摘　　要：作物抗逆性是多基因控制的复杂数量性状,各基因相互协调构成复杂的调控网络。其中,转录因子能特异性结合下游基因启动子区域的顺式作用元件进而调控其表达,在作物逆境应答中发挥重要作用。NAC(NAM,ATAF1/2和CUC2)转录因子是植物特有的、具有多种生物学功能的、最大的转录因子家族之一。该文旨在总结国内外相关研究进展,首先简要综述NAC转录因子的结构特征,然后重点阐述小麦NAC转录因子响应条锈病、白粉病、赤霉病等生物逆境和干旱、高盐等非生物逆境的功能和机制研究进展。研究者目前克隆并研究了较多参与小麦条锈病抗性、干旱胁迫应答的NAC转录因子家族成员基因,而参与白粉病、赤霉病等其他病害抗性和盐胁迫等其他非生物胁迫应答的家族成员基因的研究还相对较少。较多基因的功能鉴定仅通过拟南芥遗传转化得以初步验证,其参与逆境胁迫的分子调控机制研究也相对浅显。最后,展望小麦NAC转录因子的研究方向和应用前景。该文可为更便捷高效地开展小麦抗逆性遗传改良提供参考。Crop resistance is a complex quantitative trait controlled by many genes,which coordinate with each other to form a complex regulatory network.Transcription factors can regulate the expression of downstream gene by specifically binding to the cis-acting elements in the promoter region,playing important roles in crop resistance responding.The NAC(NAM,ATAF1/2,and CUC2)family is one of the largest families of plant-specific transcription factors with multiple biological functions.This paper aims to summarize relevant research progress at home and abroad.Firstly,the structural characteristics of NAC transcription factor were briefly introduced.Then the recent research progresses of the functions and mechanisms of NAC transcription factor in wheat in response to biotic stresses such as stripe rust,powdery mildew and fusarium head blight,as well as abiotic stresses such as drought and high salinity,were emphasized.Relatively more NAC transcription factor responding to stripe rust and drought were cloned and analyzed,while there were relatively less studies responding to powdery mildew,fusarium head blight as well as other diseases,and salt stress as well as other abiotic stresses.Besides,the functional identification of most of these genes has only been performed through genetic transformation in Arabidopsis,and the molecular regulation mechanism participating in stress response was relatively simple.Finally,the research direction and application prospect of wheat NAC transcription factor were prospected.The present paper could provide references for genetic improvement of wheat stress resistance more conveniently and efficiently.
