Abstract
Described are plants not naturally capable of reducing dihydrokaempferol and containing a DNA sequence inserted according to recombinant DNA techniques which DNA sequence encodes a protein with the enzymatic activity of a dihydroflavonol 4-reductase (DFR) with extended substrate specificity for dihydrokaempferol. Furthermore, methods for the production of said plants, recombinant vectors and the use of said plants for the breeding of plants and parts of plants with modified flower colour are described.
Claims6
A transgenic plant derived from a plant normally not capable of reducing dihydrokaempferol, where the transgenic plant is comprised of a chimeric DNA construct comprising in the 5' to 3' direction a heterologous promoter which is operably joined to a DNA sequence encoding dihydroflavanol 4-reductase which is operably joined to a transcription termination regulatory region such that the plant tissues containing the translation product of the DNA sequence are able to reduce dihydrokaempferol.
