Patent ID: 8314291

Claim:
A method for producing a dicotyledon with modified flower morphology, comprising the steps of: obtaining a transformed cell by introducing a chimeric DNA molecule into a dicotyledonous cell; and regenerating a transformed plant from said transformed cell, wherein said chimeric DNA molecule comprises is a DNA molecule encoding a transcription factor and a DNA molecule encoding a functional peptide converting said transcription factor into a transcription repressor wherein the chimeric DNA molecule is expressed which results in the plant having a modified flower petal morphology as compared to a non-transformed plant, and wherein said DNA molecule encoding said transcription factor is selected from the group consisting of: (a) a DNA molecule encoding the amino acid sequence of SEQ ID NO: 4; (b) a DNA molecule comprising the nucleotide sequence of SEQ ID NO: 3; (c) a DNA molecule encoding the amino acid sequence of SEQ ID NO: 4 including substitution, deletion, insertion and/or addition of 1 to 10 amino acids, and (d) a DNA molecule encoding an amino acid sequence having an identity of not less than 90% to the amino acid sequence of SEQ ID NO: 4, wherein said dicotyledon belongs to sympetalae.
