摘　要：

花色素苷是决定高等植物花、果实、叶片和种皮颜色的主要色素, 其生物合成与积累过程受自身遗传背景和环境因子共同调控。光照是影响植物花色素苷生物合成的主要环境因子之一, 不同光质和强度的光对花色素苷合成的影响存在一定差异, 其中光质起更为关键的作用。本文重点从光受体、光信号转导及其与转录因子和结构基因互作的角度对光照调控花色素苷合成的整个过程进行了总结, 并对今后的研究方向进行了展望, 以期能为园艺植物新品种选育和栽培设施的改进提供参考。

Abstract:

Anthocyanins are the main pigments in flowers, fruits, leaves and seed capsules of higher plants. Biosynthesis and accumulation of anthocyanins were co-regulated by their genetic background and environmental factors. Light is one of the major environmental factors limiting anthocyanin biosynthesis in plant. Different light qualities and light intensities have different effects on anthocyanin accumulation, but light quality play an even more critical role. In order to provide references for breeding of new horticultural varieties and improving cultivation facilities, this review summarizes research progresses of photoreceptors, light signal transduction and interacting with transcription factors and structural genes in the entirely process of light-regulating anthocyanin biosynthesis, and proposes future research interests.
