Summary: Stripe rust, a worldwide wheat disease caused by Puccinia striiformis f. sp. tritici, results in devastating crop losses, but can be controlled through combining multiple resistance genes in new cultivars. A study identified two resistance QTLs on chromosomes 3B and 3D in winter wheat cultivars, showing their importance in future breeding efforts.

Summary: Two loci on chromosomes 2BS and 6AL were found to significantly contribute to stripe rust resistance in current European winter wheat germplasm. These findings provide valuable information for the breeding programs aimed at developing rust resistant cultivars. Genomic association analysis identified 12 SNP markers on six wheat chromosomes that consistently showed effects on adult plant stripe rust resistance. Two highly predictive markers on chromosomes 2BS and 6AL were validated in three independent populations, indicating their potential for efficient selection of resistant cultivars.

Summary: The adult-plant stripe rust resistance gene, Yr86, in Chinese wheat cultivar Zhongmai 895 was mapped to the physical interval 710.2-713.2 Mb on chromosome 2A. This gene provides stable resistance to stripe rust at the adult-plant stage and has the potential to be a new gene for this type of resistance. Multiple KASP markers associated with Yr86 were developed and can be used for marker-assisted selection and further studies on this resistance gene.

Summary: This study identified quantitative trait loci (QTL) associated with field resistance to stripe rust in hard winter wheat through evaluation of recombinant inbred lines (RILs, n = 204) in replicated field trials. Genetic linkage maps were developed using single nucleotide polymorphism (SNP) markers, and QTL analysis identified genomic regions on chromosome arms that were associated with stripe rust resistance. PCR-based SNP marker assays were developed to efficiently identify these genomic regions in breeding populations.

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.
