主　　题：effector JA signaling Phytophthora pathogen plant immunity 

摘      要：The oomycete pathogen Phytophthora sojae is a causal agent of soybean root *** colonization of soybeans,*** secretes various RXLR effectors to suppress host immune responses,supporting successful *** research has demonstrated that the RXLR effector Avh94 functions as a virulence effector,but the molecular mechanism underlying its role in virulence remains ***,we demonstrate that Avh94 overexpression in plants and pathogens promotes Phytophthora ***94 interacts with soybean JAZ1/2,which is a repressor of jasmonic acid(JA)***94 stabilizes JAZ1/2 to inhibit JA signaling and silencing of JAZ1/2 enhances soybean resistance against ***,*** lines overexpressing Avh94 inhibit JA ***,exogenous application of methyl jasmonate improves plant resistance to *** together,these findings suggest that *** employs an RXLR effector to hijack JA signaling and thereby promote infection.
