  The present invention provides novel protein and gene related to flavonoid O-methyltransferase (FOMT) and their uses therefore. The said protein having an amino acid sequence shown in SEQ ID NO: 3, or an amino acid sequence having deletion, substitution or insertion of one or plural amino acids in said amino acid sequence. The said gene comprising the nucleotide sequence shown in SEQ ID NO: 1, or a gene which hybridizes with said gene under stringent conditions and encodes a protein, which has anthocyanin 3′—O-methyltransferase or 3′,5′—O-methyltrasnferase activity. The present invention also provides a method for obtaining the transgenic plant used the above-mentioned gene.
