Abstract excerpt

Grain shape is a critical factor that directly influences rice yield and quality, however, the molecular mechanisms underlying the regulation of grain shape development remains elusive. In this study, we characterized an oval-shaped grain mutant, osg, from the rice radiation mutagenesis mutant library via 60Co-γ ray irradiation. Compared to ZH11, the osg mutant exhibited decreased grain length and thousand-grain...
