Abstract excerpt
Blue coloration in delphinium flowers arises from 7-polyacylated anthocyanins which are modified alternately with acyl and glucosyl residues at the 7 position of the aglycone. Previously, we identified two independent genes for acyl-glucose-dependent anthocyanin 7-(6-(p-hydroxybenzoyl)-glucoside) glucosyltransferases (AA7BG-GT); recombinant proteins from the two cDNAs were produced in Escherichia coli and showed...
