An enzyme catalyzing the transfer of the glucosyl moiety of UDP-glucose to the 5-hydroxyl group of cyanidin-3-rhamnosyl-(1 leads to 6)-glucoside has been demonstrated in petal extracts of Silene dioica plants. This glucosyltransferase activity was not detectable in green parts of these plants. The e
