Transcription factors, the proteins with special structures, can bind to specific sites and regulate specific expression of target genes. NAC (NAM, ATAF1/2, CUC1/2) transcription factors, unique to plants, are composed of a conserved N-terminal domain and a highly variable C-terminal transcriptional activation domain. NAC transcription factors are involved in plant growth and development, responses to biotic and abiotic stresses and other processes, playing a regulatory role in flower development. In this paper, we reviewed the studies about NAC transcription factors in terms of discovery, structure, and regulatory roles in anther development, other floral organ development and flowering time. This review will provide a theoretical basis for deciphering the regulatory mechanism and improving the regulatory network of NAC transcription factors in flower development.
转录因子是具有特殊结构的蛋白质,能够结合特定位点并调控靶基因的特异性表达。NAC(NAM、ATAF1/2、CUC1/2)转录因子是植物特有的,由一个保守的N端结构域和一个高度可变的C端转录激活结构域组成。NAC转录因子参与植物生长发育、对生物和非生物胁迫的响应等过程,在花发育中发挥调控作用。本文从发现、结构以及在花药发育、其他花器官发育和开花时间方面的调控作用等方面对NAC转录因子的研究进行了综述。本综述将为解析NAC转录因子在花发育中的调控机制及完善其调控网络提供理论依据。
