  1. When the response ratio (level in a given treatment divided by the level in the +Fe treatment) was lower than 1 the inverse was taken and the sign changed. Values indicated in bold represent a t-test significance of p < 0.05. The last column shows A. thaliana KEGG pathway numbers where the metabolite is predicted to be involved; all KEGG pathway numbers are hyper-linked to the corresponding KEGG website. To reach one specific pathway in KEGG type in your web browser: "http://www.genome.jp/kegg-bin/show_pathway?ath0XXXX" being XXXX the pathway number.
