Abstract

Plant defense responses to pathogens are induced after direct or indirect perception of effector proteins or their activity on host proteins. In fungal-plant interactions, relatively little is known about whether, in addition to avirulence effectors and immune receptors, other proteins contribute to specific recognition. The nucleotide-binding leucine-rich repeat (NLR) immune receptor Pm2a in wheat recognizes the fungal powdery mildew effector AvrPm2. We found that the predicted wheat zinc finger TaZF interacts with both the fungal av
