Abstract
Transgenic plants with blue flower color, or their inbred or outbred progeny, or their propagules, partial plant bodies, tissues or cells, are provided. A buckwheat-derived C-glucosyltransferase (CGT) gene or its homolog is transferred into a host plant to cause delphinidin-type anthocyanins and flavone mono-C-glycosides to be copresent in the plant cells.
Claims11
A buckwheat-derived C-glucosyltransferase (CGT) gene or its homolog, wherein:
- the buckwheat-derived CGT gene or its homolog is
- a polynucleotide consisting of the nucleotide sequence as set forth in SEQ ID NO:
- 11.
A vector comprising a buckwheat-derived CGT gene or its homolog, wherein the buckwheat-derived CGT gene or its homolog is selected from the group consisting of:
- (a) a polynucleotide consisting of the nucleotide sequence as set forth in SEQ ID NO:
- 11;
- (b) a polynucleotide that encodes a protein consisting of the amino acid sequence as set forth in SEQ ID NO:
- 12;
- and
- (c) a polynucleotide that encodes a protein having an amino acid sequence with at least 98% identity with respect to the amino acid sequence as set forth in SEQ ID NO:
- 12 and having the same activity as a protein encoded by the polynucleotide of (b), and
- wherein the vector further comprises a flavanone 2-hydroxylase (F2H) gene or its homolog, and a dehydratase (FDH) gene or its homolog.
