Root growth in fluoride is impaired in mutants and restored by AtFEX. A, Seeds from FEX/fex plants, mutant plants (fex/fex), and rescued mutant plants (fex/fex (AtFEX)) were plated on no and low fluoride. The root lengths of 7-d seedlings were measured and then genotyped. B, Root lengths of plants overexpressing AtFEX (line 14 data are the first open box followed by line 31) were compared with those of FEX/FEX (WT) plants. In both panels, one-way ANOVA (Tukey: calculated P-values are **** and ** indicating <0.0001 and <0.01, respectively). Both graphs represent one biological replicate of three total replicates with N ≥ 10. Bars on box plots indicate min and max measurements and the horizontal line indicates the mean.
