Unique root exudate compounds were detected within each treatment A (control), B (mild), and C (severe) at T2 (after treatment) using GC–MS. In total, 19 identified and non-identified metabolites were observed in treatments A, B, and C at T2 only (not at T1 (before treatment)). Identified metabolites unique to each treatment are listed while unidentified compounds are not listed (e.g. two compounds for A were not listed because they were not identified). Treatment B shared 10 compounds (6 identified and listed) with treatments A and C. Venn diagram of all (identified and unidentified) GC–MS metabolites found at T2 (including compounds from T1) are presented in Fig. S9.
