Cell polarity control is inherently a complex process based on the feedback loops where it is difficult to distinguish cause – effect relationships and identify “ master regulators. ” However, small GTPases from the Rac/Rho family are certainly an important part of polar growth core regulatory circuit/network also in plants. ROPs (Rac/Rho of plant) involvement in root hair polar tip-growth is best documented by the loss of polarity in plants overexpressing specific ROP GTPases, loss of polarized cell expansion in root hairs of RopGDI mutant and root hair tip localization of ROP-GFP fusions. Rho/Rac GTPases switch directs cell growth via a plethora of regulatory and effector proteins known from Opisthokonts, and only recently some of them have been identified also in plant cells.
