Abstract
Provided is: a transgenic plant that has a modified flower color; a self- or cross-fertilized descendant of the transgenic plant; or a propagule, a portion of a plant body, tissue, or cells from the transgenic plant or the self- or cross-fertilized descendant of the transgenic plant. The present invention causes both anthocyanin delphinidin and a flavone C-glycoside that is methylated at the hydroxyl group at the 7 position to be present in the cells of a plant.

A vector comprising a polynucleotide selected from the group consisting of the following (a), (c) and (e):
- (a) a polynucleotide consisting of the nucleotide sequence of SEQ ID NO:
- 34;
- (c) a polynucleotide encoding a protein consisting of the amino acid sequence of SEQ ID NO:
- 35;
- and
- (e) a polynucleotide encoding a protein consisting of an amino acid sequence with at least 90% identity to the amino acid sequence of SEQ ID NO:
- 35 and having activity of transferring a methyl group to the hydroxyl group at position 7 of flavone C-glycoside, and
- which further comprises a flavone synthase (FNS) gene or its homolog, and a flavone C-glycosylase (CGT) gene or its homolog.
