WRKY转录因子家族调控植物逆境胁迫响应

WRKY Transcription Factors in Regulation of Stress Response in Plant

WRKY转录因子是一组含有保守的WRKYGQK结构域的蛋白质家族,广泛参与植物的营养体生长、器官发育、物质代谢和对各种生物、非生物胁迫的响应过程。目前,对WRKY家族转录因子的研究主要集中在不同物种中WRKYs对逆境胁迫响应的信号转导机制的解释。以近年来发表的关于WRKYs的研究成果为基础,综述了WRKY家族成员的不同功能,讨论了WRKYs的不同成员在植物正常生长发育的重要作用。模式植物之外其他的植物物种中WRKY家族成员的作用报道相对较少,且缺少全面的研究和分析;WRKYs参与的很多信号通路还没有完全清晰,这些问题有待深入研究。

WRKY transcription factor families are characterized by a highly conserved WRKYGQK domain and involved in plant development,metabolism,answering to comprehensive biotic or abiotic stress. Recently,the research of WRKY transcription factors concentrate on stress response signaling network in different species. It reviewed progress of WRKYs members,and indicated that WRKY transcription factors play a heavy role in plant growth and regulating stress response. At the same time,there is less reported of WRKYs function in plant species besides model plant Arabidopsis thaliana and most of them focus on systematic research and analysis. In addition,numerous networks of WRKY transcription factors are still unclear.
