The influence of the gene Pr on flavonoid 3'-hydroxylase activity in maize is described. Specific activities are presented for the hydroxylase in seedlings and aleurone tissue homozygous dominant and recessive and heterozygous for Pr. Specific activity levels in both tissues increased in a nearly ...

Flavonoid 3′,5′-hydroxylase (F3′5′H) is a cytochrome P450 enzyme (Cyt P450) that catalyzes the 3′,5′-hydroxylation of dihydroflavonols, the precursors of purple anthocyanins. Species such as rose and carnation lack F3′5′H activity and are, therefore, unable to generate purple or ...

FlavonoidGenecloningExpressionBlackcurrantFlavonoid 3'-hydroxylase(F3' H) and 3',5'-hydroxylase(F3'5' H) generate precursor molecules for the synthesis of cyanidin-based anthocyanins(red) and delphinidin-based anthocyanins(blue to purple) in Ribes nigrum L.(black currant). In this study, full-...
FLAVONOIDSFlavonoid 3-hydroxylase (F3H) catalyzes hydroxylation at the 3 position of the B ring of flavonoids. F3H is associated with the seed coat and pubescence color, antioxidant properties, and chilling stress tolerance of soybean [Glycine max (L.) Merr.]. In this study, we found that ...

Furthermore, the unigenes encoding chalcone isomerase (CHS), flavanone 3-hydroxylase (F3H), flavonoid 3'-monooxygenase (F3'H), dihydroflavonol 4-reductase (DFR), leucoanthocyanidin dioxygenase (LDOX), and flavonol 3-O-glucosyltransferase (UF3GT) were found to be significantly up-regulated in the...
More particularly, the protein involved in flavonoid biosynthesis is selected from the group consisting of TRANSPARENT TESTA 12 (TT12), TRANSPARENT TESTA GLABRA 1 (TTG1), TRANSPARENT TESTA 2 (TT2), TRANSPARENT TESTA 8 (TT8), leucoanthocyanidin dioxygenase (LDOX), cinnamate-4-hydroxylase (C4H),...
