WebBlue flower colour was always associated with something unusual and desired. ... Enzyme is a member of cytochrome P450 protein family (P450s). It is a very diverse group of heme-containing oxidases, which catalyse NADPH- or NADH-dependent oxidation. F3'5'H was classified into CYP75A subfamily. WebJan 19, 1999 · Petunia, on the other hand, contains two loci, termed hf1 and hf2, that encode a Cyt P450 with F3'5'H activity. Here we report the identification of an additional petunia gene that is required for 3',5' substitution of anthocyanins and purple flower colors. It encodes a cytochrome b5 and is expressed exclusively in the flower.
WebFlower colour and cytochromes P450. Abstract Flavonoids are major constituents of flower colour. Plants accumulate specific flavo- noids and thus every species often … WebThere are 244 cytochrome P450 genes (and 28 pseudogenes) in the Arabidopsis genome. P450s thus form one of the largest gene families in plants. Contrary to what was initially thought, this family diversification results in very limited functional redundancy and seems to mirror the complexity of plant metabolism.
