| Outline of Final Research Achievements |
Heterotrimeric G-proteins are consisted of α, β, and γ subunits, regulating important agronomic traits including grain size, grain number, and dwarfism in rice.
Of five γ subunits in rice, one is the GS3 gene, which promotes grain size, and the another one is the DEP1 gene, which promotes grain number and defines semi-dwarfism. α subunit regulates grain size, grain number and plant height.
In this study, we performed genetic analysis using mutants and transgenic plants of heterotrimeric G-protein genes to clarify its mechanism of signal transduction.
