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.
