Abstract
The influence of K+ on the Na+ fluxes of barley root cells was investigated. A increased K+ concentration (K+ influx) results in a transient increase of the plasmalemma efflux of Na+ followed by a decrease, and in a decrease of the cytoplasmic content and the tonoplast influx of Na+. These results are consistent with a Na-K-pump at the plasmalemma.Keywords
