Roles of the Arabidopsis G protein γ subunit AGG3 and its rice homologs GS3 and DEP1 in seed and organ size control.

The size of seeds and organs is coordinately determined by cell proliferation and cell expansion, but the mechanisms that set final seed and organ size are largely unknown in plants. In a recent study, we have demonstrated that the plant specific G protein γ subunit (AGG3) promotes seed and organ gr... View More
