主　　题：GhWRKY33 Verticillium dahliae Jasmonate acid GhJAZ3 Defense response 

摘      要：Verticillium wilt,caused by Verticillium dahliae,seriously restricts the yield and quality improvement of *** studies have revealed the involvement of WRKY members in plant defense against ***,but the underlying mechanisms involved need to be further ***,we demonstrated that Gossypium hirsutum WRKY DNA-binding protein 33(GhWRKY33) functions as a negative regulator in plant defense against ***33 expression is induced rapidly by *** and methyl jasmonate,and overexpression of GhWRKY33 reduces plant tolerance to *** in *** RT-PCR analysis revealed that expression of several JA-associated genes was significantly repressed in GhWRKY33 overexpressing transgenic *** one-hybrid analysis revealed that GhWRKY33 may repress the transcription of both AtERF1 and GhERF2 through its binding to their ***-protein interaction analysis suggested that GhWRKY33 interacts with *** JASMONATE ZIM-domain protein 3(GhJAZ3).Similarly,overexpression of GhJAZ3 also decreases plant tolerance to ***,GhJAZ3 acts synergistically with GhWRKY33 to suppress both AtERF1 and GhERF2 *** results imply that GhWRKY33 may negatively regulate plant tolerance to *** via the JA-mediated signaling pathway.
