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、由约150个氨基酸组成的NAC结构域, 而C端为高度变异的转录调控区。研究表明, NAC转录因子不仅参与植物生长发育的调控, 而且在植物抗逆反应中具有重要的调控作用。文章着重介绍NAC转录因子在植物抗逆反应中的作用及其调控机制, 并简要讨论NAC转录因子生物学功能的研究方向。

Abstract: NAC transcription factors belong to a unique class of transcription factors in plants. The common characteristics of the NAC proteins are 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. Extensive studies have revealed that NAC transcription factors not only play important roles in plant growth and development, but also have functions in regulation of responses to biotic and abiotic stresses. In this minireview, we summarized the functions and mechanisms of the NAC transcriptional factors in plant abiotic and biotic stress responses. We also discussed future directions towards understanding the biological functions of the members of the NAC transcriptional factors in plants.

Key words: NAC transcription factor, biotic and abiotic stresses, regulation mechanism
