Cloning of Rac and Rho-GDI from tobacco using an heterologous two-hybrid screen.

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.

A secondary mode of action of the herbicide lenacil: Modification of K+ permeability of Acer pseudoplatanus cells

Abstract The action of lenacil on plasmalemma permeability to K+, transmembrane electric potential difference (PD) calculated from the tetraphenylphosphonium distribution, proton extrusion and intracellular pH of Acer pseudoplatanus cells calculated from the 5,5-dimethyloxazolidine,4-dione distribution, was studied and compared with the action of fusicoccin (FC) and diethylstilbestrol (DES). The three compounds temporarily stimulated the rate of 86Rb+ uptake with a half-maximum effect at 5.0 μM for 3-cyclohexyl-6, 7-dihdro-1H-cyclopentapyrimidine-2,4(3H,5H)-dione (lenacil). Lenacil and FC had no action on transmembrane electric potential difference, whereas DES decreased it. Lenacil inhibit…
