WRKY TFs have been reported to be involved in many aspects of plant development, including senescence, trichome development, biosynthesis of secondary metabolites, flowering, and seed development and germination. Substantial evidence has demonstrated that many WRKY genes also participate in various stress responses. We identified 171 WRKY genes, including JTY(57), LWM(59) and F106(55) , all genes were divided into 7 subfamilies.
