Chemical induction of leaf senescence and powdery mildew resistance involves ethylene-mediated chlorophyll degradation and ROS metabolism in cucumber
文献摘要：
Timely initiation of leaf senescence is an integral part of plant development and,importantly,an adaptive strategy by which plants cope with various stresses,e.g.to limit the spread of pathogens.Powdery mildew is a major cucumber disease that promotes the initiation/progression of leaf senescence and reduces leaf photosynthesis,resulting in severe losses of yield and quality.However,how powdery mildew induces leaf senescence and how cucumber plants respond to enhance their resistance remain unclear.Here,with established agrochemical induction and pathogen inoculation systems,we demonstrate that both probenazole(PBZ)and powdery mildew activate ethylene(ET)biosynthesis and signal transduction,consequently promoting leaf senescence and enhancing plant resistance to powdery mildew through CsEIN3 to directly upregulate the expression of CsCCGs and CsRBOHs.Our analysis convincingly suggests that the regulation of leaf senescence and powdery mildew resistance is interconnected and mediated mainly by ET in cucumber.
