Abstract:

Plant MYB represents a large family of transcription factors that play extensive roles in regulating crucial biological processes. These include growth and developmental regulation, such as seed dormancy and germination, root development, secondary cell wall synthesis, tiller initiation and elongation, floral organ differentiation and development, panicle morphogenesis, seed development, and phytohormone metabolism. They are also key players in responses to biotic and abiotic stresses (e.g., diseases, insect pests, high temperature, low temperature, drought, high salinity, and UV damage), absorption and utilization of mineral nutrients (e.g., nitrogen, phosphorus, copper), and the synthesis of secondary metabolites (e.g., anthocyanins, flavonoids). This review systematically summarizes the protein structure and classification of MYB transcription factors, as well as the important agronomic traits they regulate. Future research directions are also discussed, including mining more MYB family genes in rice, deciphering the pleiotropic effects of MYB factors, identifying superior haplotypes, and promoting breeding applications through strategies such as promoter editing. The aim is to provide genetic resources and theoretical support for breeding rice varieties with high yield, improved quality, and enhanced stress resistance.

摘要:

植物MYB是一大类转录因子家族,广泛参与多种重要生物学过程的调控,包括种子休眠与萌发、根系发育、次生细胞壁合成、分蘖发生与伸长、花器官分化与发育、穗部形态建成、种子发育以及植物激素代谢等生长发育调节;同时在生物与非生物胁迫响应(如病虫害、高温、低温、干旱、高盐、紫外线损伤等)、矿质营养元素吸收利用(如氮、磷、铜等)以及次生代谢物合成(如花青素、黄酮类化合物)等方面也发挥关键作用。本文系统综述了MYB转录因子的蛋白结构、分类及其调控的重要农艺性状,并对未来研究方向进行展望,包括挖掘更多水稻MYB家族基因、解析MYB的一因多效性、发掘优良单倍型以及利用启动子编辑等技术推动育种应用,以期为水稻高产、优质和抗逆育种提供基因资源与理论支撑。
