摘要:

ERF家族是植物所特有的APETALA2 / 乙烯响应因子(APETALA2 / ethylene-responsive factor,AP2 / ERF)转录因子家族的一个主要亚家族,其成员结构特点是仅含有 1个58-60 个氨基酸组成的AP2 / ERF结构域。有关该家族成员的大多数研究集中在与寒、旱等非生物胁迫方面,最近越来越多的研究表明ERF在植物抵御病虫侵害等生物胁迫方面也发挥着重要作用。ERF亚家族成员通过结合下游互作基因启动子区域的GCC box元件,从而激活或抑制这些病程相关基因的表达。同时ERFs参与水杨酸(salicylic acid,SA)、茉莉酸(jasmonic acid,JA)、乙烯(ethylene,ET)及过氧化氢(H2O2)等多种激素的信号途径,通过相互促进/拮抗高效协调体内不同激素抵御病原菌的入侵,提高植物的抗病、抗虫性。本文综述了ERF 转录因子的结构功能特点、在不同植物抗生物胁迫中的调控方式,以及其通过协调不同激素信号途径相互作用来提高植物抗病虫的最新研究进展,并对其应用前景进行了展望。

Abstract:

ERF family is a major subfamily of plant-specific APETALA2/ethylene-responsive factor(AP2/ERF)transcription factor family. Its member structure is characterized by containing only one AP2/ERF domain composed of 58-60 amino acids. Most researches on the members of this family were focused on abiotic stresses such as cold and drought,and recent studies demonstrate that ERFs play an important role in resisting plant diseases and insect pests. These ERF subfamily members can bind to the GCC box element within the promoter region of their interactive genes,and activate or inhibit the expressions of these pathogenesis-related genes. Moreover,more researches confirmed that ERFs participate in salicylic acid(SA),jasmonic acid(JA),ethylene(ET),H2O2,and other hormone signaling pathways,and effectively coordinate different hormones to resist the invasion of pathogenic bacteria,and to improve plants’ resistance to disease and insect through mutual promotion/antagonism. This paper reviews the structure features of ERF transcription factors(TF),their regulatory mechanisms in different plants’ antibiotic stresses,and the latest progresses in improving plant resistance to diseases and insect pests by coordinating the interaction of different hormone signaling pathways. Finally,the paper prospects the application of ERF in plant disease resistance breeding.
