ENHANCED DISEASE RESISTANCE 1 (EDR1) is a negative regulator of powdery mildew resistance, cell death and ethylene-induced senescence. To identify components involved in EDR1 signaling, we performed a forward genetic screen for edr1 suppressors. In this screen, we identified the hpr1-4 mutation, which partially suppresses edr1-mediated resistance to the powdery mildew pathogen Golovinomyces cichoracearum and mildew-induced cell death. However, the hpr1-4 mutation enhanced the ethylene-induced… CONTINUE READING
