Abstract

The Rho family of GTPases are in higher eukaryotes divided into 3 major subfamilies; the Rho, Rac and Cdc42 proteins. In plants, however, the Rho family is restricted to one large family of Rac-like proteins. From work with mammalian phagocytes the Rac proteins are known to activate a multicomponent NADPH-dependent oxidase which results in accumulation of H2O2, a process termed oxidative burst. In plants a similar oxidative burst is observed and plays an important role in its defence against pathogen infections, suggesting a similar role for the plant Rac-like proteins. The Rho family of GTPases proteins are also involved in control of cell morphology, and are also thought to mediate signals from cell membrane receptors.
