Maximum likelihood tree of Xanthomonas pth genes. The sequences used to build the tree had their tandem repeat portions masked before alignment. The root position was obtained from a preliminary tree that included as an outgroup a Ralstonia solanacearum pth gene [GenBank: CAD15517.1]. Full information about the pth gene sequences used is given in additional file 6 (Table S6). The numbers on branches represent bootstrap support (from 100 bootstrap runs). The bootstrap values obtained for the clade indicated by the asterisk * are given in additional file 7 (Fig. S7). Bar, number of amino acid substitutions per site.
