摘要
NAC转录因子是近十几年发现的植物特有的转录因子,其N端独特的DNA结合域及C端的转录激活域在植物非生物胁迫应答中发挥重要的调控作用,从而使植物发生一系列生理生化变化,增强植物对非生物胁迫的抗性。基因表达的转录调控在植物适应环境和抵御逆境胁迫中起重要作用。现从NAC转录因子的结构特点和分类、在非生物胁迫相关抗性中的作用及其调控机理等方面总结前人的研究进展,提出存在的问题与未来发展趋势。
NAC transcription factors were plant-specific transcription factors found in the last decades.Because of its unique N-terminal DNA-binding domain and C-terminal transcriptional activation domain,it plays an important role in plant responses to abiotic stress,and leas to a series of physiological and biochemical changes in plants,then enhanced the resistance to abiotic stress.Transcriptional regulation of gene expression is a key for plant adaptation to the environment and to withstand adversity.In this article,research progress from the following aspects were summarized：the structural characteristics and classification of NAC transcription factor,the function of NAC transcription factors in abiotic stressrelated resistance in plant,the regulation mechanism,etc.Then it raised the problems and the future trends.
