Figure 5

Phylogenetic tree of IntI protein sequences. The tree is the majority-rule consensus tree generated by MrBayes. The tree was rooted using the Escherichia coli and Thiobacillus denitrificans XerCD protein sequences as outgroup. Bayesian posterior probabilities for each branch are displayed at each branching point. Inferred states for phenotypic traits derived from parsimony ancestral-state reconstruction analysis are displayed as follows. Integrase functionality: solid lines on tree branches represent inferred integrase functionality in that branch, and dotted lines indicate non-functionality. LexA regulation: at each taxon and branching point, small filled circles represent inferred presence of LexA regulation, and open circles indicate loss of LexA regulation. For clarity, the results of maximum likelihood reconstruction are not shown (see Additional file 6 and see Additional file 7 for these). The number of sequences mapping to each taxon in the reciprocal BLAST mapping analysis is shown between brackets after the taxon name. Stacked pie charts next to this number indicate the observed percentage of integrase functionality (upper pie) and LexA regulation (lower pie) in all the analyzed integrase sequences mapping to that specific taxon. The M letter followed by a subscript number (M X ) legend indicates mobile integron classes (1 to 5). Background colors delineate the main division into marine and soil/freshwater radiations and the XerCD outgroup.
