The effect of Al on activity of the V-ATPase,
F1F0-ATPase, and P-ATPase.
ATPase specific activity was measured in total microsomal membranes
prepared from 1-cm root tips of the Al-resistant cv PT741. Five-day-old
seedlings were treated with different concentrations of Al (0, 25 50,
75, 100, and 150 μm) for 48 h. Values are means
± se of three biological replicates and are representative
of three independent trials.
