ABSTRACT The NAC transcription factor (TF) is one of the largest families of TFs in plants and plays an important role in plant growth, development, and response to environmental stress. The structural and functional characteristics of NAC TFs have been uncovered in the past years, including sequence binding features of the DNA-binding domain located in the N-terminus and dynamic interplay between the domain located at the C-terminus and other proteins. Studies on NAC TF are increasing in number; these studies distinctly contribute to our understanding of the regulatory networks of NAC-mediated complex signaling and transcriptional reprogramming. Previous studies have indicated that NAC TFs are key regulators of the plant stress response. However, these studies have been for six years so far and mainly focused on drought and salt stress. There are relatively few reports about NAC TFs in plant cold signal pathway and no related reviews have been published. In this review article, we summarize the structural features of NAC TFs, the target genes, upstream regulators and interaction proteins of stress-responsive NAC TFs, and the roles NAC TFs play in plant cold stress signal pathway.

NAC转录因子在植物冷响应中的作用

摘要 NAC 转录因子（TF）是植物中最大的转录因子家族之一，在植物生长、发育和对环境胁迫的响应中起着重要作用。NAC TFs 的结构和功能特征在过去几年已经被发现，包括位于 N 端的 DNA 结合域的序列结合特征以及位于 C 端的域与其他蛋白质之间的动态相互作用。对 NAC TF 的研究越来越多；这些研究明显有助于我们理解 NAC 介导的复杂信号传导和转录重编程的调节网络。以前的研究表明 NAC TFs 是植物胁​​迫反应的关键调节剂。然而，这些研究迄今已有六年时间，主要集中在干旱和盐胁迫上。关于植物冷信号通路中 NAC TFs 的报道相对较少，也未发表相关评论。在这篇综述文章中，我们总结了 NAC TFs 的结构特征、逆境响应 NAC TFs 的靶基因、上游调节因子和相互作用蛋白，以及 NAC TFs 在植物冷胁迫信号通路中的作用。
