Chemical similarity enrichment analysis (ChemRICH diagrams) of the metabolites found in plants under Fe deficiency (A), S deficiency (B) and dual deficiency (C), as obtained by UHPLC/QTOF-MS and GC-MS. Color is according to proportion of increased or decreased compounds (red = increased, blue = decreased, pink = mixed) within each cluster. A. Acids: amino acids; Ac., Carb.: Acids, Carbocyclic; An.: anisoles; BA.: Benzyl Alcohols; Ben. Derivs: benzene derivatives; Benz.: benzoates; Benzal.: benzaldehydes; But.: butyrates; C.-A. Acids: Amino AcidsCyclic; Caf. Acids: caffeic acids; Carot.: carotenoids; Cinn.: cinnamates; Coum. Acids: coumaric acids; Coum.: coumarines; DiCA.: dicarboxylic acids; Flav.: flavonoids; Flavo.: Flavones; Gly.: glycols; Hydroben.: hydroxybenzoates; Isoflav.: Isoflavone; Ket.: Ketones; PAH.: Polycyclic Aromatic Hydrocarbons; Phen.: phenols; Phenylac.: phenylacetates; SA.: Sugar Alcohols; Sat. FA.: saturated fatty acids.
