In this study, we isolated a mutant, which exhibits altered grain shape and identified the mutated gene, gs9-1. Our study reveals that gs9-1 is a semi-dominant gene that carries a two-amino acid mutation. gs9-1 is allelic to the BC12/GDD1/MTD1 gene involved in GA biosynthesis. These results demonstrate the efficiency and convenience of cloning genes from the whole-genome sequenced Kitaake mutant population to advance investigations into genes controlling key agronomic traits in rice.
