Abstract

After 2 months from the infestation of tomato plants with the root-knot nematode (RKN) Meloidogyne incognita,we performed a gas chromatography-mass spectrometry untargeted fingerprint analysis for the identification of characteristicmetabolites and biomarkers. Principal component analysis, and orthogonal projections to latent structures discriminant analysissuggested dramatic local changes of the plant metabolome. In the case of tomato leaves, ?-alanine, phenylalanine, and melibiosewere induced in response to RKN stimuli, while ribose, glycerol, myristic acid, and palmitic acid were reduced. For tomato stems,upregulated metabolites were ribose, sucrose, fructose, and glucose, while fumaric acid and glycine were downregulated. Thevariation in molecular strategies to the infestation of RKNs may play an important role in how Solanum lycopersicum and otherplants adapt to nematode parasitic stress
