Evidence of a distinct Blumeria graminis f. sp. tritici pathotype structure in Australian wheat powdery mildew: implications for resistance breeding. The obligate biotrophic fungus Blumeria graminis f. sp. tritici (Bgt) is the causal agent of wheat powdery mildew.

A conserved fungal transcription factor domain drives protein-protein interactions and necrotrophic effector-mediated virulence in Parastagonospora nodorum The fungal pathogen Parastagonospora nodorum utilises necrotrophic effectors (NEs) to cause chlorosis and necrosis on wheat. NE expression is mediated by an assortment of transcription factors (TF), t...
