Overall flux distribution. Flux maps of symptomless stems of mock-inoculated tomato plants grown under 5 mM NO₃^– 6 d post-inoculation. The open circles represent metabolites, and the sizes of the arrows represent the metabolic fluxes expressed in µmol g DW^–1 d^–1. The dotted lines represent metabolic fluxes with an absolute value of <0.001 µmol g DW^–1 d^–1. Each colour indicates a pathway. The complete network with all the names of the metabolites and reactions is presented in Supplementary Fig. S1.
