Puccinia graminis f. sp. tritici (Pgt) causes wheat stem rust, a devastating fungal disease. The Sr35 resistance gene confers immunity against this pathogen's most virulent races, including Ug99. We used comparative whole-genome sequencing of chemically mutagenized and natural Pgt isolates to identify named AvrSr35 that is required for avirulence. encodes secreted protein capable interacting with triggering the immune response. show origin on associated nonfunctionalization by insertion...
Genome-wide single nucleotide polymorphism (SNP) variation allows for the capture of haplotype structure in populations and prediction unobserved genotypes based on inferred regions identity-by-descent (IBD). Here we have used a first-generation wheat map created by targeted re-sequencing low-copy genomic reference panel 62 lines to impute marker diverse winter cultivars from U.S. Great Plains. The IBD segments between population were identified SNP genotyped using 90K iSelect array...
