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.

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.

Abstract: The purpose of the present invention is to provide a breeding method for a plant having a blue flower color with a simpler blue color development controlling technique, without requiring complex mechanisms for blue color development that have been previously presented and techniques reproducing such mechanisms. Delphinidin-based anthocyanins, in which the both 3? and 5?-positions of the anthocyanin B-ring have been glycosylated, and flavone glycosides or flavonol glycosides as copigment are made to coexist in the cells of flower organ such as petals.

Abstract: There is provided a novel Campanula flavonoid 3?,5?-hydroxylase gene, and a plasmid comprising the gene under the control of the cauliflower mosaic virus 35S promoter.

Abstract: A novel promoter useful for altering the color of flowers of a plant, which is selected from the group consisting of: (1) a nucleic acid which comprises the nucleotide sequence represented by SEQ ID NO: 20, SEQ ID NO: 12 or SEQ ID NO: 21; and (2) a nucleic acid which maintains the same promoter activity as that of the nucleotide sequence represented by SEQ ID NO: 20, SEQ ID NO: 12 or SEQ ID NO: 21, and which comprises a nucleotide sequence that is produced by modifying the original nucleotide sequence by the addition, deletion and/or substitution of one or several nucleotide sequences, or can hybridize with a nucleotide acid comprising a nucleotide sequence complementary to the original nucleotide sequence under highly stringent conditions, or has a 90% or more sequence identity to the original nucleotide sequence.

Abstract: A method for producing a rose characterized by artificially suppressing the rose endogenous metabolic pathway and expressing the pansy gene coding for flavonoid 3?,5?-hydroxylase.

Abstract: A method of acylating the 3? position of anthocyanin using an enzyme that transfers an aromatic acyl group to a sugar at the 3? position of anthocyanin or a gene encoding the enzyme.
