Plant metabolic pathways stemming from L-phenylalanine and L-tyrosine. Colour represents the abundance difference between the three most divergent Medicago (M. sativa (n = 6), M. littoralis (n = 6), M. orbicularis (n = 6)) and Trifolium species (T.pratense (n = 5), T. nigrescens (n = 6), T. repens (n = 7)) for the discrimination LD1 score (log(fold change) in the mean % TIC of the m/z bin putatively associated with the compound). The pathway is based on the M. truncatula pathway in the KEGG database (www.genome.jp/kegg/pathway.html). Significance was tested by comparing the difference in the combined log %TIC between the Medicago and Trifolium groups using a linear regression model (using lm() function in R). Compounds underlined are those with putative m/z bins identified in RF models for both discrimination and overall acceptance.
