Abstract

The research on Rho GTPases in plants is gaining momentum with passing years. Analogous to animal Rho-related small GTPases, crucial role of plant ROP GTPases in cell polarity and morphogenesis has been established. Several evidences have been put forward to show that they also serve as molecular switch in plant signaling pathways. Besides similarities at the regulation level in Rho-related GTPases in plant and non-plant organisms stimulating deviations have also been explored. These deviations at the regulatory and functional levels are important to understand fundamental signal transduction mechanism and thus needs further investigation. In order to understand the evolution and survival of diverse signaling mechanisms, biochemical and kinetic analyses of ROPs and their regulators can provide valuable information. The large ROP gene family performs diverse physiological functions in plants and due to that identification of its specific signaling pathway appears to be challenging. To answer these questions efforts need to be concentrated towards acquiring knowledge about upstream and downstream signaling events affecting ROP functioning at the molecular level.
