Abstract: Anthocyanidin is the material basis of the plant flowers showing different colors, its biosynthetic pathway is mainly controlledby Chalcone synthase, chalcone isomerase, flavanone 3-hydroxylase, flavonoid3'-hydroxylase, flavonoid 3', 5'-hydroxylase dihydroflavonol4-reductase, anthocyanidin synthase and flavonoid 3-O-glucosyltransferase. The biosynthesis pathway of anthocyanidin, core enzyme’s crystalstructure, modification of flower pigment were introduced in this review, discussed the existing issues in transformation of flower pigment and putin perspective.
