, India, recovery process was monitored by the research of vegetation surveys and the DNA analysis. In addition, trials of extraction of the flowering area in a broad scale, a discussion of the relationship between productivity of shifting cultivation agriculture and flowering timing, the change of rodent population, were done. Through the broad area research using satellite images the flowering of this species occurred in waves for several years in its distributing area. The practice of shifting cultivation agriculture influences good results for the recovery of this species in many cases. The change of rodent population converged in a few years after flowering.

    Biodiversity loss has important consequences for a variety of ecosystem processes. We manipulated genotypic richness of the common reed, Phragmites austraslis, in a small-scale experimental system similar to constructed wetlands. Genotypic richness increased plant primary productivity, and this effect was largely explained by niche complementarity among genotypes. Nitrogen loss decreased as genotypic richness increased. Given that water purification through nitrogen removal is achieved by plants and microorganisms around the plant root zone, these results suggest that genetic diversity enhanced water purification possibly by both increased plant productivity and bacterial activity.

    Sasa, the dwarf bamboos, are long-lived monocarpic plants with vigorous rhizomatous vegetative reproduction for over 100 years. They often flower simultaneously in a wide range. It is a substantial question why bamboos flower to die simultaneously in a wide range although they can keep exclusive dominant populations with vegetative reproduction for a long period. In this research, we discussed the evolutionary trends of bamboo flowering habits from the viewpoint of genetic diversity, by analyzing the genetic structure of Sasa populations before and after mass flowering.

    As needs of human society to forest ecosystem diversifying, planting of broad-leaved trees is now increasing. Currently, there are no rules regarding the seed transfer of broad-leaved trees. It is crucial to use appropriate planting stocks to achieve conservation of adaptive genetic variation that harbored in each of different regions, avoiding the risks of genetic disturbance. Fagus crenata as targeted species, we identified DNA polymorphisms on chloroplast genome, and developed SNP markers. 4,321 samples were collected from 698 locations covering almost whole range of F. crenata, and surveyed 18 SNPs at three regions in the large single copy region of the chloroplast genome, and determined their haplotype. We investigated relationship of chloroplast haplotypes, and constructed fine haplotype map.

    Prediction of bamboo flowering has been difficult because of its long flowering periodicity. It causes the ecological research only just after the flowering and it was impossible to understand its behavior before the flowering. Nevertheless, by the intimate analysis of the past flowering records, results of preliminary research and the interview to farmers, I could rather correctly predict the flowering periodicity of bamboo (Melocanna baccikra) called Muli Bamboo in Bengali. This species distributes from eastern part of Bangladesh to western part of Myanmar including north-east India.. One of the centers of this species distribution is Mizoram in India. In this area one of the main agriculture systems is slash-and-burned. It is thought that this species has expanded its distribution area by the burning of farmers. Through the analysis the flowering periodicity of this species has been predicted as 48 years and the coming gregarious flowering was expected in 2006-2007. In 2005 we set up two research site in Mizoram. One was for an ecological research in Sairang and another one for an agricultural research in Mamit. In both sites Melocanna baccikra started to flower as predicted in the autumn of 2006 and fruited on the following year. As a result, we got a lot of knowledge about bamboo flowering. As already has been noticed as an experience the quantity and quality of new bamboo calms on the flowering year was very low. We also observed the flowering on the one year before and after the gregarious flowering. As the molecular ecological research we conducted DNA analysis using leaf samples and made a clone map. Through the inspection of this clone map it was clear that these small scale flowering does not occur by the DNA groups. Inflorescence was classified to two types. One type has a function like male flower and another androgynous. Bamboo seeds were very large and 20-50 seeds were produced on each culm. Through the observation we could understand all the process of flowering and fruiting. Addition to these results we also got some ecological knowledge about the rodents population. It started to increase just after fruiting. Concerning to the relationship between bamboo flowering and slash-and-burned agriculture, the necessity of understanding of flowering periodicity was indicated to keep the high productivity. These knowledge in detail concerning to bamboo flowering are regarded as the first records in the world.

