Provided is a polynucleotide encoding a protein that exhibits activity for transferring a sugar to a hydroxyl group at position 7 of a flavone, particularly flavone 4'-glucoside, wherein the polynucleotide is selected from the group consisting of: (a) a polynucleotides comprising the base sequence of SEQ ID NO: 1 or SEQ ID NO: 5; (b) a polynucleotide that hybridizes, under stringent conditions, with a polynucleotide comprising the base sequence complementary to the base sequence of SEQ ID NO: 1 or SEQ ID NO: 5; (c) a polynucleotide encoding a protein comprising the amino acid sequence of SEQ ID NO: 2 or SEQ ID NO: 6; (d) a polynucleotide encoding a protein comprising an amino acid sequence in which one or more amino acids have been deleted, substituted, inserted, and/or added in the amino acid sequence of SEQ ID NO: 2 or SEQ ID NO: 6.

Glycosyltransferase gene and use thereof

Provided is a polynucleotide encoding a protein having activity that transfers a sugar to the hydroxyl group at the 4'-position of a flavone, wherein the polynucleotide is selected from the group consisting of: (a) a polynucleotide composed of the base sequence of SEQ ID NO: 1; (b) a polynucleotide that hybridizes under stringent conditions with a polynucleotide composed of a base sequence complementary to the base sequence of SEQ ID NO: 1; (c) a polynucleotide encoding a protein composed of the amino acid sequence of SEQ ID NO: 2; and, (d) a polynucleotide encoding a protein composed of an amino acid sequence in which one or a plurality of amino acids have been deleted, substituted, inserted and/or added in the amino acid sequence of SEQ ID NO:2.

Provided is a polynucleotide encoding a protein having an activity to transfer a sugar to the hydroxy groups at the 4'- and 7-positions of a flavone. The polynucleotide is selected from the group consisting of: (a) a polynucleotide which comprises a base sequence represented by SEQ ID NO: 1, 3, or 12; (b) a polynucleotide which hybridizes to a polynucleotide comprising a base sequence complementary to a base sequence represented by SEQ ID NO: 1, 3, or 12 under high stringency conditions, and encodes a protein having an activity to transfer a sugar to the hydroxy groups at the 4&#x2032;- and 7-positions of a flavone; (c) a polynucleotide which encodes a protein comprising an amino acid sequence represented by SEQ ID NO: 2, 4, or 13; (d) a polynucleotide which encodes a protein comprising an amino acid sequence in which one or more amino acids have been deleted, substituted, inserted, and/or added in an amino acid sequence represented by SEQ ID NO: 2, 4, or 13 and having an activity to transfer a sugar to the hydroxy groups at the 4&#x2032;- and 7-positions of a flavone; etc.

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.

Plants with improved morphogenesis and method of constructing the same

The present invention provides arachidonic acid-containing plants and soybeans, and a method of use thereof. The arachidonic acid-containing plant is produced by a process that includes an arachidonic acid producing step in which fatty acid synthetase genes associated with the biosynthesis of arachidonic acid are introduced into a plant to produce arachidonic acid. Thus, plants or soybeans containing arachidonic acid can easily be obtained. Therefore, it is possible to obtain a large amount of arachidonic acid at low cost.
