Abstract

Levels of abscisic acid (ABA) in barley roots increased upon treatment with AlCl3. Treatment with AlCl3 or ABA increased both ATP-dependent and PPi-dependent H+-pumping activities in tonoplast-enriched membrane vesicles. Increase in the H+-pumping activities caused by aluminum stress could result from increased levels of ABA.
