Contribution of increased mutagenesis to the evolution of pollutants-degrading indigenous bacteria - Fig 3

<p><b>The phylogenetic trees of RulA (A) and RulB (B) protein sequences. Underlining indicates the genes of proteins which are located on plasmids.</b> Sequences derived from <i>P</i>. <i>fluorescens</i> strains PC20 and PC24 are shown in boldface. Sequences were aligned with ClustalX2 and further visualised with TreeViewX. Numbers at branch nodes indicate bootstrapping values for 1000 bootstrap replicates. Values under 500 were removed. The identifiers of the aligned sequences are presented in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0182484#pone.0182484.s015" target="_blank">S7 Table</a>.
