Four amino acids were variable between the ‘active’ indica-type and ‘inactive’ japonica-type soluble starch synthase IIa (SSIIa) of rice plants; Glu-88 and Gly-604 in SSIIa of indica-cultivars IR36 and Kasalath were replaced by Asp-88 and Ser-604, respectively, in both japonica cultivars Nipponbare and Kinmaze SSIIa, whereas Val-737 and Leu-781 in indica SSIIa were replaced by Met-737 in cv. Nipponbare and Phe-781 in cv. Kinmaze SSIIa, respectively. The SSIIa gene fragments shuffling experiments revealed that Val-737 and Leu-781 are essential not only for the optimal SSIIa activity, but also for the capacity to synthesize indica-type amylopectin.
