Abstract

Cyanide (CN) and dinitrophenol (DNP) rapidly depolarize the cells of oat coleoptiles (Avena sativa L., cultivar Victory) and of pea epicotyls (Pisum sativum L., cultivar Alaska); the effect is reversible. This indicates that electrogenesis is metabolic in origin, and, since active transport is blocked in the presence of CN and DNP, perhaps caused by interference with ATP synthesis, that development of cell potential may be associated with active ion transport. Additional evidence for an electrogenic pump is as follows. (1) Cell electropotentials are higher than can be accounted for by ionic diffusion. (2) Inhibition of potential, respiration, andactive ion transport is nearly maximal, but a potential of -40 to -80 mV remains. This is probably a passive diffusion potential since, under these conditions, a fairly close fit to the Goldman constant-field equation is found in oat coleoptile cells.
