摘要
AP2/EREBP(APETALA2/ethylene-responsive element binding proteins)是一个起源古老的转录因子超家族,它含有1个或2个由约60-70个氨基酸残基组成的非常保守的DNA结合域(DNA-bindingdomain),即AP2/ERF结构域。根据AP2/ERF结构域的数目,AP2/EREBP转录因子可以分为2个亚族:EREBP亚族(具有1个AP2/ERF结构域)和AP2亚族(具有2个AP2/ERF结构域)。AP2亚族转录因子有调控花、胚珠和种子发育的功能,而EREBP亚族转录因子(包括DREB类和ERF类)的主要功能是调节植物对激素(乙烯和ABA等)、病原和胁迫(低温、干旱及高盐)等的应答反应。本文讨论了AP2/EREBP转录因子在植物发育和胁迫应答中的研究进展。
APETALA2/ethylene responsive-element binding proteins （AP2/EREBPs） are an ancient superfamily of transcription factors. AP2/EREBPs are distinguished by containing one or two conserved DNA binding domains, the so-called AP2/ERF DNA binding domain, which consists of approximately 60-70 amino acid residues. According to the number of AP2/ERF domains, the AP2/EREBP family is divided into two subfamilies： EREBPs, which contain one AP2/ERF domain, and AP2s, which contain two AP2/ ERF domains. The main function of the AP2 subfamily is regulation of development of flowers, ovules, and seeds etc., and the EREBP subfamily plays important roles in regulating the response to plant hormones （ethylene, ABA etc.）, pathogen attack and stresses （cold, drought and high salt etc.）. This paper reviews the progress of research into the AP2/EREBP family of transcription factors in the development and stress response of plants.
