Abstract: WRKY DNA binding transcription factors play pivotal roles in the regulation of plant development, substance metabolism, resistance, and senescence. Based on the clear genome of rice, studies on WRKY gene function are dramatically enhanced nowadays. And several evidences implicate WRKY factors in transcriptional reprogramming during rice resistance response, senescence process, sugar metabolism, and plant architecture. In addition, previous nomenclature of rice WRKY proteins was confusing. Therefore it is necessary to collate the corresponding WRKY proteins and review the recent progress of WRKY protein research.

Key words: rice, WRKY gene, transcription factor, gene function
