One purpose of summarizing the present invention is to provide a method for making a flashlight in which a malonilo group adds glucose at position 7, uses a polynucleotide encoded protein, and its activity shifts the malonilo group to glucose position 6 at position 7. 7 glucose, and created a plant variety with an improved decor, preferably a bluer one than the existing variety, because it contains a flashlight as a replica, adding a set of maloni to the glucose in position 7. Using polynucleotide selected from the group,For example: (a) polynucleotide composed of SEQ ID No.1 base sequence； (b) A polynucleotide, mixed with polynucleotide under strict conditions, consisting of the base sequence of the No. 1 SEQ base sequence and encoding an active protein, transferring a group of maloni to glucose position 6 at 7-glucose position 7； (c) A polynucleotide that encodes a protein as an amino acid sequence of SEQ ID No.2； and (d) a polynucleotide that encodes a protein as an amino acid sequence in which one or more amino acids are removed,It was substituted, inserted and / or polymerized in the amino acid sequence of SEQ ID No.2, and a group of maloni was actively transferred to glucose position 6 of flavna 7-glucose position 7.RESUMEN Un objeto de la presente invención es proporcionar un método para producir una flavona en la que un grupo malonilo se agrega a una glucosa en la posición 7 utilizando un polinucleótido que codifica una proteína que tiene actividad que transfiere un grupo malonilo a la posición 6 de la glucosa en la posición 7 de la flavona 7-glucósido, y crea una variedad vegetal que tiene un color de flor modificado, y preferiblemente un color de flor que es más azul que el de las variedades existentes, al contener como copigmento una flavona en la que se ha agregado un grupo malonilo a la glucosa en la posición 7. Se utiliza un polinucleótido que se selecciona del grupo que consiste en, por ejemplo: (a) un polinucleótido compuesto por la secuencia de base
