PM2b, a CC-NBS-LRR protein, interacts with TaWRKY76-D to regulate powdery mildew resistance in common wheat.

ABSTRACT: Powdery mildew caused by Blumeria graminis f. sp. tritici (Bgt) is a destructive disease of wheat throughout the world. Host resistance is considered the most sustainable way to control this disease. Powdery mildew resistance gene Pm2b was mapped to the same genetic interval with Pm2a and PmCH1357 cloned previously, but showed different resistance spectra from them, indicating that they might be caused by different resistance genes or alleles. In this study, Pm2b was delimited to a 1.64 Mb physical interval using a large segregating population containing 4,354 F_2:3 families of resistant parent KM2939 and susceptible cultivar Shimai 15. In this interval, TraesCS5D03G0111700 encoding the coiled-coil nucleotide-binding site le
