Research Abstract	To elucidate the molecular mechanisms of sugar translocation and metabolism, five lines of rice mutant that accumulate high levels of leaf starch were characterized. In one mutant line named LSE1, disruption of a gene for glucan water dikinase was revealed to be a responsible gene. Gene mapping and physiological characterization were done also in other four mutant lines.
