Anthocyanin modification in Arabidopsis

Anthocyanins are produced by a branch of the flavonoid pathway. They give plants a colorful world from red, purple to blue pigments, and play an important role in pollination and seed dispersal. The diversities of modification groups, numbers and positions not only affect the color and stability of anthocyanins, but also largely expand their species. In recent years, enzymes involved in anthocyanin modifications have been widely reported in different species. Based on the sequenced genome, short life span and distinct anthocyanin composition, Arabidopsis thaliana has become an ideal material to study the anthocyanin modification pathway. This review summarized the progress made towards anthocyanin modification pathways in Arabidopsis.
