摘　　要：APETALA2/乙烯响应因子(APETALA2/ethylene-responsive factor,AP2/ERF)转录因子家族是植物中最大的转录因子家族之一,其亚家族成员通过与下游互作基因启动子区域的GCC box、DRE/CRT等顺式作用元件特异性结合,激活或抑制相关基因的表达,参与果蔬的生长发育、成熟衰老、胁迫应答等生物学过程的调控。近年来越来越多的研究表明,AP2/ERF还可通过调控靶基因诱导乙烯、茉莉酸、水杨酸等多种植物激素反应或作为反应因子响应植物激素信号,参与植物激素介导的果蔬品质形成、生物胁迫及非生物胁迫应答相关的代谢通路,调节果蔬的品质及抗性。本文对AP2/ERF转录因子的结构特征及其在果蔬中的分类和分布进行了概述,并综述了果蔬逆境胁迫应答中AP2/ERF与主要激素信号相互作用以调控果蔬抗逆性的最新研究进展,以期从AP2/ERF转录因子激素调控的角度,为增强果蔬对逆境胁迫的抗性提供理论依据。The APETALA2/ethylene-responsive factor(AP2/ERF)transcription factor family is one of the largest transcription factor families in plants.Its subfamily members activate or repress the expression of related genes by specifically binding to cis-acting elements such as the GCC box and DRE/CRT in the promoter regions of downstream interacting genes,and participate in the regulation of biological processes such as growth and development,maturation and senescence,and stress response in fruits and vegetables.In recent years,an increasing number of studies have shown that AP2/ERF can also regulate the quality and resistance of fruits and vegetables by regulating target genes and inducing various phytohormone responses such as ethylene,jasmonic acid and salicylic acid,or by acting as a response factor in response to phytohormone signals.This article provides an overview of the structural characteristics of AP2/ERF transcription factors and their classification and distribution in fruits and vegetables and reviews the latest research progress in the regulatory effect of AP2/ERF on stress resistance in fruits and vegetables through interaction with the major hormone signals.It is our hope that this review will provide a theoretical basis for enhancing stress resistance in fruits and vegetables from the perspective of hormonal regulation of AP2/ERF transcription factors.
