a, Comparison of the reaction pathways of anthocyanin glycosylation in the rose and in other plants: the rose glucosyltransferase RhGT1 catalyses two reactions instead of one. 3-GT, glucosyltransferase specific for the hydroxyl group at position 3 on the anthocyanidin molecule. b, Molecular phylogenetic tree based on the amino-acid sequences of members of the plant glucosyltransferase superfamily. Sequences were aligned by using the multiple alignment program Clustal W; the tree was constructed by the neighbour-joining method. Numbers indicate bootstrap values greater than 800.
