Metabolic differences induced by T. viridana in T- and S-oaks, as response of phenotypes, leaf age dependences and systemic responses. Heat maps of KEGG annotated significantly discriminant masses originated by partial least square regression (PLSR) analysis of metabolomic data showing (A) phenotypic/genotypic differences between T- and S-oaks, (B) leaf age developmental changes between fed plants (32 h) at early developmental leaf stage (2–4 weeks after budbreak; 'Y’) and 4 weeks later (6–8 weeks after budbreak 'O’), (C) differences between damaged leaf (d) and intact leaves (I) of fed plants. Metabolites are grouped into the main metabolism pathways according to KEGG [31]. Significance was tested with Martens’ test [83].
