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.
