Formation of three geography-related populations and evolution driven mainly by admixture within each population. A B. longum population structure revealed by FineSTRUCTURE analysis. The color of each cell in the co-ancestry matrix represents the anticipated number of DNA chunks imported from a donor strain (column) to a recipient strain (row). The color bar near the tree represents the geographical locations where the strains were sampled. B Genomic compositions of B. longum strains inferred by chromosome painting. Each vertical bar represents one strain, and the bars are sorted by geographical location. The color of each bar represents the contribution by each of the three populations to the core genome of that strain. The color bar at the bottom indicates the sampling locations. Two hundred and ninety-five representative strains retained after FineSTRUCTURE runs were used for this part of analyses
