摘要
AP2/ERF(APETALA2/ethylene-responsive factor)是植物中最大的转录因子家族之一,至少含有1个由60~70个高度保守的氨基酸组成的特有的AP2结构域,根据AP2结构域数量和相似性可划分为5个亚家族:AP2(APETALA2)、DREB(Dehydration-responsive element binding proteins)、ERF(Ethylene-responsive factor)、RAV(Related to AB13/VP)和Soloist。AP2/ERF转录因子通过AP2结构域中的YRG和RAYD保守元件与靶基因结合,实现对相关基因的转录调控功能。目前,AP2/ERF已成为研究植物抗逆机制和活性成分生物合成的热点候选基因,越来越多植物AP2/ERF家族及其成员被报道。本研究对近年来有关AP2/ERF家族的最新研究成果进行了总结,综述了AP2/ERF家族转录因子的结构特征与分类,重点介绍了该类转录因子调控植物次生代谢产物的合成以及参与生物、非生物胁迫应答等方面的研究进展,并展望了AP2/ERF转录因子可能的研究热点和领域,以期为今后进一步挖掘和利用该类转录因子基因进行植物遗传改良以及种质创新提供参考。
AP2/ERF(APETALA2/ethylene responsive factor)is one of the largest transcription factor(TF)families in plants,which contains at least one specific AP2 domains composed of 60-70 highly conserved amino acids.Depending on the number and sequence similarity of AP2 domains,this family can be classified into five subfamilies:AP2(APETALA2),DREB(dehydration-responsive element binding proteins),ERF(ethyleneresponsive factor),RAV(related to AB13/VP),and Soloist.AP2/ERF TFs regulate their expression by binding to target genes through YRG and RAYD conserved elements in the AP2 domain.At present,AP2/ERF TFs have become a hot candidate gene for studying plant stress resistance mechanisms and biosynthesis of active ingredients.More and more AP2/ERF families and their members have been reported.In this review,we summarized the latest research achievements on plant AP2/ERF family,including the structural characteristics and classification,and the research progress of AP2/ERF TFs involved in regulation of plant secondary metabolites synthesis,participation in biological and abiotic stress response was mainly introduced.Meanwhile,possible hot research topics and fields of AP2/ERF were proposed,which may provide a reference for further mining and utilization of such transcription factor genes for plant genetic improvement and germplasm innovation.
