Putative Ca2+channels of plasma membrane vesicles are not involved in the tolerance mechanism of aluminum in aluminum tolerant wheat (Triticum aestivumL.) cultivar

Abstract
We compared the effect of aluminum on the calcium (45Ca2+) influx through putative calcium channels of plasma membrane vesicles isolated from two wheat (Triticum aestivum L.) cultivars differing in Al sensitivity. Bepridil, a calcium channel blocker, and aluminum suppressed the influx in both cultivars. However, no differences were observed in the effects of these treatments between the two cultivars.
