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.
