摘　　要：AP2/ERF(APETALA2/ethylene responsive factor)是植物特有的转录因子家族,广泛参与生长发育和胁迫应答等多种生物学进程。水稻是我国重要的粮食作物,但在其生长过程中受到多种逆境的影响。目前研究发现AP2/ERF转录因子在水稻逆境应答中扮演十分重要的角色。本文结合国内外研究进展,综述了水稻AP2/ERF转录因子的分类和结构,并梳理了不同亚家族的AP2/ERF转录因子响应病害、干旱、高盐和低温胁迫的功能和机制研究进展,为深入阐释水稻AP2/ERF转录因子调控逆境应答的分子网络及品种改良提供参考。AP2/ERF(APETALA2/ethylene responsive factor)is a family of plant specific transcription factors that are widely involved in various biological processes including plant growth and development and stress responses.Rice is an important food crop in China,but it is severely affected by multiple adverse environmental factors during growth period.It has been found that AP2/ERF transcription factors play important roles in stress response in rice.In this paper,we reviewed the classification and structure architecture of rice AP2/ERF transcription factors and summarized the function and molecular mechanism of different AP2/ERF subfamilies in rice response to disease,drought,saline,and low temperature stresses.This study provides a reference for further interpretation of the molecular network of rice AP2/ERFs-mediated regulatory network in stress responses and their application potential for stress resistance improvement of rice cultivars.
