Figure 2

Pan-virome analysis of the P335 and 936 phage species. 2A) Heatmap showing the hierarchical clustering analysis conducted on the P335 and 936 data sets. The separation achieved between the two species is indicated by a vertical red line, while the 936 common genes (core genome) area is indicated by a horizontal green line. B & C) Accumulated number of P335 (b) or 936 (c) pan-virome genes, respectively, plotted against the number of P335 (b) or 936-species (c) phage genomes added. The deduced mathematical function is also indicated.
