additional information | loss of enzyme activity leads to accumulation of 3,5-di-O-(beta-glucopyranosyl)pelargonidin 6''-O-4,6'''-O-1-cyclic malate instead of 3,5-di-O-(beta-glucopyranosyl)cyanidin 6''-O-4,6'''-O-1-cyclic malate, the only difference between these two anthocyanins is a hydroxyl grouppresent at the 3' position in the B-ring of aglycone. Loss of enzme results in a color change in buds from purple to deep pink. Mutation is due to an active hAT type transposable element, designated Tdic101. The color change is attributed to Tdic101 insertion into the second intron of flavonoid 3'-hydroxylase | Dianthus caryophyllus |
