The α subunit of a prototypical heterotrimeric GTP-binding protein (G protein), which is encoded by single gene ( GPA1 ) in Arabidopsis , modulator plant cell proliferation. gpa1 null mutants have reduced division aerial tissues throughout development. Inducible overexpression confers inducible ectopic division. synchronized BY-2 cells causes premature advance the nuclear cycle and appearance wall. Results from loss function expression activation indicate that this positive plants.
