| Research Abstract |
At least four classes of enzymes responsible for starch biosynthesis in higher plants have been known. Rice mutants deficient in specific isozymes of each class accumulate unique starch in the endosperm. Starch synthase (SS), which elongate linear glucosyl-chains of starch, have the largest numbers of isozymes, and each SS isozyme has been suggested to play distinct roles. In this study, double mutants of SS and other classes and transgenic lines were produced. Their starches show unique physicochemical properties that are useful for production of food, foodstuffs, and other materials in industrial scale.
