Fig. 3From: Tracing the phylogenetic history of the Crl regulon through the Bacteria and Archaea genomesPhylogenetic tree of Crl. Phylogenetic tree based on Crl of E. coli and homologs in other organisms generated via maximum likelihood analysis, with 1000 replicates. Species with bootstrap values higher than 60% are displayed. The black triangles to the right of the branches indicate multiple species for those generaBack to article page
