Expression in the root apices was estimated by qRT–PCR using the GAPDH gene as an internal reference. Data are the mean and standard error of three biological replicates. Malate efflux was measured from excised root apices in the presence of 50 µm AlCl3. Data show the mean and standard error (n = 4).
