Plants have evolved a complex and elaborate signaling network to respond appropriately to the pathogen invasion by regulating expression of defensive genes through certain transcription factors. The APETALA2/ethylene response factor (AP2/ERF) family members have been determined as key regulators in growth, development, and stress responses in plants. Moreover, a growing body of evidence has demonstrated the critical roles of AP2/ERFs in plant disease resistance. In this review, we describe recent advances for the function of AP2/ERFs in defense responses against microbial pathogens. We summarize that AP2/ERFs are involved in plant disease resistance by acting downstream of mitogen activated protein kinase (MAPK) cascades, and regulating expression of genes associated with hormonal signaling pathways, biosynthesis of secondary metabolites, and formation of physical barriers in an MAPK-dependent or -independent manner. The present review provides a multidimensional perspective on the functions of AP2/ERFs in plant disease resistance, which will facilitate the understanding and future investigation on the roles of AP2/ERFs in plant immunity.
植物已经进化出一个复杂而精细的信号网络，通过某些转录因子调节防御基因的表达，从而对病原体入侵做出适当反应。APETALA2/乙烯反应因子（AP2/ERF）家族成员已被确定为植物生长、发育和应激反应的关键调节因子。此外，越来越多的证据表明AP2/ERF在植物抗病性中起关键作用。在这篇综述中，我们描述了AP2/ERF在针对微生物病原体的防御反应中功能的最新进展。我们总结出，AP2/ERF通过在丝裂原活化蛋白激酶（MAPK）级联反应的下游起作用，并以MAPK依赖或独立的方式调节与激素信号通路、次生代谢物生物合成以及物理屏障形成相关的基因表达，从而参与植物抗病性。本综述提供了关于AP2/ERF在植物抗病性中功能的多维度视角，这将有助于理解和未来研究AP2/ERF在植物免疫中的作用。
