Supplementary Figure 8: Pan-genome fitting curves of the 38 clusters.
From: 1,520 reference genomes from cultivated human gut bacteria enable functional microbiome analyses

The pan-genome fitting curves of 38 representative clusters, from Firmicutes (orange), Bacteroidetes (blue), Actinobacteria (violet), Proteobacteria (green), and Fusobacteria (grey). The pan-genome size is accumulated from all combinations of strains contained in each cluster.
