Abstract:

The pathway and genes of anthocyanin biosynthesis in ornamental plants were discussed in this paper. Factors affecting pigmentation included anthocyanin structures ,pH value in cell sap of petals, co-pigmentation, metal chelates, the shape of epidermal cells, and so on. Modification of flower color using genetic engineering was also summarized. It was suggested that new flower color could be created by regulating those factors that affected pigment and probing anthocyanin biosynthetic genes.

Key words: Anthocyanin, Biosynthetic pathway, Genetic engineering, Flower color expression
