摘要:

ERF转录因子(Ethylene Responsive Factor)属于植物AP2/ERF转录因子超家族,是植物应对生物与非生物胁迫的关键调控因子,其通过AP2/ERF保守结构域与顺式作用元件GCC-box结合,调控靶基因的时空表达。本文综述了植物ERF转录因子的结构特点、分类体系、分布规律及生物学功能:结构上包含DNA结合域、转录调控域等功能区域,其中AP2/ERF结构域第14和19位氨基酸是分类的关键标志;分类上,ERF与DREB亚族各自可进一步划分为6个亚组;分布上,不同植物中该家族成员数量差异显著,且双子叶植物ERF亚族成员通常多于单子叶植物。重点阐述了ERF在生物胁迫响应中的功能机制:一方面通过激活PRPDF1.2等抗病基因增强植物对病原菌的抗性,另一方面含EAR基序的ERF可作为负调控因子抑制靶基因表达。同时,本文总结了花生ERF的研究现状,包括家族鉴定(本课题组2022年在栽培花生中鉴定完成76个ERF家族成员)、抗逆功能验证(如AhERF008AhERF019可增强非生物胁迫耐受性)及当前存在的局限(如系统性分析不足、调控机制尚不明确等)。最后展望了未来研究方向,提出需结合多组学与基因编辑技术解析ERF介导的抗逆网络,为花生抗逆分子育种提供理论依据与技术靶点,助力花生抗逆工程研究。

Abstract:

Ethylene Responsive Factor (ERF) transcription factors belong to the plant AP2/ERF transcription factor superfamily and are key regulatory factors in plants responses to biotic and abiotic stresses. They bind to the cis-acting element GCC-box through the conserved AP2/ERF domain, thereby regulating the spatiotemporal expression of target genes. This article reviews the structural characteristics, classification system, distribution patterns, and biological functions of plant ERF transcription factors. Structurally, they contain functional regions such as the DNA-binding domain and transcriptional regulatory domain, among which the amino acids at positions 14 and 19 of the AP2/ERF domain are key markers for classification. In terms of classification, both the ERF and DREB subfamilies can be further divided into 6 subgroups. In terms of distribution, the number of members of this family varies significantly among different plants, and the number of ERF subfamily members in dicotyledonous plants is usually more than that in monocotyledonous plants. The functional mechanism of ERF in biotic stress response is emphatically elaborated as follows. On the one hand, it enhances plant resistance to pathogens by activating disease-resistant genes such as PR and PDF1.2; on the other hand, ERFs containing the EAR motif can act as negative regulators to inhibit the expression of target genes. At the same time, this article summarizes the research status of peanut ERF, including family identification (our research group identified 76 ERF family members in cultivated peanuts in 2022), verification of stress resistance functions (such as AhERF008 and AhERF019 can enhance abiotic stress tolerance), and current limitations (such as insufficient systematic analysis and unclear regulatory mechanisms). Finally, the future research directions are prospected, proposing that multi-omics and gene editing technologies should be combined to analyze the ERF-mediated stress resistance network, so as to provide a theoretical basis and technical targets for peanut stress resistance molecular breeding and facilitate research on peanut stress resistance engineering.
