Regulation of Membrane Trafficking, Cytoskeleton Dynamics, and Cell Polarity by ROP/RAC GTPases

Abstract

Rho of plants (ROP) proteins, also known as RAC proteins, are Rho-related GTPases that function as molecular switches in a multitude of signaling cascades involved in the regulation of the actin and microtubule cytoskeleton, of vesicle trafficking, and of plant responses to hormones, stresses, or
