Fig. 4.

Discrimination of fluxes according to both inoculation and N supply. Principal component analysis (PCA) performed on unbounded fluxes >0.001 µmol g DW^–1 d^–1 (in absolute value). Data were cube-root-transformed and Pareto-normalized (mean-centred and divided by the root-square of standard deviation). (A) Score plot with one point for each simulated condition. Filled circles, mock-inoculated plants; open circles, Botrytis-inoculated plants. N supply is represented by colour: 0.5 mM NO₃^– in orange, 2 mM NO₃^– in yellow, 5 mM NO₃^– in light purple, and 20 mM NO₃^– in dark purple. The simulation days are not differentiated. (B) Loading plot with the names of the 15 reactions contributing most to principal component (PC) 1 and PC 2.
