Fig 7. Model validation and evaluation of the adaptive potential of plants to a range of different P_i concentrations.

Simulations (continuous line) and experimental data (experiment 3; dashed line) are shown for (A) shoot and (B) root growth, (C) root fraction, (D) shoot P_i concentration and (E) root P_i concentration and (F) total P_i per plant for plants grown at 6 different P_i concentrations (1, 10, 30, 100, 300, 1000 μM). The grey line in (a)-(c) represents the value at the beginning of the experiment. Error bars represent the standard deviations (N = 10).
