2.4.1.299 additional information the enzyme expression is restricted to petals, no activity in leaves and stems, overview 720677 2.4.1.299 petal AA5GT expression and AA5GT activity are restricted to carnation petals that have anthocyanin glucosylated at the 5 position, expression analysis, overview 723196 2.4.1.299 petal expression of Dc AA5GT in developing carnation petals is highest at early stages, AA5GT activity and anthocyanin accumulation continue to increase during later stages. Neither Dc AA5GT expression nor AA5GT activity is observed in the petals of mutant carnations, these petals accumulate anthocyanin lacking the glucosyl moiety at the 5 position 720677
