Abstract:
A method of producing a transgenic plant exhibiting altered flower colour, said method comprising:(1) selecting a first plant which is incapable of synthesizing a DFR which acts on DHK, or produces reduced levels of DFR compared to a wild type plant, or produces a DFR with a reduced substrate specificity for DHK compared to DHQ or DHM; and(2) introducing into said first plant one or more genetic constructs comprising a nucleotide sequence encoding a F3'5'H and a nucleotide sequence encoding a DFR which acts on DHM but is either incapable of acting on DHK or has a greater substrate specificity for DHM than for DHK or DHQ, to produce said transgenic plant, wherein said transgenic plant has altered flower colour compared to said first plant.
