Flavonoids are the most abundant secondary metabolites in grape. These compounds play vital roles in grape growth and development,resistance to ultraviolet radiation and diseases/insects,berry coloration and flavor quality,as well as nutritional values. Grape berries possess various types of flavonoids,which show variety-,tissue-,and development-specific accumulation characteristics. Flavonoid metabolism in grape is mainly regulated by UDP-glucose:flavonoid 3-O-glycosyltransferaseUFGT)and MYBA1 genes,and also affected by a variety of biotic and abiotic factors. The review summarizes recent data related to the flavonoid metabolism from the aspects of biological functions,composition and accumulation characteristics,biosynthesis and regulation mechanisms,and influencing factors. Finally,the future research directions of grape flavonoid metabolism are also put forward from the aspects of perfecting flavonoid content database,uncovering important gene functions,analyzing metabolic regulation networks,and exploring the interaction mechanisms of multiple factors.

Key words: grape, flavonoids, secondary metabolism, fruit quality
