摘　要：

NAC转录因子是植物特有的一类转录因子, 其共同特点是在N端含有一段高度保守的约150个氨基酸组成的NAC结构域, 而C端为高度多样化的转录调控区。NAC转录因子是具有多种生物功能的新型转录因子, 在植物细胞次生壁的生长、植物顶端分生组织形成、植物侧根发育等生长发育过程以及作物的品质改良中具有重要作用。此外, 研究表明NAC转录因子在植物抗逆反应中也具有重要的调控作用。本文综述了近年来NAC转录因子家族在植物抗逆中的研究进展。

Abstract:

NAC transcription factors belong to a unique class of transcription factors in plants. The common characteristic of the NAC proteins is the presence of a conserved NAC domain, comprising of about 150 amino acids in N-terminals and a highly variable transcriptional regulation region in C-terminals. NAC transcription factors play important roles in multiple biological processes such as secondary cell wall, plant apical meristem formation, lateral root development and crop quality improvement. Besides, it has been shown that NAC transcription factors play an indispensable role in plant resistance to adverse reaction. In this paper, we reviewed the recent study progress on NAC transcription factors family in stress responses in plants.
