a, b Root growth under control and Al (1 mM) treatments (a), and their relative quantification (b) (n = 17–21). 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). almt1 was used as a positive control. c–e Al content in 1 cm root tips (c), root sap (d) and root cell walls (e) under Al (25 µM) treatment (n = 9 in c, n = 8 in d, e). f Expression of ALMT1 in roots under control and Al (25 µM) treatments (n = 3). g Malate secretion from roots under control and Al (50 µM) treatments (n = 4). h Venn diagram showing the overlap of differentially expressed genes (foldchange > 1.5) between WT vs alr1-1 and WT vs stop1 under Al treatment. i, j GFP-STOP1 fluorescence signals in roots (i) and their relative quantification under Al treatment (j) (n = 20). Bars = 1 cm (a), 100 µm (i). All data were analyzed by unpaired t-test (b–f, g, j), or two-way ANOVA (f) (ns non-significance, **P < 0.01, ***P < 0.001, ****P < 0.0001).
