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: A high-resolution linkage map was constructed using genotyping-by-sequencing strategy to identify 11 QTLs affecting kernel protein content in maize. Among these QTLs, qPC7 and qPC2-2 were identified in at least two environments, and a potential candidate gene, Zm00001d002625, was speculated for qPC2-2 locus.

Summary: In this study, 104 RIL populations generated by selfing Capsicum annuum x Capsicum frutescens F6 population were analyzed for their bioactive properties, phenolic composition, tocopherol and capsaicinoid profile. The red pepper lines showed a wide range of phenolic, flavonoid, anthocyanin contents, as well as antiradical activity and antioxidant capacity values. Capsaicin and dihydrocapsaicin levels varied greatly among the pepper samples. The major tocopherol was alpha tocopherol and the major phenolics were p-coumaric acid, ferulic acid, myricetin, luteolin, and quercetin. Principal component analysis successfully revealed similar genotypes.

Summary: This study found that higher phosphorus application led to increased shoot biomass and grain yield of cowpea plants in the field experiment, but did not significantly affect shoot or grain zinc content. There was no significant correlation between grain yield and zinc content under high soil phosphorus levels. The impact of higher phosphorus application on reducing plant zinc content may be genotype-dependent.

Summary: This study identified a QTL, qRgls1, related to gray leaf spot resistance in maize, but it was not detected in one of the RILs. However, this RIL exhibited similar resistance to the disease, possibly due to possessing a unique DNA segment. Results indicated that a specific gene, Zm00001d008467, could influence resistance to GLS.

Summary: In this study, the genetic basis of grain shape in a high-yielding hybrid rice variety was investigated using a set of recombinant inbred sister lines (RISLs) in four different environments. A total of 91 medium/minor-effect QTL were detected, with 3 new QTL identified. A QTL cluster was found to be consistent across all environments, and subsequent candidate gene analysis identified potential genes for further cloning, laying the foundation for high-yield breeding in rice.

Summary: The use of molecular breeding techniques has the potential to develop lentil genotypes biofortified with essential micronutrients such as iron and zinc, which can address the problem of global malnutrition. In this study, a genome-wide association study was conducted to identify genomic regions associated with seed iron and zinc content in lentil. Through genotyping-by-sequencing analysis, significant single nucleotide polymorphisms (SNPs) were identified, and association mapping revealed SNPs associated with seed iron and zinc content that were distributed across different chromosomes. Several candidate genes involved in iron and zinc metabolism were also identified. These findings provide valuable information for future breeding studies of lentil for nutrient biofortification.
