摘　　要：CUC (CUP-SHAPED COTYLEDON)是植物中特有的一类转录因子,属于NAC (NAM/ATAF/CUC)超家族的一个亚族。该家族成员在植物器官边界分离、茎尖分生组织形成、叶片形态和花器官发育中发挥重要作用。本文主要对CUC亚家族基因的起源、进化、结构、分类、生物学功能及其参与的分子代谢通路、激素通路、表观遗传修饰调节过程进行综述性介绍,并对近年来对该基因家族的最新研究成果进行总结,以期为深入研究该转录因子在生长发育过程以及在不同物种中的功能提供参考和帮助。CUC(CUP-SHAPED COTYLEDON) is a family of plant-specific transcription factors, belonging to a subfamily of the NAC(NAM/ATAF/CUC) superfamily. Members of this family play important roles in plant organ boundary separation, shoot apical meristem formation, leaf morphology and floral organ development. This paper mainly reviews the origin, evolution, structure, classification and biological functions of CUC subfamily genes, as well as their molecular metabolic pathways, hormone pathways, and epigenetic modification regulation processes. The latest research progress on this gene family is summarized in order to provide reference and help for the further studies on the growth, development and functions of this transcription factor family in different species.
