植物NAC转录因子的研究进展

The Research Progress of NAC Transcription Factors in Plant

NAC转录因子是近些年来新发现的植物特有的转录调控因子,其N端含有高度保守的NAC结构域,在植物的生长发育、器官建成、逆境胁迫以及作物的品质改良中具有重要作用。主要介绍了植物NAC转录因子结构特点、生物学功能、作用机制等方面的最新研究进展进行综述。

NAC transcription factors are the new type transcription regulatory factors discovered in recent years,which are unique to plants. They contain a highly conserved NAC domain in N-terminal ends. It was reported that NAC transcription factors play important roles in multiple biological functions such as development, organs foundation, responses to stresses, and improving the quality of crops. This article reviewed characters of structure, biological function, mechanism of expression and regulation of plant NAC transcription factors, as wall as the recent, research progress.
