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.

为了阐明糖运输和代谢的分子机制，对5个积累高水平叶片淀粉的水稻突变体进行了鉴定。在一个名为LSE1的突变株系中，葡聚糖水二激酶基因的破坏被发现是一个负责的基因。对其他4个突变株系也进行了基因定位和生理特性研究。
