摘　　要：NAC(NAM、ATAF1/2、CUC2)转录因子家族是植物中最大的蛋白家族之一,在多种植物中均发现其家族成员。NAC转录因子(NAC transcription factors,NAC TFs)一般由保守的N端特殊的DNA结合域以及多样的C端调控结构域组成,其数量十分庞大且功能多种多样,主要通过调控靶基因的表达水平参与调控诸多生命过程,进而调控植物的次生代谢产物合成、生长发育和应激反应,探究其生物学功能及分子调控机制,对改良植物农艺性状具有重要意义。系统综述了NAC TFs的研究现状、结构特点、作用模式和进化历程,及其对植物生命活动的调控包括次生生长、生物合成、生物/非生物胁迫响应、器官衰老等,旨在为改良植物农艺性状提供理论基础。The NAC(NAM,ATAF1/2,CUC2)protein family is one of the largest protein families in plants,and its members are detected in many plants.The NAC protein family is involved in the regulation of many plant life processes as a transcriptional regulator.NAC transcription factors(NAC TFs)generally consists of a special N-terminal DNA binding domain and a variety of C-terminal transcriptional activation/inhibition regions.The number of NAC TFs is very large and their functions are diverse,which plays an important role in regulating plant life activities.Therefore,it is of great significance to explore their biological functions and molecular regulatory networks for improving plant agronomic traits.In recent years,the research on NAC TFs has been hot.This paper systematically reviewed the research status,structural characteristics,action mode and evolution process of NAC TFs,as well as its regulation of specific plant life activities including secondary growth,biosynthesis,biotic/abiotic stress,hormone response,organ senescence,etc.,and prospected its research trend.
