植物花青素合成与基因调控(英文)

文章在阐述植物花青素生物化学合成的基础上,综述了植物花色素苷合成的基因调控及环境、激素化学物质等外在因子对花青素基因调控的影响。结果表明:在植物花青素代谢中,温度、光照、紫外线、施肥状况、激素水平等因素能诱发花青素合成的调节基因或反义基因的表达,从而诱导或抑制了花青素的合成。在调控基因中,一些对花青素合成的结构蛋白表达产生促进作用,一些则具有抑制效应。不同外在因子激活或抑制调控基因的种类与数量不同,因此,产生了不同的花青素组型或相同组型的不同配比,使植物器官表现不同的颜色。

Plant Anthocyanin Synthesis and Gene Regulation

This paper aims to explain the biochemistry of anthocyanin synthesis based on an overview of plant anthocyanin synthesis genes and environmental factors in the regulation of anthocyanin metabolism.The results show that:① The metabolism of anthocyanins in plants is affected by the temperature,light,ultraviolet,fertilization status,hormone levels and other factors,which affect the military anthocyanin biosynthetic genes,and then induce or inhibit the synthesis of anthocyanins.② In the regulation of genes,some of the structural genes of anthocyanin synthesis showed promoting effect,while others showed inhibitory effect.At different environmental conditions,the regulation of gene activation and inhibition of the amount of different regulatory genes that anthocyanin accumulation is different,and cause different colors of plant-organs production.③ In different environmental factors or hormones induced to produce the same or different regulation of gene expression changes in regulatory genes,resulting in several different anthocyanins or anthocyanin ratio changes,so that the color of plant organs in different colors.
