光影响植物花青苷合成研究

Effect of Light on Anthocyanin Synthesis in Plant

近几年来,对于环境因子影响花青苷合成的研究已有相关报道。现基于对花青苷合成影响最大的光因子,结合国内外研究,综述了光照时间、光照强度和不同光质对植物花青苷合成途径中相关酶活性的调节作用、相关基因的调控作用以及植物的呈色反应的影响,指出对于大多数植物而言,光照时间越长,越有利于花青苷的合成,植物呈色效果明显;光照促进植物花青苷合成和积累,光强越大,提高花青苷合成途径中相关酶活性,促进相关基因上调表达以及促进植物花青苷的积累,呈色效果明显;在不同的光质中,对合成花青苷最有效的是蓝光和紫外光,可以提高酶活性,增强相关基因的表达,促进植物呈色。此外,还分析了目前花青苷光环境研究存在的问题,为今后研究提供新思路和新方向。

In recent years,there were some comprehensive descriptions of the environmental factors＇ influence on anthocyanin synthesis.Therefore,based on light factor the major impact,combining with the relative literatures,the paper reviewed the effects of illumination time,light intensity and different light quality on the activity of the enzyme,the expression of genes and the color reaction of plants.The paper pointed out that the longer the illumination time,the stronger illumination intensity and blue and ultraviolet light were more effective to the biosynthesis and accumulation of anthocyanins,to improve the enzyme activity and to promote the genes expression in most plants.In addition,it also analyzed the problems unsolved in this field,in order to provide new ideas for future study work.
