From: Isolation and Characterization of an Aluminum-resistant Mutant in Rice
Sensitivity to other metals. Seedlings of WT and ral1 mutant were exposed for a 0.5 mM CaCl2 solution (pH 4.5) containing 0, 20 μM Al, 5 μM Cd, 5 μM La for 48 h. Data are means ± SD (n = 8). Relative root elongation (RRE) was used to evaluate their sensitivity to Al. Means with different letters are significantly different (P < 0.05, Tukey test)
