摘要：

为了进一步阐述花青素在植物体内的合成机制,了解影响花青素合成的各类因子及其互作方式,本文归纳了调控花青素合成的内部因子和外部因素,总结了光、温度、糖类和激素等调控花青素生物合成的环境因素。围绕花青素的合成通路,就通路中的结构基因及其上游转录因子相关研究进行了总结。研究得出在植物中,各类外部因素和内在因子,通过主要的转录因子调控结构基因,影响花青素在植物体内合成与积累,维持植物体内花青素的动态平衡,这种调节机制既包括正向调控也包括负向调控。指出花青素的代谢途径逐渐完善,越来越多结构基因和转录因子的功能将被验证并被应用到观赏植物性状的基因工程改良的实践中。

Abstract:

To elaborate the mechanism of anthocyanin biosynthesis in plants and understand the various factors affecting anthocyanin synthesis as well as their interaction, we summarize the internal and external regulatory factors and concluded the environmental factors such as light, temperature, carbohydrate and hormone. Around the anthocyanin biosynthesis pathway, the structural genes in the pathway and its upstream transcription factors are described and analyzed. This study concludes that in plants, all kinds of external and internal factors regulate structural genes through the main transcription factors, affect the biosynthesis and accumulation of anthocyanins in plants, and maintain the dynamic balance of anthocyanins in plants. This regulation includes both positive and negative regulation. In summary, metabolic pathway of anthocyanins is gradually improved, at the same time, novel structural genes and transcription factors will be evaluated and used in genetic engineering improving the characteristics of ornamental plants.

Key words: anthocyanin, mechanism, biosynthesis, environmental factors, structural genes, transcription factors
