Summary: Thirteen known Yr gene-associated markers were used to identify the resistance genes in selected wheat germplasm against stripe rust. High resistance was observed in 38 genotypes, while seven genotypes showed resistant to moderately resistant response. In race-specific phenotyping, 29.2% genotypes were immune, 58.3% were resistant, and 6.3% were moderately resistant. Yr5, Yr10, Yr15, and Yr24/26 were detected in different genotypes using specific markers. The frequencies of Yr5, Yr15, and Yr24/26 were higher compared to Yr10 in the tested wheat germplasm.

Summary: This study developed 166 new primary 1RS.1BL translocation lines by crossing rye varieties with several wheat cultivars. Cytogenetic and molecular analyses confirmed that all of these lines contained a pair of intact 1RS.1BL translocation chromosomes. The effects of the 1RS.1BL translocations from different rye cultivars on resistance to stripe rust varied, and the greatest genetic diversity was observed in translocations derived from diverse rye varieties but in the same wheat background. These diverse translocation lines provide ample opportunities for improving stripe rust resistance in wheat.

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: Wheat-Thinopyrum intermedium translocation lines were created to transfer the stripe rust resistance gene (YrT14) from the wheat-Th. intermedium addition line TAI-14 to common wheat. Among the obtained translocation lines, Zhongke 78 and Zhongke 15 showed excellent agronomic traits and high resistance to stripe rust. By screening and constructing a physical map, 14 markers specific for the alien chromosome were identified. These translocation lines can be used as a novel source of stripe rust resistance for wheat breeding.

Summary: A large genomic region on chromosome 6A in wheat has been identified to harbor multiple loci associated with favorable traits, including stripe rust resistance. Selective sweep analyses revealed specific genomic regions with strong artificial selection signals, containing traits related to resilience to environmental stress, various yield components, and quality characteristics. The discovery of the Hap1 haplotype associated with stripe rust resistance provides a concrete foundation for wheat improvement through genomic selection.

Summary: This study investigated the longterm population dynamics of P. striiformis f. sp. tritici in the United States using genotyping 1,083 isolates collected from 1968 to 2009. The results showed significant differences between populations prior to 2000 and those from 2000 to 2009, with the latter showing higher genotypic diversity and heterozygosity. The findings suggest the coexistence of newly introduced populations alongside established populations in the United States, providing valuable information for disease management strategies.

Summary: This study elucidated the molecular mechanism of high-temperature seedling-plant resistance in wheat to Puccinia striiformis f. sp. tritici. Overexpression of PSTG_11208 enhanced resistance, while the interaction between PstCEP1 and PSTG_11208 inhibited the resistance enhancement. Furthermore, TaTLP1 recognized pathogen invasion through interaction with PSTG_11208 and initiated downstream defense response. Silencing of TaFd1 affected photosynthesis stability and reduced resistance.