    1. Analysis of the mechanisms of species-diversity in temperate deciduous broad-leaved forests. To investigate the relative importance of several biotic and abiotic environmental factors in determining species diversity, we investigated number of tree species, nutrient and water contents, light, coverage of understory vegetation (e.g., shrubs, dwarf bamboo), depth of leaf litter, and distance from conspecific adults in each of 600 individual quadrats (10 m x 10m) in a 6ha plot. In the analysis of sequential equation model (SEM), we found that distance of conspecific adult had a strong effects on abundance and diversity of tree species in seedling stage, but the effect decreased with increasing plant size. For saplings, the abundance was strongly affected by the abiotic factor such as nitrogen contents, light level and water availability. We also analyzed the causes of distance-dependent mortality of tree seedlings for 8 tree species in a hardwood forests by sowing thei seeds at two distances (i.e. far and near from conspecific adults). In the six of the eight species studied, we found distance and/or density-dependent seedling mortality which was mainly caused by pathogenic fungi. In the analysis of pathogenic fungi, we observed speies-preference, which preferentially attack conspecific seedlings compared to hetero-specific seedlings in Prunus grayana. 2. Analysis of the recovery mechanisms of species diversity in coniferous plantation and the restoration programs. In the Criptomeria japonica plantation, heavy-thinning (67% of total basal area) had a greater effects on species diversity rather than light-thinning (33%). Distance from neibouring hardwood forests also strong effects on the species diversity.

    The pollination process of tree species are important for the maintenance and regeneration of tree communities, and the genetic traits of pollen grains that are transported to flowers influence the reproduction and fitness of plants. Despite the importance of insect-pollination systems, understanding of those systems is still larking due to the absence of the genetic analysis of pollen grains. We extracted haploid nuclear DNA from a single pollen grain by using a simple pollen DNA extraction method. Multiple microsatellite genotypes of a single pollen, which are useful for ecological studies, e. g. pollen dispersal pattern, paternity analysis and evaluation of pollinators, were determined simultaneously within a single reaction tube. Using nine pairs of microsatellite primers, more than 90% of genotypes were successfully determined. Using the method developed for the present research, we evaluated the pollination efficiencies of bumblebees, flower beetles that visited the flowers of Magnolia obovata. Most of the pollen adhering to bumblebees was self-pollen. This result suggests that visitation by the insects may cause geitonogamous pollen flow and negatively affect the reproduction of M. obovata, causing inbreeding depression. In contrast, flower beetles transported large amounts of genetically diverse outcross pollen. The present results suggest that certain beetle species contribute to the pollination of M. obovata quantitatively and quantitatively. Direct gentic analysis of pollen grains will advance the understanding of plant mating systems, and may shed light on the mutualism and co-evolution of trees and flower visitors.

    The present study aimed to clarify how long does it take from seedling emergence to the full recovery of Sasa population after mass flowering, with special reference to the clone dynamics in the regeneration process. Mass flowering and death of Sasa population is known to be an important episodic event in the forest vegetation dynamics in Japan. Our research sites are as follows : 1) Togakushi (Nagano Pref.) ; Sasa kurilensis flowered in 1974. 2) Hakkoda (Aomori Pref. ) ; S. kurilensis flowered in 1979, 3) Towada (Akita Pref.) ; S. kurilensis flowered in 1995, and 4) Oomi (Kyoto Pref) S.veitchii var. firsuta flowered in 2007. Main results are as follows : 1) Isolation and characterization of microsatellite loci for several Sasa species, and analyzing of clonal structures of Sasa populations in the regeneration process. 2) Exploitation of a demographic research method for clarifying the clone dynamics during the regeneration process. We studied the dynamics of Sasa juvenile population with DNA analysis and clarified that the self-thinning process had been continued even in the 20-year old S. kurilensis juvenile population. So, it confirmed that it takes more than 20 years from seedling emergence to the full recovery of Sasa population after mass flowering. 3) The changes in clonal structures during the regeneration process. By the research in a 10-years old juvenile population and the non-flowered full size stage population for S. kurilensis in Towada Site, we found that the growth of Sasa juveniles were affected by the light conditions determined by the canopy conditions and that the full-sized S. kurilensis population was composed with the very large clones, up to 2500 m^2. During the regeneration process, a few large genets grown in the good light cognitions like canopy gaps are presumed to become dominant in the future.

