  • Wheat stem rust resistance gene Sr6-mediated resistance is enhanced at lower temperatures whereas Sr13 and Sr21 resistances are enhanced at higher temperatures. Here, the authors clone Sr6 and show the divergent molecular pathways governing temperature-dependent resistance among these genes.

  • Strain Ug99 of the wheat stem rust pathogen, Puccinia graminis f. sp. tritici, is a major threat to global food security. Here, the authors present genomic analyses supporting that Ug99 arose as a result of non-sexual genetic exchange between dikaryotic ancestors.

  • The authors developed a platform for rapid identification of interacting plant immune receptors and pathogen avirulence proteins by library screening in protoplasts, then used it to identify new wheat stem rust Avr genes recognized by known wheat resistance genes.

  • The tall wheat grass-derived stem rust resistance genes Sr26 and Sr61 are among a few ones that are effective to all current dominant races of stem rust, including Ug99. Here, the authors show that the two genes are present in a small non-recombinogenic segment but encode two unrelated NLR proteins.

  • Stem rust is an important disease of wheat and resistance present in some cultivars can be suppressed by the SuSr-D1 locus. Here the authors show that SuSr-D1 encodes a subunit of the Mediator Complex and that nonsense mutations are sufficient to abolish suppression and confer stem rust resistance.
