Compatible and Incompatible Rhizobia Alter Membrane Potentials of Soybean Root Cells

Tibor Érsek1, Anton Novacky and Steven G. Pueppke

Department of Plant Pathology, University of Missouri, Columbia, Missouri 65211

Inoculation with Rhizobium japonicum or R. meliloti reduced the electrical transmembrane potential (Em) of soybean (Glycine max [L.] Merr.) root cells within 1 day. The response could be attributed to altered diffusion potential (ED). Em values return to control levels by the second day after inoculation, but again were reduced in R. meliloti-inoculated tissue on the seventh day. Increased concentrations of sodium phosphate in the perfusion solution magnified the effects of inoculation on Em. Neither heat-killed rhizobia nor living cells of Pseudomonas fluorescens elicited the response. The Em and ED of nodule cells were nearly 20% lower than corresponding values from adjacent cortical cells of the root.
