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.

Abstract: 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.

Abstract: Disclosed is a method for determining whether or not a wild rose of interest is crossed with a cultivated rose. The method comprises the steps of: examining whether or not a KSN gene containing a transposon (an indicator) is contained in the rose of interest; and determining that the rose of interest is crossed with a cultivated rose when the individual has the transposon-containing KSN gene.

Abstract: The present invention relates generally to the field of plant molecular biology and agents useful in the manipulation of plant physiological or biochemical properties. More particularly, the present invention provides genetic and proteinaceous agents capable of modulating or altering the level of acidity or alkalinity in a cell, group of cells, organelle, part or reproductive portion of a plant. Genetically altered plants, plant parts, progeny, subsequent generations and reproductive material including flowers or flowering parts having cells exhibiting an altered cellular pH compared to a non-genetically altered plant are also provided.

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: The invention relates to plants and their progeny with improved morphogenesis in a variety of organs; to a method for producing the plants; and to a method for producing calli.

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.
