TL;DR: A short resumé of each fungus in the Top 10 list and its importance is presented, with the intent of initiating discussion and debate amongst the plant mycology community, as well as laying down a bench-mark.

Journal ArticleDOI
Detection of Virulence to Wheat Stem Rust Resistance Gene Sr31 in Puccinia graminis. f. sp. tritici in Uganda.
TL;DR: Pathogenicity of Pgt-Ug99 was studied in seedling tests of available wheats containing Sr31, as well as other stem rust differential lines, and Virulence to the T. ventricosum-derived gene Sr38, which is linked to Lr37 and Yr17 and occurs in cultivars from Australia, the United Kingdom, and the United States, was not known previously.
Journal ArticleDOI
Detection of virulence to resistance gene Sr24 within race TTKS of Puccinia graminis f. sp. tritici.
TL;DR: The North American stem rust nomenclature system is proposed to be revised by the addition of four genes (Sr24, Sr31, Sr38, and SrMcN) as the fifth set and differentiates isolates within race TTKS into two separate races: TTKSK and TTKST, with avirulence and virulence on Sr24, respectively.
Journal ArticleDOI

TL;DR: The results from this study were inconclusive for determining the effectiveness of resistance genes Sr9e, 14, 21, and 29 against race TTKS.
