The pan-core genome of Collimonas strains. The venn diagrams illustrate the number of shared and unique genes based on clusters of orthologs. a Venn diagram showing numbers of species-specific genes commonly found in each genome of each species, (non-overlapping of each oval) and Collimonas core orthologous gene number (in the centre). The total number of protein coding genes within each genome is listed below the strain name. b Venn diagram showing numbers of unique orthologues genes in C. fungivorans strains. c Venn diagram showing numbers of unique orthologues genes in C. pratensis strains. d Venn diagram showing numbers of unique orthologues genes in C. arenae strains. e Core- and pan-genome as function of the number of genomes taken from the six Collimonas genomes in this study. The number of shared and strain specific gene clusters between strains depends on which combinations of strains (x-axis). Specific singleton gene clusters (blue bars) occur only in one strain, variable gene clusters (green bars) occur in more than one but not all strains and core gene clusters (red bars) occur in all strains of a given combination. Error bars represent the standard deviation in the core- (left error bar), variable- (middle error bar) and singleton- (right error bars) gene clusters
