The superfamily of smallmonomeric GTPases originated in a common ancestor of eukaryotic multicellularorganisms and, since then, it has evolved independently in each lineage to cope with the environmentalchallenges imposed by their different life styles. Members of the small GTPase family function in thecontrol of vesicle trafficking, cytoskeleton rearrangements and signaling during crucial biologicalprocesses, such as cell growth and responses to environmental cues. In this review, we discuss theemerging roles of these small GTPases in the pathogenic and symbiotic interactions established by plantswith microorganisms present in their nearest environment, in whichmembrane trafficking is crucial alongthe different steps of the interaction, from recognition and signal transduction to nutrient exchange.
