Abstract

Flavanone 3-hydroxylase (EC 1.14.11.9, F3H) plays a key role in anthocyanin biosynthesis, and sugars enhance anthocyanin accumulation and F3H expression in some other plants. However, information about the relationship between sugars, anthocyanin accumulation and F3H expression in grape berries has been little reported. Present experiment was done with sliced grape berry system. The optimum fruit developmental stage, sugar concentration, and incubation time in sugar induction anthocyanin accumulation and F3H expression were determined. Mannose and 2-deoxyglucose, glucose analogs known to be phosphorylated by hexokinase but are poorly metabolized, obviously induced the anthocyanin accumulation and F3H expression, whereas 3-O-methylglucose and 6-deoxyglucose, glucose analogs transported inside the cell but not substrates for hexokinase, did not induce them. Glucosamine and mannoheptulose, the specific inhibitors of hexokinase, blocked the activation induced by sugar on both anthocyanin accumulation and F3H expression.
