Glycosyltransferases belong to a super gene family that catalyze glycosylation. Glycosylation modifications could enrich the structure of anthocyanidins,regulate its water solubility,stability and transportability,which are considered as important steps for petal color determinant. In this research,we reviewed the categories,biochemical and molecular biology of glycosyltransferases involved in the pigment metabolism in ornamental plants. In addition,the effects of some glycosyltransferases in the pigmentation of differently colored petals,such as blue-violet,orange to purplish red and yellow,are summarized. Finally,further research hotspots of pigmentation related glycosyltransferases are prospected. The results are expected to provide a reference for further understanding of the mechanism of glycosylations,and shed lights to the improvement of ornamental plant flower color through molecular breeding strategy.

Key words: ornamental plant, flower color, glycosyltransferase, functional characterization
