Summary: In this study, a new race-specific seedling stripe rust resistance gene, YrK, was identified on wheat chromosome 5BL through genotyping-by-sequencing and bulked segregant RNA sequencing. Functional molecular markers for YrK were developed. Additionally, four adult plant resistance (APR) loci were mapped on wheat chromosome arms 1BL, 2AS, 2BS, and 4AL. The findings of this study provide valuable resources for the development of rust-resistant wheat varieties.

Summary: Stripe rust caused by Puccinia striiformis f.sp. tritici is a serious threat to wheat crops globally, including Kazakhstan. This study evaluated 70 winter wheat genotypes for resistance, identifying 42 entries with resistance reactions, six of which were considered to have a high level of adult plant resistance. Key resistance genes such as Yr10, Yr5, and Yr15 were identified in the wheat germplasm, providing potential targets for breeding programs.

Summary: This study investigated the application of genomic selection in major diseases of spring wheat and compared the impact of different models on prediction accuracies. The results showed that the M3 model, which incorporated GE interactions, outperformed the M2 model in reducing residual variance and improving prediction accuracies.

Summary: This study determined the genetic basis of resistance to leaf rust (LR) and stripe rust (YR) in wheat variety Borlaug 100. Multiple resistance genes were found to significantly affect the severity of the diseases, and their additive and interactive effects were observed. The results provide resistance sources for wheat breeding programs.

Summary: This study mapped QTLs associated with resistance to leaf spot, leaf rust, stripe rust, and common bunt in two wheat populations using the IWGSC physical map. A total of 82 QTLs were identified, with 29 of them associated with disease severity in all environments. This methodology provides a resource for comparing QTLs across different populations and studies based on improved physical information.

Summary: In this study, a large set of wheat germplasms was characterized to determine the presence of the broad-spectrum resistance Yr15 gene. The results showed that wild wheat cultivars are a good source of the Yr15 gene, and introgression of this gene into the cultivated wheat germplasm should be performed to manage the Pst pathogen in the future.

Summary: The deployment of combinations of resistance genes in future wheat cultivars can save yield losses caused by the stripe rust pathogen. This study identified a new resistance gene YrAW12 and several genomic regions controlling stripe rust resistance in a Tunisian landrace Aus26670. The detailed mapping of these genomic regions will lead to permanent designation of these loci.

Summary: This study demonstrated that the endophytic fungus Epicoccum nigrum HE20 isolated from a healthy wheat plant showed strong inhibitory potential against stripe rust in wheat. The application of E. nigrum HE20 led to a significant reduction in disease severity and an overexpression of defensive genes in the infected plants. These findings suggest that E. nigrum HE20 could be an effective bioagent for controlling stripe rust.

Summary: In this study, quantitative trait loci (QTL) for stripe rust resistance in winter wheat cultivar Pindong 34 were identified, including QTL for adult-plant resistance (APR) and all-stage resistance (ASR). These QTLs could be valuable for the development of wheat cultivars with durable resistance to stripe rust.

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: The wheat SQUAMOSA genes play a crucial role in regulating spikelet development and floral identity by repressing the expression of other MADS-box genes in the SVP Glade, ultimately impacting crop productivity. Manipulating SVP and SQUAMOSA genes can potentially enhance spike architectures and increase grain yields.

Summary: In this study, a potential candidate gene, TraesCS1D02G155200, was identified as a class III homeodomain-leucine zipper transcription factor that regulates morphological traits in wheat. Mutations in this gene were found to cause phenotypic alterations including leaf curling, spike abnormality, dwarfism, and delayed heading. The complementary sites for miRNA165/166 associated with this gene were highly conserved in a survey of 1397 wheat accessions.
