摘要:
The present invention provides an enzyme which catalyzes a reaction to transfer sugar to a hydroxyl group at position 2′ of chalcones and a gene thereof, and preferably an enzyme which catalyzes a reaction to transfer glucose to a hydroxyl group at position 2′ of the chalcones. Furthermore, the invention provides a plant whose flower color has been changed using the glycosyltransferase. Using probes corresponding to conservative regions of the glycosyltransferase, some tens of glycosyltransferase genes having nucleotide sequences corresponding to the conservative regions were cloned from flower petal cDNA libraries of carnation and the like. Furthermore, each of the glycosyltransferase genes was expressed in Escherichia coli, activity to transfer glucose to position 2′ of the chalcone, i.e., the glycosyltransferase activity at position 2′ of chalcone was confirmed in an extract solution of the Escherichia coli, and it was confirmed that cloned genes encoded the glycosyltransferase at position 2′.

摘要:
Provided is a method for producing lilies containing a blue pigment (delphinidin) in the petals thereof by introducing a foreign gene into lilies. The method pertaining to the present invention is a method for producing lilies containing delphinidin in the petals thereof, including the following steps: introducing, into a lily, a F3′5′H gene derived from a campanula and comprising a nucleotide sequence encoding a peptide having flavonoid 3′5′-hydroxylase (F3′5′H) activity, such as a nucleotide sequence represented by SEQ ID NO: 1 or SEQ ID NO: 11; while also introducing a F3′H gene fragment derived from a lily and comprising a nucleotide sequence encoding a peptide having flavonoid 3′-hydroxylase activity, such as a nucleotide sequence represented by SEQ ID NO: 3 or SEQ ID NO: 16; and inhibiting the expression of endogenous F3′H expression, which acts on cyanidin synthesis in lily petals, while the F3′5′H gene that has been introduced acts to cause the synthesis of delphinidin.

摘要:
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.

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.
摘要:
There is provided a gene coding for the amino acid sequence listed as SEQ ID NO: 2 or SEQ ID NO: 70, for example. Co-expression of the 4′CGT gene and AS gene in a plant lacking natural aurone synthesis ability is carried out to successfully accumulate aurones and alter the flower color to have a yellow tint. In addition to the expression of both genes, the flavonoid pigment synthesis pathway of the host plant itself is inhibited to obtain flowers with a more defined yellow color.
