Stripe (yellow) rust, caused by the biotrophic fungal pathogen Puccinia striiformis f. sp. tritici (Pst), is emerging as a serious threat to wheat (Triticum aestivum L.) production in many regions of North America. Genetic resistance stripe rust typically conditioned products genes that detect pathogen-associated molecular patterns and initiate cascade signalling events, culminating generation ...

Stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici Eriks.) is a serious disease of wheat (Triticum aestivum L.). Resistance genes Yr5 and Yr15 are the only known all-stage resistance genes that defeat all stripe rust races currently found in the United States. Previously mapped markers for these genes, however, show limited polymorphism across diverse genotypes and/or map at a ...

Analysis of DNA sequence variation among genotypes is useful for differentiation of wheat accessions, selection strategies and genetic development of crop plants. We screened molecular markers for yellow rust resistance genes (Yr7, Yr9, Yr15, Yr18, Yr26, and YrH52), which are in the gene-rich regions of wheat chromosomes 1B, 2B, and 7D, to investigate DNA sequence differences and repeat mo...

Yellow rust (YR) epidemics have affected wheat productivity worldwide. YR resistance (Yr) is eminent in wheat; however, it continuously invaded by evolving pathogen Puccinia striiformis (Pst.). Understanding the Yr genes’ diversity among available germplasm paramount to developing YR-resistant cultivars. In this study, 14 genotypes were screened for their relative index (RRI) and genes/QTL via ...

Stripe rust is a devastating disease in wheat that causes substantial yield loss around the world. The most effective strategy for mitigating to develop resistant cultivars. wild relatives of are good sources resistance fungal pathogens. Here, we used genome-wide association study (GWAS) identify loci associated with stripe (causal agent: Puccinia striiformis f. sp. tritici) emmer (Triticum dic...
