Figure 3

Magnitude and pattern of variation in biomarker metabolite concentrations in samples ranging in development. Four of the tissue samples representing a developmental range are profiled with respect to biomarker metabolite variation. The samples progress in height at mid-section of the sampled tissue and in days post-emergence, thus they represent a cross-section of the larger set of tissue samples. The biomarker metabolites are listed along the horizontal axis, and each dot plot shows the Z-scores for the biomarker metabolite concentration. The metabolites vary a lot in absolute concentration, so the Z-score is used to equalize the overall variation in concentration of the metabolites during the study. Thus the figure shows the pattern and magnitude of the variation among the presented tissues, but also the amount of this variation relative to that of the metabolite concentration for the whole study. For example, oxalic acid and glutamate both have a fairly wide range of Z-scores for these samples, although the pattern of variation is opposite.
