Maximum-likelihood phylograms depicting evolutionary relationships for two genes in module 1 (p41 and p45) and two genes in module 4 (p19 and p24) of APSEs, other phages and other phage elements from bacteria in the order Enterobacteriales. Numbers at nodes indicate percent of 1000 bootstrap replicates that recovered the same node. For each gene, tip labels indicate the APSE haplotype, sequenced phage, or bacterium containing a prophage element in which the ortholog resided. Scale bars indicates nucleotide substitutions per site. Tick marks indicate branches lengths at the root have been reduced
