FIGURE 4

Rescue of the Al-sensitive phenotype of als1 by atr mutation. (A,B) Seedlings of WT, atr, als1, and als1atr were grown on a soaked gel medium containing 0, 0.5, 0.75, or 1 mM Al for 7 days. Data are means ± SD (n = 10–15). Means with different letters are significantly different (P < 0.05, Tukey’s test). Scale bar = 1 cm. (C) Rescue of QC differentiation of als1 by atr mutation. Seedlings of WT, atr, als1, and als1atr harboring QC46 (QC-specific marker) were grown on a soaked gel medium containing 0 or 1.5 mM Al for 7 days and the roots were stained with GUS staining solution and observed under a microscope. Scale bar = 50 μm.
