The neighbor-joining phylogenetic tree of FcALF isoforms and ALF homologues from other species.

<p>Sequence information were summarized in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0058627#pone.0058627.s002" target="_blank">Table S2</a>. Signal peptide of each ALF was deleted when analyzed. 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.
