DNA MOLECULE ENCODING ENZYME PARTICIPATING IN STARCH SYNTHESIS, AND VECTOR, BACTERIUM, TRANSGENIC PLANT CELL AND TRANSGENIC PLANT CONTAINING THE DNA MOLECULE
PROBLEM TO BE SOLVED: To provide a DNA of a soluble starch synthase, a transgenic plant cell and a plant body. SOLUTION: The enzyme participating in the starch synthesis of plant is composed of two different isotypes of a soluble starch synthase and a starch granule-bound starch synthase. The invention provides a DNA molecule encoding an enzyme participating in starch synthesis, and a vector, a bacterium, a transgenic plant cell and a transgenic plant containing the DNA molecule. It further provides starch separable from a plant having increased or decreased activity of the protein. COPYRIGHT: (C)2006,JPO&NCIPI
