Phylogeny of RepA, TraI, and TrbG proteins encoded by pXF-RIV5.

<p>Neighbor-joining trees (1000 bootstrap replicates) presented are based on a multiple alignment of amino acid sequences. Bootstrap support values are shown for nodes with values >70%; nodes bearing ≤70% bootstrap support were collapsed to polytomies. Scale bar at lower left of each tree indicates a genetic distance of 0.1. Taxa names beginning with “p” are known to be encoded by plasmids, with plasmid designation preceding bacterial host nomenclature; replicon (plasmid versus chromosome) of other taxa is not specified. Taxa in red are encoded by strains of <i>Xylella fastidiosa</i>; multiple taxa assigned to a single branch are 100% identical. <i>X. fastidiosa</i> Ann-1 sequences identical to subspecies <i>multiplex</i> homologues are designated with an asterisk (Ann-1*) and may be derived from sequences contaminating the available Ann-1 strain genome sequence. Protein ID numbers are shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0052131#pone.0052131.s001" target="_blank">Table S1</a>.
