The  WRKY  family are transcription factors, involved in plant development, and response to biotic and abiotic stresses. Moso bamboo is an important bamboo that has high ecological, economic and cultural value and is widely distributed in the south of China. In this study, we performed a genome-wide identification of  WRKY  members in moso bamboo and identified 89 members. By comparative analysis in six grass genomes, we found the  WRKY  gene family may have experienced or be experiencing purifying selection. Based on relative expression levels among  WRKY  IIc members under three abiotic stresses,  PeWRKY83  functioned as a transcription factor and was selected for detailed analysis. The transgenic Arabidopsis of  PeWRKY83  showed superior physiological properties compared with the WT under salt stress. Overexpression plants were less sensitive to ABA at both germination and postgermination stages and accumulated more endogenous ABA under salt stress conditions. Further studies demonstrated that overexpression of  PeWRKY83  could regulate the expression of some ABA biosynthesis genes ( AtAAO3 ,  AtNCED2 ,  AtNCED3 ), signaling genes ( AtABI1 ,  AtPP2CA ) and responsive genes ( AtRD29A ,  AtRD29B ,  AtABF1 ) under salt stress. Together, these results suggested that  PeWRKY83  functions as a novel  WRKY -related TF which plays a positive role in salt tolerance by regulating stress-induced ABA synthesis.
