Principal component analysis (PCA) and hierarchical cluster analysis (HiCA) models of UHPLC-MS ESI(–) data of extracts from tomato leaves. The PCA score plots illustrate the group clustering after treatment with (A) Flg22 peptide and (C) the FlgII-28 peptide, and incubated for 16 h (blue), 24 h (purple) and 32 h (yellow) respectively. A MgSO4 control (grey) was included in each elicitor treatment. The hierarchical cluster dendrograms are derived from the PCA model data and outline the overall hierarchical structure of (B) Flg22 and (D) FlgII-28 treatment over the above-mentioned incubation times
