Research Abstract

The size of starch grains differs depending on the plant species and is one of the most important factors for industrial applications of starch. However, the molecular machinery that regulates the size of SGs is unknown. We are studying a novel rice mutant called ssg4 (substandard starch grain 4) that develops enlarged SGs in the endosperm. We identified the SSG4 gene by map-based cloning and performed various characterization of SSG4 gene.
