MYB转录因子调控园艺植物芳香化合物合成研究进展

摘要/Abstract

摘要：

MYB转录因子作为植物中最大的转录因子家族之一，在调控园艺植物芳香化合物生物合成过程中发挥着核心作用。近年来，研究已明确MYB成员通过直接结合结构基因启动子或与bHLH、WD40等蛋白互作形成复合体，从而精确调控萜类、苯丙素类及脂肪酸衍生物等关键芳香物质的合成代谢。本文中系统综述了近十年来MYB在芳香化合物合成调控网络中的功能与机制，重点总结了其在模式植物及重要园艺作物中的调控路径，并对环境因子与MYB介导的香气合成调控提出了展望。

关键词: MYB, 转录因子, 调控, 芳香化合物, 园艺植物

Abstract:

As one of the largest transcription factor families in plants，MYB transcription factors play a central role in regulating the biosynthesis of aromatic compounds in horticultural crops. Recent studies have clarified that MYB members precisely regulate the synthetic metabolism of key aromatic substances，including terpenoids，phenylpropanoids，and fatty acid derivatives，by directly binding to structural gene promoters or forming complexes through interactions with proteins such as bHLH and WD40. This review systematically summarizes the functions and mechanisms of MYBs in the aromatic synthesis regulatory network over the past decade，focusing on their regulatory pathways in model plants and major horticultural crops. It also proposes future directions for the regulation between environmental factors and MYB-mediated aroma synthesis.

Key words: MYB, transcription factor, regulation, aromatic compounds, horticultural plants
