<p><i>E. coli</i> Lsr system LMNAST hits overlaid onto a bacterial phylogenetic distribution as developed in and adapted from <a href="http://www.ploscompbiol.org/article/info:doi/10.1371/journal.pcbi.1002637#pcbi.1002637-Daubin1" target="_blank">[27]</a>. Each leaf bears a representative member from a larger unseen collapsed branch. The larger, bolded leaves contain Lsr system homologs within the collapsed branch, whereas the grayed italicized leaves do not. Parenthesized numbers indicate the number of strains and species with Lsr system LMNAST hits contained within the collapsed branch.</p