    スウェーデン中部の湖から得られた湖底堆積物を材料として、異なる2時代(約100年前と10000年前)の堆積層からマツ属花粉を収集し、これらの花粉化石を試料としてDNA分析を行った。この分析によって、異なる時代に成立したヨーロッパアカマツ集団を対象とした遺伝的組成の比較が可能になる。つまり、過去の森林について遺伝的多様性や遺伝的構造に関する情報を解析し、森林植生変遷史に遺伝学的な情報を盛り込むことができる。 葉緑体DNA上のマイクロサテライト領域を含む約220塩基の領域を対象として、約100年前の試料500粒についてDNAの増幅を試みたところ、そのうち7粒から塩基配列データが得られた。また、約1万年前の試料301粒のうち4粒から得られ、合計11粒の花粉化石から塩基配列データが得られた。同様に約105塩基の領域について増幅を試みたところ、約100年前の試料234粒のうち4粒から、約1万年前の試料408粒のうち5粒から、合計9粒の花粉化石から塩基配列データが得られた。また、湖底堆積物を得た湖の周囲に現在生育しているヨーロッパアカマツ30個体を材料として、220塩基の領域についてのハプロタイプを調べた。 得られた配列は多型性に富んでおり、約220塩基の領域については16種類、約105塩基の領域については7種類のハプロタイプが検出された。現生のサンプルを合わせて解析した約220塩基の領域については、現生・100年前・1万年前で共通のハプロタイプが検出されたことから、後氷期を通じて調査対象地である湖の周辺で同じ系統が生き延びたことを示唆するものと考えられる。 本研究により、花粉化石のDNA分析が可能であることが示されただけでなく、植物集団の時・空間的な動態について、遺伝的データが直接得られることが示されたと言える。

    In this Study, we examined a molecular marker diagnosis as effective method to discriminate of Arbuscular Mycorrhizal Fungi (AMY) species. And on the basis of the method, geographic variation of AMF community structures in Japanese grassland and soil factors affecting on those are studied. New PCR primer was designed for specific amplification of a part of 18S rDNA of arbuscular mycorrhizal fungi. The PCR-DGGE with this primer enabled to discriminate 5 AMF species including Archaeospora leptoticha, whose 18S rDNA had not be amplified with other AMF specific primers reported previously. Thus, the new PCR-DGGE analysis method as an effective way to analyze AMF community structure in fields were developed. Miscanthus sinensis and Zoysia japonica were collected from 9 grasslands in Japan. Sampling sites were chosen from different soil environment grasslands : allophenic andosoil, non-allophenic andosoil and yellow soil. PCR-DGGE was performed and the phylogenetic tree was made to decide the base sequence of these prominent DGGE bands. Prominent DGGE bands of DNAs in sampled plants were belonged to Glomus-Ab, Ac, and Ad group and little to Glomus-B-group and Acaulosporaceae. Concerning soil types, Glomus-Ab group was distributed over both soil types in all grassland, but Glomus-Ac, Ad group were shown different tendency among soil types and host plants. Spore communities in root rhizoshere were dominant with Glomus rubiforme, Acaulospora koskei and so on unlike fungal species in mycorrhiza. Using sown white clover grassland, factors effecting AMF community structures were examined. In mature community of grassland, Glomus-Ab, Ad, B group and Acaulosporaceae were mainly colonized, but in newly plowed grassland, Glomus-B group and Acaulosporaceae. Additionally, high levelof available phosphate in soil caused a restraint to diversification of colonized AMF species.

