Phylogenetic tree constructed by maximum likelihood method based on the amino acid sequences of c-type lysozymes from invertebrate animals.

<p>Numbers at the forks indicate the bootstrap values (in %) out of 100 replicates. The sequences of c-type lysozymes from vertebrate animals (<i>Scophthalmus rhombus, Bos Taurus, Homo sapiens</i>) were used as an out-group. Bootstrap value <50 are not shown. The sequences used to construct phylogeny trees of c-type lysozymes are shown in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0067469#pone-0067469-t001" target="_blank">Table 1</a>.
