    Field measurement of CO2 assimilation rate in plant leaves is done by clumping the leaf with a chamber and waiting a few minutes for each measurement using special carry on equipment. This costly and labor-intensive method has hindered the acquisition of large-scale data on photosynthesis of field grown plants. We created MIC-100, a new closed-type photosynthesis measurement device with a novel infrared gas analyzer cell that enables high-throughput measurement of leaf CO2 assimilation rate. The measurement time required for a single leaf using MIC-100 was reduced to one-seventh that of conventional open system devices, while similar values were obtained for the same leaf under high-light conditions. We also created two supporting technologies to obtain rapid photosynthesis measurements for field-grown rice: the upper-limb assist suit and the leaf area measurement system with a commercial document scanner. These systems enabled large-scale surveys of the natural genetic variation and ontogenetic changes among diverse sets of rice accessions. MIC-100 and the related systems will be useful for physiological studies with many other plant species and for growth surveys in the agricultural fields.

    <title>Abstract</title>Symbiosis between organisms influences their evolution via adaptive changes in genome architectures. Immunity of soybean carrying the <italic>Rj2</italic> allele is triggered by NopP (type III secretion system [T3SS]-dependent effector), encoded by symbiosis island A (SymA) in <italic>B. diazoefficiens</italic> USDA122. This immunity was overcome by many mutants with large SymA deletions that encompassed T3SS (<italic>rhc</italic>) and N2 fixation (<italic>nif</italic>) genes and were bounded by insertion sequence (IS) copies in direct orientation, indicating homologous recombination between ISs. Similar deletion events were observed in <italic>B. diazoefficiens</italic> USDA110 and <italic>B. japonicum</italic> J5. When we cultured a USDA122 strain with a marker gene <italic>sacB</italic> inserted into the <italic>rhc</italic> gene cluster, most sucrose-resistant mutants had deletions in <italic>nif</italic>/<italic>rhc</italic> gene clusters, similar to the mutants above. Some deletion mutants were unique to the <italic>sacB</italic> system and showed lower competitive nodulation capability, indicating that IS-mediated deletions occurred during free-living growth and the host plants selected the mutants. Among 63 natural bradyrhizobial isolates, 2 possessed long duplications (261–357 kb) harboring <italic>nif</italic>/<italic>rhc</italic> gene clusters between IS copies in direct orientation via homologous recombination. Therefore, the structures of symbiosis islands are in a state of flux via IS-mediated duplications and deletions during rhizobial saprophytic growth, and host plants select mutualistic variants from the resultant pools of rhizobial populations. Our results demonstrate that homologous recombination between direct IS copies provides a natural mechanism generating deletions and duplications on symbiosis islands.

    <title>Abstract</title>Leaf photosynthetic rate changes across the growing season as crop plants age. Most studies of leaf photosynthesis focus on a specific growth stage, leaving the question of which pattern of photosynthetic dynamics maximizes crop productivity unanswered. Here we obtained high-frequency data of canopy leaf CO2 assimilation rate (<italic>A</italic>) of two elite rice (<italic>Oryza sativa</italic>) cultivars and 76 inbred lines across the whole growing season. The integrated <italic>A</italic> value after heading was positively associated with crop growth rate (CGR) from heading to harvest, but that before heading was not. A curve-smoothing analysis of <italic>A</italic> after heading showed that accumulated <italic>A</italic> at &gt; 80% of its maximum (<italic>A</italic>80) was positively correlated with CGR in analyses of all lines mixed and of lines grouped by genetic background, while the maximum <italic>A</italic> and accumulated <italic>A</italic> at ≤ 80% were less strongly correlated with CGR. We also found a genomic region (~ 12.2 Mb) that may enhance both <italic>A</italic>80 and aboveground biomass at harvest. We propose that maintaining a high <italic>A</italic> after heading, rather than having high maximum <italic>A</italic>, is a potential target for enhancing rice biomass accumulation.

  12. Potential of rice landraces with strong culms as genetic resources for improving lodging resistance against super typhoons. International-journal

    It is generally believed that rice landraces with long culms are susceptible to lodging, and have not been utilized for breeding to improve lodging resistance. However, little is known about the structural culm strength of landraces and their beneficial genetic loci. Therefore, in this study, genome-wide association studies (GWAS) were performed using a rice population panel including Japanese rice landraces to identify beneficial loci associated with strong culms. As a result, the landraces were found to have higher structural culm strength and greater diversity than the breeding varieties. Genetic loci associated with strong culms were identified, and it was demonstrated that haplotypes with positive effects of those loci were present in a high proportion of these landraces. These results indicated that the utilization of the strong culm-associated loci present in Japanese rice landraces may further improve the lodging resistance of modern breeding varieties that have relied on semi-dwarfism.

    <title>Abstract</title> How genetic variations affect gene expression dynamics of field-grown plants remains unclear. Expression quantitative trait loci (eQTL) analysis is frequently used to find genomic regions underlying gene expression polymorphisms. This approach requires transcriptome data for the complete set of the QTL mapping population under the given conditions. Therefore, only a limited range of environmental conditions is covered by a conventional eQTL analysis. We sampled sparse time-series of field-grown rice from chromosome segment substitution lines (CSSLs) and conducted RNA-sequencing (RNA-Seq). Then, by using statistical analysis integrating meteorological data and the RNA-Seq data, we identified 1675 expression quantitative trait loci (eQTLs) leading to polymorphisms in expression dynamics under field conditions. A genomic region on chromosome 11 influences the expression of several defense-related genes in a time-of-day- and scaled-age-dependent manner. This includes the eQTLs that possibly influence the time-of-day- and scaled-age-dependent differences in the innate immunity between Koshihikari and Takanari. Based on the eQTL and meteorological data, we successfully predicted gene expression under environments different from training environments, and in rice cultivars with more complex genotypes than the CSSLs. Our novel approach of eQTL identification facilitated the understanding of the genetic architecture of expression dynamics under field conditions, which is difficult to assess by conventional eQTL studies. The prediction of expression based on eQTLs and environmental information would contribute to the understanding of plant traits under diverse field conditions. (224/250 words)
