Abstract

Aluminum stress significantly stimulated K⁺ effux from barley roots that had been preloaded with K⁺ The stress also increased PP₁- and ATP-dependent H⁺ pump activities of tonoplast enriched membrane vesicles from the roots. Ca²⁺ ions reduced increases in K⁺ effux and both H⁺ pump activities under these conditions.
