Table S1 Primers used in this study.
Table S2 Identified metabolites whose concentration showed strongly significant differences between elevated O3 and control treatment in wheat (fold change≥2 and ≤ 0.5, P <0.05).
Table S3 Identified metabolites whose concentration showed strongly significant differences between O3 stresses and control in rice (fold change≥2 and ≤ 0.5,P <0.05).
Table S4 Identified metabolites whose concentration showed strongly significant differences between O3 stresses and control in soybean (fold change≥2 and ≤ 0.5,P <0.05).
Fig. S1 Hierarchical clustering analysis (HCA) of differentially accumulated metabolites in wheat, rice, and soybean under elevated O3. Hierarchical trees drawn were based on detected metabolites in leaves of wheat, rice and soybean in charcoal filtered air (CF) condition and elevated [O3] (EO) treatment. Columns represent different crops at different conditions and rows indicate different metabolites.
