Figure 2. Comparison of hierarchical clustering and phylogenetic tree of a selected set of L. rhamnosus strains.

Both hierarchical clustering (panel A) and phylogenetic tree (panel B) were performed on all L. rhamnosus strains, excluding isolates from unspecified or clinical origins. Coloured strings connecting the same strains of both trees aims at highlighting the degree of similarities between both tree methods [78], [79].
