Abstract: 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.

Abstract: 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.

Abstract: 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 Perilla fruescens, Verbena hybrida, Torenia hybrida, and Petunia hybrida. 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.
