摘要
转录因子(transcription factor,TF)是一类能够与特定部位结合,调控目的基因特定表达的具有特殊结构的蛋白质分子。NAC(NAM、ATAF1/2、CUC1/2)转录因子作为植物特有的一类转录因子家族,由保守的N端结构域和高度可变的C端转录激活域组成,参与植物生长发育、生物及非生物胁迫等反应过程,在植物花的发育过程中具有重要的调控作用。本文就NAC转录因子的发现、结构及其对花药发育、其他花器官发育、开花时间的调控作用等方面进行总结,以期为解析NAC转录因子在植物花发育中的调控机制以及完善调控网络提供理论依据。
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.
