Research Experience/Achievement

 

During plant and microbe interaction, potential bacteria pathogens deploy type III effectors and toxins to disrupt plant immune responses. Coronatine, as a non-host toxin, have been found to suppress plant defense responses by hijack JA-dependent signaling pathway to promote bacterial virulence. We have found that COR is a multifunctional defense suppressor. We continue to study the virulence function of COR how to regulate plant secondary metabolites to promote bacteria growth and suppress plant defense response.
