Comparison of Al and Cd accumulation pattern between WT and ral1 mutant. a Eriochrome Cyanine R staining of WT and ral1 mutant after 20 μM Al treatment for 24 h. Scale bar = 200 μm. b-d Comparison of total Al content (b), Al content in cell wall (c), and Al content in cell sap (d) in different root segments of WT and the mutant. Seedlings were exposed to a 0.5 mM CaCl2 solution containing 20 μM Al at pH 4.5 for 6 h. Root tips (0–1 cm) and basal roots (1–2 cm) were excised for Al determination. e, f Comparison of Cd content in cell wall (e) and Cd content in cell sap (f) in root tips of WT and the mutant. Seedlings were exposed to a 0.5 mM CaCl2 solution containing 5 μM Al at pH 4.5 for 6 h. Data are means ± SD (n = 3). Means with different letters are significantly different (P < 0.05, Tukey test)