    To evaluate the mechanisms of bio-diversity of riverside forests, we investigated the reproductive strategies and mating systems of several dominant tree species in several well-preserved riverside forests in temperate region of Japan. In the dioecious tree species, Salix sp., we revealed the relative importance of sexual and asexal reproduction in relation to stand ages. In Salix sp., female invest much more resource to reproduction, but they have several superior physiological, morphological, and phenological mechanisms to compensate the reproductive cost. We also revealed that a riverside species, Jugalns ailanthifolia, is a heterodichogamous species, which have two type of flowering phenolgies. Both types invest equally to each of male and female function. Male reproductive success was also almost identical to that of females. We revealed the food chain from litter fall in mountaneous river side forest to fish in sea by using stable isotope. This study provide the evidences of importance of the preservation of natural riverside forests to maintain the bio-diversity.

    Clone dynamics of a dwarf bamboo, Sasa kurilensis was investigated during the regeneration process after mass flowering and death. Sasa spp. Were monocarpic long-lived clonal plants with mass flowering habits. The aim of this study is to clarify the long-term dynamics of genetic diversity in Sasa populations through their life cycles. 1. We carried out DNA analysis for the flowered population of Sasa kurilensis, and clarified that mass flowering was caused by the simultaneous flowering of many different genets. 2. We estimated the clone structure of the 21-year old S. kurilensis population with 1) the DNA fingerprint method (AFLP) and 2) the dig-up method. Although the population size of S. kurilensis has been nearly recovered, genet sizes in the population were widely varied. Severe inter-genet competition had continued and caused the self thinning process. S. kurilensis population has not attained stable states in 20 years after germination and it needs fairly long time to gain the stable states. We concluded that : 1) AFLP fingerprint method is a strong tool for the analysis of the genet dynamics of clonal plants : 2) The simultaneous flowering considerably enhanced the genetic diversity of Sasa population : 3) Clonal structure widely changed during the life cycle process of Sasa. Through this study, we found that the combined research method with the demographical study and molecular ecological techniques makes the direct observation of genet dynamics possible, which improve further understanding of long-term dynamics in the clonal plant populations.

    本研究ではマツ科樹木の化石花粉を対象として、化石花粉中DNAのPCR増幅および塩基配列分析を行った。前年度の研究において1065粒中14粒の化石花粉について目的部位のDNA増幅が見られ、これらのサンプルについてその塩基配列を調べた。しかしながら、本年度にそれらの塩基配列を詳細に検討した結果、少なくとも一部のサンプルについては現生花粉の混入による増幅であると結論づけざるを得なかった。この結果を重大に受けとめ、すべての分析手順を見直した。その結果、コンタミネーションの原因を特定することができ、本分析手法の改善を行うことができた。そこで、新しい手法に従ってあらためて化石花粉からのDNA増幅を試みた。材料として、3カ所の湿原堆積物、深層湖底堆積物および表層湖底堆積物の様々な層から採取した化石花粉を用いた。合計840粒の化石花粉についてDNA増幅を試みたが、すべてのサンプルで増幅は見られなかった。すなわち、今回分析に用いた化石花粉についてはDNAの保存性が極めて低いと考えられた。そこで化石花粉内部の保存性を左右する堆積条件等について検討し、化石花粉中のDNA分析に適した材料の条件を推定した。現在、現段階でこの分析に最も適したと考えられる材料を用いてDNA増幅を試みている。 本研究の補助金交付期間内では、残念ながら最終目的である「古植生の復元」までたどり着くことはできなかったが、目的の一つであった「分析方法の確立」については大きな成果が得られた。これらの成果をふまえ、今後も研究を継続する予定である。
