摘要
类黄酮是一类具有“黄烷”骨架的数千种衍生产物的次生代谢物质,其生物合成通路错综复杂,部分通路和相关蛋白酶已被解析和鉴定。类黄酮在植物的生长发育、花和果实的品质形成中起到重要作用。研究表明,植物类黄酮在各类胁迫下响应,有效提高了植物应对胁迫的耐性和抗性。本文综述了类黄酮在植物中的生物合成通路和分子调控机制,类黄酮在植物应对不同胁迫时的响应和作用机制,以及类黄酮未来研究的发展方向,以期为定向培育高抗性、具备深加工和产品开发的园艺作物品种提供理论支撑。
Flavonoids are a class of secondary metabolites with‘flavan’skeleton and thousands of derivatives.The biosynthetic pathways of flavonoids are complicated,and some of them and related enzymes have been analyzed.Flavonoids play important roles in the growth and development of plants and the formation of flowers and fruits.Studies revealed that flavonoids can response to stresses and improve the tolerance and resistance of plants.This article reviews the biosynthetic pathways and molecular regulation mechanism of flavonoids in plants,the response of flavonoid pathways to different stresses,the main roles and mechanisms of flavonoids,and the future research directions.Thus,this article is expected to providing theoretical support for the targeted cultivation of horticultural crop varieties with highly resistant,deep processing,and product development.
