Phylogeny of predicted AvrRxo1-like and Arc1-like proteins in plant pathogenic and environmental bacteria.

<p>Neighbor-Joining tree of aligned amino acid sequences from 12 AvrRxo1 homologs (<b>A</b>) and 16 Arc1 homologs (<b>B</b>). Sequence accessions and strains are listed in Tables <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0158856#pone.0158856.t001" target="_blank">1</a> and <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0158856#pone.0158856.t003" target="_blank">3</a>. The datasets consisted of 260 (<b>A</b>) and 74 (<b>B</b>) amino acids after gap elimination. Bootstrap percentages for 1000 replicates are shown next to branches. Units represent the number of amino acid substitutions per site.
