In cereals, several mildew resistance genes occur as large allelic series; for example, in wheat (Triticum aestivum and Triticum turgidum), 17 functional Pm3 alleles confer agronomically important race-specific to powdery (Blumeria graminis). The molecular basis of race specificity has been characterized wheat, but little is known about the corresponding avirulence mildew. Here, we dissected genetics six found that three major Avr loci affect avirulence, with a common locus_1 involved all...
The wheat Pm3 resistance gene against the powdery mildew pathogen occurs as an allelic series encoding functionally different immune receptors which induce upon recognition of isolate-specific avirulence (AVR) effectors from pathogen. Here, we describe identification five effector proteins pathogens wheat, rye, and wild grass Dactylis glomerata, specifically recognized by PM3B, PM3C PM3D receptors. Together with earlier identified AVRPM3A2/F2, AVRs PM3B/C, (AVRPM3B2/C2), (AVRPM3D3) belong to...
Cross-kingdom RNA interference (RNAi) is a biological process allowing plants to transfer small regulatory RNAs invading pathogens trigger the silencing of target virulence genes. Transient assays in cereal powdery mildews suggest that one or two effectors could lead near loss virulence, but evidence from stable RNAi lines lacking. We established transient host-induced gene (HIGS) wheat, and demonstrate targeting an essential housekeeping wheat mildew pathogen (Blumeria graminis f. sp....
