A, Dendogram obtained following HCA of the metabolic profiles of the analyzed environmentally modified systems. Wherever possible, individual branches are grouped in brackets for ease of reading. B, PCA of the metabolite profiles of the analyzed environmentally modified systems. Samples representing wild-type tissue incubated in various concentrations of Glc (red circle), Fru (blue circle), Suc (yellow circle), and mannitol (green circle) are marked as described for ease of comparison. PCA vectors 1 and 2 were chosen for best visualization of differences between experimental treatments and include 62.4% of the information derived from metabolic variances.
