Stem rust,caused by Puccinia graminis ***(Pgt),threatens global wheat *** of cultivars with increased resistance to stem rust by identification,mapping,and deployment of resistance genes is the best strategy for controlling the *** this study,we performed fine mapping and characterization of the all-stage stem rust resistance(sr)gene sr8155b1 from the durum wheat line *** seedling tests of biparental populations,sr8155b1 was effective against six Chinese Pgt races *** a segregating population of 5060 gametes,sr8155b1 was mapped to a 0.06-cM region flanked by markers Pku2772 and Pku43365,corresponding to 1.5-and 2.7-Mb regions in the Svevo and Chinese Spring reference *** regions include several typical nucleotide-binding leucine-rich repeat(NLR)and protein kinase genes that represent candidate *** them,three NLR genes and three receptor-like protein kinases were highly polymorphic between the parental lines and their transcripts were upregulated in the homozygous resistant line TdR2 relative to its susceptible sister line *** markers(Pku2772,Pku43365,Pku2950,and Pku3721)developed in this study,together with seedling resistance responses,correctly predicted sr8155b1 absence or presence in 78 tetraploid wheat genotypes *** presence of sr8155b1 in tetraploid wheat accessions CItr 14916,PI 197492,and PI 197493 was confirmed by mapping in three F_(2)*** genetic map and linked markers developed in this study may accelerate the deployment of sr8155b1-mediated resistance in wheat breeding programs.
