From: Environmental variability and modularity of bacterial metabolic networks
Relation between environmental variability and a. Mean fractional number of transcription factors out of the total number of genes in the genome. b. Mean metabolic network size (giant component). Error bars represent standard errors. Abbreviation: O-Obligate, S-Specialized, AQ-Aquatic, F-Facultative, M-Multiple, T-Terrestrial. Groups ordered along x-axis according to their predicted level of variability.
