List of annotated, putatively identified secondary metabolites produced in response to host and nonhost interactions of P. syringae pathovars on oat leaf tissues.

Metabolites were identified according to MSI level 2 guidelines where the accurate mass, fragmentation data, database entries and published literature were used for annotation. These discriminatory metabolites were derived from OPLS-DA S-plots with rigorous statistical validation. VIP scores for all the reported metabolites were > 1.0. Presence or absence as discriminatory metabolites are shown for each treatment.
