a Quantification of the binding affinity of ALR1CD, mutated ALR1CD (ALR1CD4C-A) and BAK1CD for Al ions by MST (n = 4 for ALR1CD, n = 3 for ALR1CD4C-A and BAK1CD). b Quantification of the binding affinity of ALR1CD for metal ions other than Al by MST. c, d Root growth under control and Al treatment (c), and their relative quantification (d) (n = 20). The average length of each genotype was set to 100%, and the relative root length was expressed as a percentage (root length with Al treatment/root length without Al × 100). e Phosphorylation of RbohDN by ALR1CD or ALR1CD4C-A in response to Al. f, g GFP-STOP1 fluorescence signals in roots (f) and their relative quantification under Al treatment (g) (n = 20). Bars = 1 cm (c), 100 µm (f). All data were analyzed by unpaired t-test (d, g) (ns non-significance, ****P < 0.0001).
