Fig 6. Shared and unique gene clusters.

(A) The numbers of shared (present in at least one genome of each group) and unique (present in at least one genome of one group) gene clusters of B. breve and B. longum isolates from vaginal and gut microbiotas. Histograms below the Venn diagrams show the distribution of group-specific gene clusters among genomes and indicate that most group-specific gene clusters are found in only one genome. (B) Relationships of genomes based on presence/absence of gene clusters identified in the pangenomes for B. breve (3773 gene clusters) and B. longum (5609 gene clusters).
