Background  The WRKY proteins are a superfamily of transcription factors and members play essential roles in the modulation of diverse physiological processes, such as growth, development, senescence and response to biotic and abiotic stresses. However, the biological roles of the majority of the WRKY family members remains poorly understood in soybean relative to the research progress in model plants.    Results  In this study, we identified and characterized  GmWRKY40 , which is a group IIc  WRKY  gene. Transient expression analysis revealed that the GmWRKY40 protein is located in the nucleus of plant cells. Expression of  GmWRKY40  was strongly induced in soybean following infection with  Phytophthora sojae , or treatment with methyl jasmonate, ethylene, salicylic acid, and abscisic acid. Furthermore, soybean hairy roots silencing  GmWRKY40  enhanced susceptibility to  P. sojae  infection compared with empty vector transgenic roots. Moreover, suppression of  GmWRKY40  decreased the accumulation of reactive oxygen species (ROS) and modified the expression of several oxidation-related genes. Yeast two-hybrid experiment combined with RNA-seq analysis showed that GmWRKY40 interacted with 8 JAZ proteins with or without the WRKY domain or zinc-finger domain of GmWRKY40, suggesting there were different interaction patterns among these interacted proteins.    Conclusions  Collectively, these results suggests that  GmWRKY40  functions as a positive regulator in soybean plants response to  P. sojae  through modulating hydrogen peroxide accumulation and JA signaling pathway.

GmWRKY40, a member of the WRKY transcription factor genes identified from Glycine max L., enhanced the resistance to Phytophthora sojae
