Summary: Grain chalkiness is a crucial factor influencing the market value of rice. This study identified 34 QTLs associated with grain chalkiness in 450 rice accessions through a genome-wide association analysis. Four candidate genes were identified as potential targets for molecular breeding to improve rice quality. These findings contribute to a better understanding of the genetic basis of grain chalkiness and provide gene resources for quality improvement in rice through molecular breeding.

Summary: Rice direct seeding is an important technology that can save labor and water, conserve environmental resources, and reduce greenhouse gas emissions. This study identified key genes associated with mesocotyl elongation in rice using a mapping population and detected multiple quantitative trait loci (QTLs) across different chromosomes. The investigation also identified a specific gene, LOC_Os03g50550, as a strong candidate for controlling mesocotyl elongation. These findings contribute to our understanding of the genetic mechanisms underlying rice's mesocotyl elongation and can help accelerate breeding programs for direct-seeded rice varieties.

Summary: This study identified a QTL for sheath blight resistance in rice and further fine-mapped it to a specific region. Functional analysis suggested that this QTL might enhance resistance to sheath blight through the activation of secondary metabolites biosynthesis and ROS scavenging system. Field trials demonstrated that this QTL conferred stable resistance and significantly reduced yield losses. These findings will contribute to the isolation of the QTL and its utilization in rice breeding programs against sheath blight.

Summary: This study identified QTLs and potential candidate genes associated with high soybean protein content. The identified genes may affect protein accumulation during seed development and sucrose and oil metabolism. These findings can aid in the development of soybean lines with increased protein content through marker-assisted selection.

Summary: Abundant natural variations and distinct phenotypic differentiation in grain weight and shape were observed in a large population of 2,453 accessions from the 3 K RGP. Through GWAS, 21 stable QTNs were consistently identified in at least two of 3-year trials, including six new QTNs. Candidate genes were further predicted for these new QTNs, providing valuable information for improving rice grain yield and quality through molecular breeding.

Summary: This study analyzed QTLs related to protein content in two introgression line populations of rice. A total of 25 QTLs were identified, with 19 of them co-locating with previously reported QTLs. Among them, QTL qGPC7.3 was validated as a gene related to total protein content in near-isogenic lines. This research lays the groundwork for further cloning of genes associated with nutritional quality in rice grains.

Summary: This study identified major quantitative trait loci (QTL) regions on linkage group 5 and another QTL on LG2 that are associated with Ascochyta lentis resistance in lentils. The QTL regions contain putative candidate genes potentially involved in defense responses to fungal infection, which could aid in marker-assisted resistance selection in lentil breeding programs.

Summary: This study conducted a large-scale field trial on the progeny of Salix suchowensis and analyzed the genetic factors underlying plant growth. The results showed that stem height and ground diameter were controlled by four quantitative trait loci, with two of them exerting a pleiotropic effect. The pleiotropic effect was found to result from the co-localization of genes with independent effects on stem height and ground diameter. Furthermore, the study revealed that height and circumference growth involve different tissue activities.

Summary: This research examined the distribution of cadmium in leaves and its binding characteristics in the cell wall of a low-Cd rice line, as well as the influence of silicon application on Cd accumulation in the cell walls of leaves. Results showed that silicon application significantly increased Cd concentration in leaves and cell wall fractions, potentially through regulating gene expression related to Cd adsorption and distribution.
