The neighbor-joining phylogenetic tree of FcproPO isoforms and proPO homologues from other species.

<p>Sequence information was summarized in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0058627#pone.0058627.s002" target="_blank">Table S2</a>. Bootstrap analysis of 1000 replicates was carried out to determine the confidence of tree branch positions. And the numbers marked on the tree branches represent the bootstrap values.
