Summary: This study used a population of recombined inbred lines of Brassica napus to investigate the genetics of seed germination, uncovering a novel major QTL regulating germination. Transcriptome analysis revealed differences in metabolic pathways such as sugar, protein, lipid, and amino acid metabolism between the high germination rate variety 'Holly' and other varieties.

Summary: This study identified 10 QTLs for drought tolerance in soybean using a recombinant inbred line population developed from a cross between a drought-tolerant and a susceptible cultivar. The QTLs were found on seven chromosomes, with some overlapping or located close to previously reported related QTLs and/or potential candidate genes. These QTLs and closely linked markers could be used in marker-assisted selection to accelerate breeding for drought tolerance in soybean.

Summary: This study identified a stem bending 1 (stb1) mutant in rapeseed with abnormal stem development and conducted phenotype characterization, genetic analysis, quantitative trait locus mapping, and transcriptome analysis to elucidate the molecular mechanisms involved. The down-regulated genes in the mutant were mainly related to auxin transport and coenzyme metabolism processes, suggesting defects in polar auxin transport as a potential cause for the phenotype of the stb1 mutant. These findings lay a foundation for further investigation into the molecular mechanisms of stem development in rapeseed.

Summary: This study investigated the changes in chlorophyll content in wheat flag leaves under different phosphorus conditions and identified 157 QTLs associated with this trait. Six major QTLs were detected under multiple phosphorus conditions, and two novel major QTLs were discovered. Additionally, SNP markers closely linked to these QTLs were validated.

Summary: This study aimed to identify quantitative trait loci (QTLs) associated with soybean isoflavone contents. A mutant-based F-2 population was created and a linkage map was constructed. Thirteen QTLs related to agronomic traits and 29 QTLs associated with isoflavone contents were identified. The major QTL associated with isoflavone contents was located on chromosome 11, and four beta-glucosidase genes were identified as potential candidates involved in high isoflavone contents.

Summary: The study detected quantitative trait loci (QTLs) for panicle apical abortion (PAA) in rice using chromosome segment substitution lines (CSSLs), identifying a novel major effector QTL, qPAA7. The research provides a foundation for further cloning and functional characterization of the target gene from this locus.

Summary: This study reveals the correlation between rhizobial nodulation outer proteins NopL and NopT and the nodule number and nodule dry weight in soybean. The quantitative trait loci associated with their interactions were identified using chromosome segment substitution lines. Additionally, 17 candidate genes were identified as potential interactors with NopL and NopT.

Summary: Phosphorus is essential for plant growth but limited in most arable lands. Enhancing P efficiency in soybean can increase grain and biomass production by promoting biological nitrogen fixation. Genetic approaches have revealed mechanisms for soybean adaptation to P deficiency, particularly focusing on root modifications.

Summary: This study identified candidate genes associated with nodulation traits and regulated by Sinorhizobium fredii HH103 in soybean. A total of 68 genes were found in three quantitative trait loci (QTLs) on chromosomes 02, 05, and 20. Additionally, a potential gene, Glyma.05G240500, was identified as a positive regulator of soybean nodulation in response to S. fredii HH103. The investigation of SNPs in the regulatory areas of Glyma.05G240500 haplotype revealed the relationship between haplotypes and soybean nodulation phenotypes.

Summary: In this study, high-resolution QTL mapping was conducted to identify the genetic regions responsible for rice grain quality traits. A total of 15 QTLs were identified, including one overlapping with previously reported QTLs and the others being novel. These findings will facilitate the fine mapping and pyramiding of these QTLs, leading to genetic improvement of rice grain quality.

Summary: This study identified novel genetic variants associated with susceptibility to endometriosis in a Taiwanese population through genome-wide association study and replication, while also observing eQTL related to the expression of the INTU gene. The findings suggest that these genetic variants may impact the risk of endometriosis in the Taiwanese population.

Summary: The study demonstrated significant impacts of salinity stress on survival traits of barley seedlings, particularly showing pronounced effects on shoot length and seedling vigour index length. QTL analysis revealed multiple genetic loci associated with salinity tolerance, some of which may potentially harbor candidate genes with functional significance.
