Ionomic profile of basil plants. (A) Relative abundance of macronutrients in both cv. Genovese and cv. Red Rubin plants grown in control hydroponic solution, in a NO₃^–- or in a SO₄^2–-overfertilized nutrient solution, either non-inoculated or inoculated with A. brasilense. (B) Relative abundance of micronutrients in both cv. Genovese and cv. Red Rubin plants grown in control hydroponic solution, in a NO₃^–- or in a SO₄²-overfertilized nutrient solution, either non-inoculated or inoculated with A. brasilense. Relative abundance has been calculated by normalizing the concentration of each single element in all the different treatments considered to the concentration of the fame element in the non-inoculated control sample. Concentration data and statistical analyses are reported in Supplementary Tables 6,7.
