植物WRKY转录因子家族基因抗病相关功能的研究进展

Advances in Research on Function of WRKY Transcription Factor Genes in Plant Resistance

植物基因组中,数目众多的转录因子参与植物的生长发育、物质代谢、响应生物和/或非生物胁迫等多种生物进程。WRKY基因家族是植物重要的转录因子家族,在抗病信号转导途径中起重要调控作用,因而成为分子植物病理研究领域中的热点。本文综述了WRKY转录因子基因在植物抗病反应中的作用和调节机制的最新研究进展,以期为深入研究WRKY基因家族在植物抗病反应中的作用,阐明植物抗病信号转导途径提供帮助。

Numerous transcription factors play important roles in the regulation of plant development,substance metabolism,and diverse biotic and abiotic stresses.Among them,WRKY family plays a vital role in signaling transduction of disease resistance.In this study,we have surveyed the genes in WRKY transcription factor family induced by plant disease pathogens and their regulation mechanisms involved in the resistance responses.These results will supply some suggestions for the further research about the molecular regulation of WRKY transcription factors in the plants resistance.
