NAC 转录因子:参与植物诸多生命过程的调控因子.

The NAC(NAM, ATAF1 / 2, CUC2) protein family is one of the largest protein families in plants, and its members are detected in many plants. The NAC protein family is involved in the regulation of many plant life processes as a transcriptional regulator. NAC transcription factors (NAC TFs) generally consists of a special N-terminal DNA binding domain and a variety of C-terminal transcriptional activation / inhibition regions. The number of NAC TFs is very large and their functions are diverse, which plays an important role in regulating plant life activities. Therefore, it is of great significance to explore their biological functions and molecular regulatory networks for improving plant agronomic traits. In recent years, the research on NAC TFs has been hot. This paper systematically reviewed the research status, structural characteristics, action mode and evolution process of NAC TFs, as well as its regulation of specific plant life activities including secondary growth, biosynthesis, biotic / abiotic stress, hormone response, organ senescence, etc., and prospected its research trend.
