摘 要:

花青素苷是一类水溶性的类黄酮类化合物, 广泛存在于植物的根、茎、叶、花、果实、种子中, 使这些组织器官呈现出红、蓝、紫等不同的颜色, 同时有利于提高植株繁殖后代和抵御不良环境的能力。本文着重对花青素苷的生物合成途径、花青素苷的呈色机理及环境因子对花青素苷生物合成的调控等方面进行了综述, 并对今后的研究方向进行了展望, 以期更好地解析植物体内花青素苷生物合成的分子调控机制, 为丰富植物花、叶、果实等组织器官的颜色种类、定向改变植物体内花青素苷的含量及栽培设施的改进提供参考。

Abstract:

Anthocyanins, widely existed in the roots, stems, leaves, flowers, fruits and seeds of plants in nature, are a family of water-soluble flavonoids. They can give tissues and organs different colors, such as red, blue and purple, and can also be conducive to improve the abilities of plants to reproduce offspring and resist adverse environments. In this paper, we review the biosynthetic pathway of anthocyanin, mechanism of anthocyanin coloration and regulation of environmental factors on anthocyanin biosynthesis, and propose the direction for the future studies. This paper would make us better understanding the molecular regulation mechanism of anthocyanin biosynthesis in plants and provide references for enriching the color types of flowers, leaves and fruits in plants, directionally changing the contents of anthocyanins, and improving cultivation facilities.

Key words: anthocyanin; biosynthesis; coloration mechanism; environmental factor
