CYTOCHROME B5 FROM PETUNIA

摘要

The present invention relates generally to a plant regulatory gene and derivatives and homologues thereof. More particularly, the present invention provides a nucleic acid molecule comprising a sequence of nucleotides or complementary sequence of nucleotides, the expression of which, modulates or otherwise facilitates activity of a cytochrome P450 protein in plant cells and tissues including petals, flowers, stems, leaves and seeds. Even more particularly, the nucleic acid molecule of the present invention encodes a cytochrome b5 or a mutant, part, fragment, portion, functional and/or structural equivalent or homologue thereof or agonist or antagonist thereof involved in modulating or otherwise facilitating activity of a dihydrokaempferol (DHK) hydroxylating enzyme such as but not limited to flavonoid 3', 5'-hydroxylase. The present invention further provides transgenic plants or parts thereof or cells of transgenic plants as well as cut or severed flowers or stems from transgenic plants.
