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&#x2032;-hydroxylase.

Method for producing rose with altered petal colors

A method of acylating the 3' position of anthocyanin using an enzyme that transfers an aromatic acyl group to a sugar at the 3&#x2032; position of anthocyanin or a gene encoding the enzyme.

Stabilization and blueing of anthocyanin pigments using gene encoding aromatic acyltransferase capable of transferring an aromatic acyl group to the 3'-position of anthocyanin

The present invention provides an enzyme that catalyzes the reaction producing piperitol from pinoresinol, and a reaction producing sesamin from piperitol. The invention also provides a gene that encodes such enzyme. Further, the invention provides a vector and transformant including a gene encoding the enzyme, and a producing method of the protein using the transformant.

Gene encoding an enzyme for catalyzing biosynthesis of lignan, and use thereof

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.

Method for producing yellow flower by controlling flavonoid synthetic pathway

The present invention provides a protein having aurone synthase activity involved in the color of flowers such as snapdragons, a gene that encodes it, cDNA in particular, and its applications. This gene can give yellow color to the flowers of plants by introducing into plants deficient in chalcone isomerase and so forth and expressing.

Gene encoding a protein having aurone synthesis activity

A flavone synthase that synthesizes flavones from flavanones, vectors containing DNAs encoding said flavone synthases, and plants expressing same are disclosed. Methods of producing the protein which synthesizes flavones from flavanones, methods of altering the composition of flavonoids or the amount of flavonoids in a plant, methods of altering flower color and plant photosensitivity, and methods of controlling interactions between plants expressing the protein and microorganisms are also disclosed.

Flavone synthases, methods of using flavone synthases, and plants expressing flavone synthases

The present invention provides a gene that codes for a protein, wherein the protein is an anthocyanin 5-O-glucosyltransferase, which is an enzyme that transfers a glycoside to the 5 position of a flavonoid. The disclosed anthocyanin 5-O-glucosyltransferases were isolated from, and. Also disclosed are genes that code for a protein having a modified amino acid sequence relative to the above amino acid sequence and having activity that transfers a glycoside to the 5 position of a flavonoid, and a process for producing the above protein using said gene. This gene can be used to artificially alter the color of plants.

Proteins having a flavonoid 5-O-glycosyltransferase activity (5GT)

A [DNA encoding a] flavone synthase that synthesizes flavones from flavanones, vectors containing said DNAs encoding said flavone synthases, and plants expressing same are disclosed.
