General Information

General Information Comment Organism
malfunction mutations in the starch synthase IIIa gene, in combination with a highly expressed Waxy gene, lead to a high level of resistant starch Oryza sativa
physiological function grain qualities and physicochemical properties of starch are determined by SSIIIa. Biosynthesis of resistant starch is regulated by SSIIIa. Mutation of SSIIIa gene results in elevation of resistant starch Oryza sativa
