摘　　要：MYB转录因子是植物中最大的转录因子家族之一,能够结合基因5’端上游特定核苷酸序列,协助RNA聚合酶催化DNA模板链转录成RNA,起到调控目的基因表达的作用。根据myb结构域分为4个亚类,其中大部分与植物生长发育、次生代谢及逆境胁迫密切相关。番茄作为重要的栽培作物,在生产及科学研究中具有重要地位。主要阐述MYB转录因子的结构特征、分类,以及在番茄生长发育、次生代谢、生物与非生物胁迫中调控作用,归纳总结国内外的研究成果,并对其进行了较为详细的介绍,为进一步开展番茄MYB转录因子的研究和利用提供了相关参考及新的思路。MYB transcription factor is one of the largest family of transcription factors in plants,which can bind specific nucleotide sequences upstream of the 5'terminal of genes.It can assist RNA polymerase to catalyze the transcription of DNA template chains into RNA,and play a role in regulating the expression of target genes.According to myb domain,MYB transcription factors can be divided into four subclasses,most of which are closely related to plant growth and development,secondary metabolism and stress.Tomato,as an important cultivated crop,plays an important role in production and scientific research.This paper mainly describes the structural characteristics and classification of MYB transcription factor,and its regulatory role in tomato growth and development,secondary metabolism,biological and abiotic stress.The research results at home and abroad were summarized and introduced in detail,which provided relevant reference and new ideas for further research and utilization of tomato MYB transcription factors.
