part of flavonoid biosynthetic pathway
physiological function

the enzyme introduces a hydroxyl group at 3' position of the B-ring of the flavonoid molecule leading to the formation of 3',4'-hydroxylated flavonoids; the enzyme introduces a hydroxyl group at 3' position of the B-ring of the flavonoid molecule leading to the formation of 3',4'-hydroxylated flavonoids; the enzyme introduces a hydroxyl group at 3' position of the B-ring of the flavonoid molecule leading to the formation of 3',4'-hydroxylated flavonoids
physiological function
-
enzyme expression is associated with anthocyanin accumulation in five different sweet potato cultivars tested
physiological function
-
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 group present at the 3' position in the B-ring of aglycone. Loss of enzyme 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

recombinant expression of the flavonoid 3',5'-hydroxylase, EC 1.14.13.88, from Petunia sp. in Dendrathemum grandiflora plants leads to competition of the endogenous flavonoid 3'-hydroxylase with the recombinant enzyme for the same substrates in the flavonoid biosynthetic pathway leading to a change in flower petal colors, phenotype, overview

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

enzyme expression is under control of pericarp color1, P1. The P1 controlled 3-deoxyanthocyanidin and C-glycosyl flavone defence compounds accumulate at significantly higher levels in Pr1 silks as compared to pr1 silks. By virtue of increased maysin synthesis in Pr1 plants, corn ear worm larvae fed on Pr1/P1 silks show slower growth as compared to pr1/P1 silks
