园艺作物花青素合成调控研究进展

Research Progress on the Regulation of Anthocyanin Synthesis in Horticultural Crops

花青素是一类保护植物免受生物和非生物胁迫的重要次生代谢产物,因其赋予植物丰富的色彩和对人体的保健功能而受到广泛关注。花青素合成调控机理的相关研究是目前园艺作物分子生物学研究的前沿课题,对于园艺作物花青素含量的提高、种质品质的提升等具有重要的意义。结合国内外园艺作物中花青素生物合成调控方面的最新研究进展,介绍了环境因素、酶与激素、DNA甲基化与泛素化和调控基因等对花青素生物合成的作用,以及花青素抵御外界胁迫的功能机制,综述了近年来园艺作物中花青素生物合成调控的研究成果,以期利用基因工程为提升园艺作物的色彩丰富度提供理论参考。

Anthocyanin is an important secondary metabolite that protects plants from biotic and abiotic stress.It has received widespread attention because of its rich colors to plants and its benefit to human health.The related research on the regulation mechanism of anthocyanin synthesis is the current frontier subject of molecular biology of horticultural crops,which has important significance for the improvement of anthocyanin content and germplasm quality of horticultural crops.This article com‐bined the latest research progress in the regulation of anthocyanin biosynthesis in horticultural crops at home and abroad,and introduced the effects of environmental factors,enzymes and hormones,DNA methylation and ubiquitination,and regulatory genes on anthocyanin biosynthesis,and the functional mechanism of anthocyanins against external stresses.The research results of anthocyanin biosynthesis regulation in horticultural crops in recent years were reviewed,in order to using genetic engineering to provide a theoretical reference for enhancing the color richness of horticultural crops.
