Cluster analysis of the four Shewanella models based on different criteria. In silico Shewanella cluster analysis including a dendrogram and a heat map for i MR1_799, i MR4_812, i W3181_789, and i OS217_672 based on metabolic genes (A), and predicted growth phenotypes (B). Each leaf spaced evenly along the horizontal axis of the dendrogram and each column in the heat map represents each Shewanella model. The vertical axis of the dendrogram indicates a distance measure. The height of each branch represents the distance between the two clusters. The rows in the heat map represent different growth conditions (i.e., carbon source and electron acceptor). The heat maps indicate whether the metabolic gene is present in each strain (panel A) and whether the strain is predicted to grow in the given growth condition (panel B). Note that genes that are present in all four strains and growth conditions where all four strains had the same predictions (growth or no growth) were omitted from this figure for clarity. This omission does not affect the clustering results.
