Connectivity in metabolism in different growth regimes. In a given growth regime, each metabolite diel time series was regressed against every other metabolite diel time series. The results are presented as a heat map with Pearson correlation coefficients (R) indicated by the shading: red, positive correlation; blue, negative correlation. The colour scale is logarithmic and was chosen such that the majority of non-significant correlations (P<0.05) were not assigned any colour. Metabolites are grouped by pathway indicated by the coloured bars at the side of the heat maps. Expanded displays with information on individual metabolites are provided in Supplementary Fig. S6.
