| Title | Broad taxonomic sampling of mitochondrial cytochrome c oxidase subunit I does not solve the relationships between Rotifera and Acanthocephala |
| Abstract | The phylogenetic relationships within Syndermata (Acanthocephala + Rotifera) are still unresolved. Cladistic morphological analyses support monophyly of Rotifera and Eurotatoria (Bdelloidea + Monogononta), while molecular phylogenies of 18S, 28S, COI, hsp82 and EST propose different topologies, with at least six contrasting scenarios. All these phylogenies are characterized by poor taxon sampling; thus, our aim is to solve the relationships within Syndermata sampling as many sequences as possible from one single locus. We reconstructed phylogenetic relationship using more than 1000 sequences of COI. We performed Maximum Likelihood and Bayesian phylogenetic reconstructions on amino acid alignments, using either Gnathostomulida or Platyhelminthes as an outgroup, and then we performed SH tests to provide confidence on the best phylogenetic hypotheses. All four major clades (Acanthocephala, Bdelloidea, Monogononta and Seisonidea) are always highly supported. The basal relationship among the four clades is not consistently resolved by any of the phylogenetic reconstructions; nevertheless, there is a strong support for a clade of Acanthocephala + Bdelloidea from the SH tests, in agreement with other phylogenies from ribosomal genes and EST analyses.
