Root exudation of malate (a) and citrate (b). Here, 6-day-old seedlings of WT, almt1, nip1;2 and almt1nip1;2 were treated in 20 ml of exudation buffers (pH 4.3) supplemented without (−) or with (+) 50 μM AlCl3 for 2 days before the concentrations of malate and citrate in the exudation buffer were determined. Data are means ± s.d. of three biological replicates. Letters represent groups with significant differences (P ≤ 0.05)
