OPLS-DA applied to NMR and MS data obtained by the analysis of olive leaves (Xf+: samples from X. fastidiosa inoculated plants; Xf−: samples from X. fastidiosa non-inoculated plants). (a) OPLS-DA applied to NMR data: t(1)/tO(1) score plot relating to P1/O1; (b) OPLS-DA applied to MS data: t(1)/tO(1) score plot relating to P1/O1.
