title: Effect of pericarp removal on buckwheat seed respiration and germination under submerged conditions

description: Excessive soil moisture (ESM) is a critical factor limiting the productivity of buckwheat (<i>Fagopyrum esculentum</i> Moench) because ESM inhibits its germination. This study investigated the effects of pericarp and seed respiration on reduced buckwheat germination caused by submergence. Seeds were submerged prior to germination testing under aerobic conditions. The effects of days of submergence treatment and pericarp removal on germination percentage were significant. The germination percentage in the 3-day submergence treatment was low in seeds with pericarp (P+) but was significantly improved in seeds without pericarp (P−). Pericarp removal also improved the germination percentage of non-submerged seeds. Pericarp thickness and pericarp/seed dry weight ratio (PWR) were not significantly correlated with the germination percentage in 3-day submerged P+. However, both were significantly negatively correlated with the germination percentage in 1-day submerged P+. Seed respiration rate in water, measured on seeds not submerged before measurement, was significantly higher in P− than in P+; that of P− increased with time, while that of P+ showed a decreasing trend with time beyond the first 24 h. Seed respiration rate during the first 24 h was significantly negatively correlated with germination percentage in 3-day submerged P+. A negative influence of pericarp thickness and PWR on the seed respiration rate of P+ during the first 24 h was suggested. Suppressed seed respiration by the pericarp is probably a cause of inhibited buckwheat germination under ESM conditions.

title: Genetic variation in heading dates and phenological parameters of Myanmar rice

description: Genetic variation in heading dates is essential for developing a rational rice cultivation program, optimizing irrigation practices, and advancing plant breeding in year-round irrigated environments. In this study, we investigated the heading dates of eight rice varieties with varying degrees of photoperiod sensitivity under natural field conditions by conducting year-round periodic sowing in 2019 in Nay Pyi Taw, located in the central region of Myanmar. We elucidated genetic differences in critical day length by observing the longest day length at 30 days before heading, which is likely to be the starting point for floral induction. We analyzed two phenological models: the conventional developmental rate (DVR) model and a modified model considering the critical day length. These analyses aimed to uncover the genetic differences in phenological parameters: temperature sensitivity, photoperiod sensitivity, and earliness among rice varieties. Incorporating the critical day length into the DVR model significantly improved its accuracy in predicting heading dates, particularly for photoperiod-sensitive rice varieties. The parameters derived from the 2019 data proved effective for predicting heading dates in 2018, especially for photoperiod-sensitive varieties. The genetic variation in critical day length and model parameters could be valuable for adapting rice cultivars to different seasons and determining yield and agronomic practices for varietal development programs. These findings contribute to a deeper understanding of rice phenology and the genetic basis for photoperiod sensitivity in Myanmar rice.

title: Effect of nitrogen fixation enhancing type <i>SEN1</i> gene on soybean growth

description: It is well known that the growth of legumes is greatly affected not only by fertilizer nitrogen but also by fixed nitrogen by symbiosis with rhizobia. We have reported that a polymorphism in <i>SEN1</i>, which is essential for nitrogen fixation in <i>Lotus japonicus</i>, could be used to enhance nitrogen fixation and plant growth. In this study, we examined whether the same strategy could be applied to <i>Glycine max</i>. Sequencing of orthologs of the <i>LjSEN1</i> gene in 38 soybean cultivars revealed that the polymorphism occurred at <i>Glyma.08g076300</i>. We defined the standard sequence that most of the cultivars retained as Peking type <i>SEN1</i>, and the mutated sequence found in Enrei as Enrei type <i>SEN1</i>. To investigate the effect of genotype differences, we generated near-isogenic lines by crossing Enrei with Fukuyutaka, which has Peking type <i>SEN1</i>, and analyzed their characteristics. The results showed that Enrei type enhanced nitrogen fixation activity and promoted plant growth. Since soybean SEN1 has been reported to be a homolog of vacuolar iron transporter-like protein, we investigated the iron content in the nodules. In the result, the iron content in the nodules of Enrei type was significantly higher than that of Peking type. Iron is known to be present in the active center of nitrogenase, and the high iron content may have contributed to the increased nitrogen fixation activity. These results suggest that Enrei type <i>SEN1</i> is a nitrogen fixation enhancing gene and that introduction of Enrei type <i>SEN1</i> may reduce nitrogen fertilizer application and increase yield.

title: Physiological and candidate gene analysis of <i>RG5</i>, a locus associated with a higher ratio of filled grains in rice (<i>Oryza sativa</i> L.)

description: In this report, we investigated physiological and genetic aspect of <i>RG5</i>, a locus increasing the ratio of filled grain in rice (<i>Oryza sativa L)</i>. <i>RG5</i> increased the accumulation of non-structural carbohydrates (NSCs) in the body, and NSCs might contribute to the development of grains after heading. With a chromosome segment substitution line containing ‘Kasalath’ <i>RG5</i> in the genetic background of the <i>japonica</i> cultivar ‘Koshihikari’, <i>RG5</i> might enlarge lower leaves and improve NSC supply to the sheath. Through the fine mapping using data plural mutans, we identified <i>NBS-LRR protein</i> (Os05g0380300) as a casual gene for expanding of lower leaves area by <i>RG5</i>. The single nucleotide polymorphism (SNP) of Kasalath caused a premature stop codon and lost function might increase the ratio of filled grains.
