International audience; To examine whether molecular similarities exist between the animal and plant Rho GTPase signaling pathways, we have developed a heterologous two-hybrid screening method. By this technique, we have cloned a cDNA encoding a tobacco Rac-like protein able to interact with a mammalian Rho-GDI. In a second screen this tobacco Rac was used as a bait and a tobacco homologue of Rho-GDI was identified. These results show that some components of the animal and plant Rac signaling pathways are similar enough to allow their interaction in an heterologous approach. Moreover these data suggest a similar regulation of Rho GTPases in animals and plants.
