Abstract excerpt
Oryza rufipogon is the ancestor of cultivated rice and harbors many elite genes; thus, this plant is an important germplasm for improving rice varieties. Grain size is an important factor in determining rice yield and quality. In this study, we identified a natural variation allele from the O. rufipogon inbred line Huaye3 (HY3), which is located on chromosome 3 and named it GRAIN SIZE and WEIGHT 3.2 (OsGSW3.2)....
