Molecular Phylogenetic analysis.

<p>The evolutionary history was inferred by using the Maximum Likelihood method based on the JTT matrix-based model [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0118779#pone.0118779.ref023" target="_blank">23</a>]. The tree with the highest log likelihood (-2145.5939) is shown. Initial tree(s) for the heuristic search were obtained automatically by applying Neighbor-Join and BioNJ algorithms to a matrix of pairwise distances estimated using a JTT model, and then selecting the topology with superior log likelihood value. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. All positions containing gaps and missing data were eliminated. There were a total of 455 positions in the final dataset. Evolutionary analyses were conducted in MEGA5.2 [<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0118779#pone.0118779.ref024" target="_blank">24</a>].
