| Title | <i>OsGGC2</i>, Ggamma Subunit of Heterotrimeric G Protein, Regulates plant height by Functionally Overlapping with <i>DEP1</i> in Rice. | |
|
Abstract: Plant heterotrimeric G proteins have been shown to regulate the size of various organs. There are three types of Ggamma subunits in plants: type A, consisting of a canonical Ggamma domain; type B, possessing a plant-specific domain at the N-terminus of the Ggamma domain; and type C, possessing a plant-specific domain at the C-terminal of the Ggamma domain. There is one type A, one type B, and three type C of the five gamma-subunits in the rice genome. In type C Ggamma subunits, <i>GS3</i>, which controls grain size; <i>DEP1</i>, which controls plant height and panicle branching; and their homolog <i>OsGGC2</i>, which affects grain size, have been reported; however, the function of each gene, their interactions, and molecular mechanisms for the control of plant height have not yet been clarified. In this study, we generated loss-of-function mutants of <i>DEP1</i> and <i>OsGGC2</i>, which have high homology and similar expression, and investigated their phenotypes. Since both <i>DEP1</i> and <i>OsGGC2</i> mutants were dwarfed and the double mutants showed a synergistic phenotype, we concluded that both <i>DEP1</i> and <i>OsGGC2</i> are positive regulators of plant height and that their functions are redundant. |
