摘要: 紫色芽叶茶作为特异的茶树种质资源,具有高花青素、芽叶紫红的特性,因而受到学者们的重视。植物的花青素合成途径及其关键基因的研究成为热点,目前,从不同物种中已克隆、鉴定了花青素合成和代谢相关的主要调节基因和结构基因。前人研究表明,花青素合成和代谢与环境密切相关,而光照是主要的影响因素,但其调控机理尚不明确。通过综述光照对其他紫色植物的花青素的调控,进一步探讨了光照对紫色芽叶茶花青素合成相关基因的调控,为研究茶树特异种质资源和生物技术育种提供依据。

Abstract: Purple shoots of tea as a specific tea germplasm with the characteristics of high anthocyanin and purplish red have earned the attentions from scholars. Studies on the biosynthesis pathway of anthocyanin and its key genes in plants have become a hot spot;currently the main regulatory genes and structural genes associated with anthocyanin synthesis and metabolism have been cloned and identified from different species. Previous studies have shown that anthocyanin synthesis and metabolism are closely correlated with the environment, and lighting is the major affecting factor, however its regulation mechanism is uncertain yet. Summarizing the regulation of lighting on anthocyanin in other purple plants, and further exploring the regulation of lighting on the genes related to anthocyanin synthesis in the purple shoots of tea provide the basis for the study of specific tea germplasm and breeding biotechnology.

Key words: purple shoots of tea, anthocyanin, synthetic pathway, lighting
