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
