小麦ERF亚族转录因子参与逆境胁迫的研究进展

Advances in Research on Function of Wheat ERF Transcription Factor Subfamily in Stress Response

小麦是中国三大粮食作物之一,其生长发育过程中会受到多种逆境胁迫的影响。AP2/EREBP是植物特有的一个庞大的转录因子超家族,普遍参与生长发育和逆境胁迫应答等生物学进程。ERF类转录因子是AP2/EREBP转录因子超家族的一个亚族。本研究结合国内外相关研究进展,简要综述了小麦ERF亚族转录因子的结构特征与分布,重点阐述近年来小麦ERF亚族转录因子响应高盐、干旱、低温、重金属、病原菌侵染等逆境胁迫的功能和机制研究进展,最后展望了ERF亚族转录因子的研究方向和应用前景。

Wheat is one of the three major grain crops in China,but its growth and development might be affected by multiple adverse stresses.AP2/EREBP is a superfamily of plant specific transcription factors which are widely involved in biological processeses such as growth,development and stress response.The ERF transcription class is a subfamily of the AP2/EREBP superfamily.Here,the structural characteristics and distributions of ERF subfamily transcription factors in wheat were briefly introduced.And the recent research progresses of the functions and mechanisms of ERF subfamily transcription factors in wheat was emphasized in response to stresses such as high salt,drought,low temperature,heavy metal and pathogen infection.Finally,the research direction and application prospect of ERF subfamily transcription factors were prospected.
