摘要
R2R3-MYB(2R-MYB)是最大的MYB亚家族,在植物的生长发育及调控特有的生理进程中发挥重要作用,其成员广泛参与了园艺植物的生长发育、初生和次生代谢物质的合成、逆境响应以及激素信号传导.目前,已有70余种植物进行了全基因组水平的R2R3-MYB基因家族鉴定分析.基于此,本研究总结了R2R3-MYB转录因子家族成员的基因结构特点,并探讨了其在园艺植物品种创新和品质提升过程中发挥的功能作用,重点总结了 R2R3-MYB成员在30余种园艺植物次生代谢物质合成方面的调控作用.预期结果将有助于阐述R2R3-MYB基因家族的进化和功能多样性机制,同时为解析其在调控植物特殊代谢物合成的分子机制方面提供重要参考.
Abstract
R2R3-MYB(2R-MYB)is the largest MYB subfamily,which plays an important role in plant growth and regulation of unique physiological processes.Its members are widely involved in the growth and development of horticultural plants,synthesis of primary and secondary metabolites,stress response and hormone signaling.At pre-sent,the R2R3-MYB gene family has been identified and analyzed at the whole genome level in more than 70 plant species.Base on this,this study summarizes the gene structure characteristics of R2R3-MYB transcription factor family members,and discusses their functional roles in the process of variety innovation and quality improvement of horticultural plant,focusing on the regulatory role of R2R3-MYB members in the synthesis of secondary metabo-lites in more than 30 horticultural plants.The result are expected to elucidate the evolutionary and functional diversi-ty mechanisms of the R2R3-MYB gene family,and provide important references for the molecular mechanisms reg-ulating the synthesis of specific metabolites in plants.
