Abstract excerpt

The present study compared the starch-related phenotypes in rice endosperm between two water-soluble glucan (WSG)-accumulating mutants, sugary-1 (EM653) and sugary-2 (EM324). Although both mutants contained iodine-staining starch regions and iodine-unstaining WSG regions, the structural features of WSG and amylopectin and internal structures of starch granules differed between lines. In EM653 endosperm,...
