Abstract
The present invention relates generally to transgenic flowering plants. More particularly, the present invention is directed to transgenic rose, carnation and chrysanthemum plants genetically modified to enable expression of flavonoid 3',5'-hydroxylase thereby permitting the manipulation of intermediates in the flavonoid pathway.
Claims38
A transgenic plant selected from rose, carnation and chrysanthemum, or progeny or flowering parts thereof wherein said transgenic plant is transformed with a genetic construct comprising a promoter from a gene encoding an enzyme of the flavonoid pathway operably linked to a gene encoding a flavonoid 3',5'-hydroxylase that hydroxylates dihydrokaempferol, and wherein said transgenic plant produces higher levels of anthocyanins derived from delphinidin relative to non-transgenic plants of the same species.
A method for producing a transgenic plant selected from rose, carnation and chrysanthemum, said method comprising introducing into said plant a gene construct comprising a promoter from a gene encoding an enzyme of the flavonoid pathway operably linked to a nucleic acid encoding a flavonoid 3'-5'-hydroxylase that hydroxylates dihydrokaempferol, wherein said transgenic plant produces higher levels of species.
