Effect of elevated Cu on H⁺-ATPase genes (AHA family).

Roots of Arabidopsis thaliana were supplied with different Cu levels in the nutrient solution for 72 h or 15 days (15d). Mean (+/– SEM) are shown (n = 3). Different letters in the same period are significantly different among the [Cu] (Tukey’s test, p < 0.05).
