Summary: Stripe rust is a destructive disease that significantly reduces wheat yields globally. To control this disease, we developed a resistant cultivar called 'N2496', which showed high resistance and could be used in breeding programs. Through crossing 'N2496' with common wheat cultivars, we identified a quantitative trait locus (QTL) for stripe rust resistance on chromosome arm 6BL. The QTL explained a high percentage of phenotypic variation and was validated in other populations.

Summary: In this study, we conducted fine mapping and candidate gene analysis of the stripe rust resistance gene YrZM175 in the Chinese wheat cultivar Zhongmai 175. Through bulked segregant RNA-seq analysis, we identified a genomic interval on chromosome arm 2AL where YrZM175 is located and predicted a potential candidate gene for map-based cloning. Collinearity analysis and gene expression level analysis further supported the identification of the candidate gene. The fine mapping of YrZM175 provides a solid foundation for functional gene analysis and marker-assisted selection for improved stripe rust resistance in wheat.

Summary: Root architecture determines the efficiency of nutrient and water absorption in plants. We crossed two wheat cultivars with contrasting root morphologies to generate a recombinant inbred lines population. The plants were grown under controlled conditions and assessed for root and shoot traits. By comparing gene lists, we identified genes associated with root morphology in wheat and determined their physical locations on the Chinese Spring reference genome.

Summary: Rust diseases pose a significant threat to worldwide wheat production, primarily due to the emergence and spread of highly destructive strains of Puccinia. The use of genetically resistant cultivars is the common approach to minimize yield losses. Recent research has revealed that resistance genes can provide either all-stage or adult-plant resistance, with varying degrees of specificity. Advanced techniques like genotyping and gene isolation strategies have accelerated the transfer of resistance genes, but the combination of multiple genes is crucial for better and long-lasting resistance.

Summary: This paper reviews recently published studies on QTL mapping in peanut, focusing on the mapping populations used and traits related to kernel quality. It was found that several populations, including interspecific populations developed from crosses between synthetic tetraploids and elite varieties, have been used for QTL mapping, which has helped broaden the genetic base of cultivated peanut and identify beneficial wild alleles for economically important traits. Moreover, only a few studies have reported QTL related to kernel quality, mainly oil and protein content and fatty acid compositions. Among the 1261 QTL reported in this review, 413 (approximately 33%) were related to kernel quality, highlighting the importance of quality in peanut genetics and breeding. Exploiting QTL information could accelerate the development of highly nutritious superior cultivars in the face of climate change.

Summary: Soil salinity stress leads to significant yield losses in plants. To sustain yields in saline soils, it is important to identify crop varieties tolerant to salinity through genotyping and phenotyping. This study used digital phenotyping to investigate the growth response of a diverse collection of wheat accessions to salinity stress. The results showed that digital plant traits can be used to select salinity-tolerant accessions. A genome-wide association study identified novel genes and QTL for salinity tolerance. This study provides insights into the genetic basis of salinity tolerance and identifies potential candidate genes for future crop breeding.

Summary: This study identified the stripe rust resistance gene YR63 from a Portuguese hexaploid wheat landrace, which shows resistance to a wide spectrum of Pst races. The closely linked SNP marker associated with YR63 will facilitate its introgression into elite wheat cultivars through marker-assisted selection. The study highlights the importance of using long-read sequencing techniques for accurate detection of resistance genes within large gene clusters.
