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 rose is produced in which an introduced gene is only present in a part of the cells thereof, such as cells of the L1 layer of flower petals, but is not present in germ cells such as pollen cells or ovule cells. Since the introduced gene is not propagated to other roses even when this rose is crossed with other roses, the possibility of dispersal of the introduced gene can be completely negated.

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.

Abstract: A novel flavonoid glucosyltransferase originating from rose, a nucleic acid encoding that enzyme, for example, a flavonoid glucosyltransferase having an amino acid sequence indicated in SEQ ID NO. 2 or SEQ ID NO. 4, a nucleic acid encoding that enzyme, a method for changing the color of a rose flower using that nucleic acid, and a rose plant capable of changing color, are provided.

Abstract: The invention provides a rose characterized by comprising a flavone added by a genetic modification method. The flavone is typically produced by expression of a transferred flavone synthase gene. The flavone synthase gene is, for example, a flavone synthase gene of the family Scrophulariaceae, and specifically it may be the flavone synthase gene of snapdragon of the family Scrophulariaceae, or the flavone synthase gene of torenia of the family Scrophulariaceae.

Abstract: The invention provides a rose characterized by comprising a flavone and delphinidin added by a genetic modification method. The flavone and delphinidin are typically produced by expression of a transferred flavone synthase gene and flavonoid 3?,5?-hydroxylase gene, respectively. The flavone synthase gene is, for example, a flavone synthase gene of the family Scrophulariaceae, and specifically it may be the flavone synthase gene of snapdragon of the family Scrophulariaceae, or the flavone synthase gene of torenia of the family Scrophulariaceae. The flavonoid 3?,5?-hydroxylase gene is, for example, the pansy (Viola×wittrockiana) flavonoid 3?,5?-hydroxylase gene.

Abstract: The invention provides a rose characterized by comprising a flavone and malvidin added by a genetic modification method. The flavone and malvidin are typically produced by expression of a transferred flavone synthase gene, pansy flavonoid 3?,5?-hydroxylase gene and anthocyanin methyltransferase gene. The flavone synthase gene is, for example a flavone synthase gene of the family Scrophulariaceae, and specifically it may be the flavone synthase gene of snapdragon of the family Scrophulariaceae, or the flavone synthase gene of torenia of the family Scrophulariaceae. The flavonoid 3?,5?-hydroxylase gene is, for example, the pansy flavonoid 3?,5?-hydroxylase gene. The anthocyanin methyltransferase gene is, for example, the methyltransferase gene of torenia of the family Scrophulariaceae.
