Best tree of the Spirotrichea inferred by two-gene combined sequences (Atub-SSU).

Abstract

<p>Bootstrap values for branches of the ML tree is given on nodes. The scale bar corresponds to 5 substitutions per 100 nucleotide positions. Dargyrome patterns and natural habitats are given after species name of euplotids by symbols. Clades I-IV for euplotids were designated according to Petroni <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0040635#pone.0040635-Petroni1" target="_blank">[42]</a> and Yi et al. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0040635#pone.0040635-Yi4" target="_blank">[38]</a>.</p
