Trichoderma elicitor CP3 induces phosphorylation and nuclear export of SRP to enhance tomato resistance to gray mold
ABSTRACT Beneficial Trichoderma fungi enhance plant immunity, but the molecular mechanisms of elicitor-mediated immune priming are still not well defined. Here, we identified a cerato-platanin (CP) family elicitor, CP3, from T. asperellum that enhances tomato resistance to Botrytis cinerea. CP3 is secreted and localizes to the host nucleus, where it interacts with the tomato protein SRP.
