Figure 4

Mitochondrial ND5 gene phylogeny for Panagrolaimus. Phylogram shows relationships among a subset of Panagrolaimus ND5 sequences (those able to be successfully amplified) inferred from NJ phylogenetic analysis (see Methods). Scale bar shows 0.05 substitutions per site. Bootstrap values resulting from NJ and MP analyses are shown for select nodes (e.g. those supporting PI, PIp and HI). Additional files 4 and 5 show complete phylograms with all bootstrap values for NJ and MP analyses, respectively. Blue lines indicate parthenogenetic strains and green lines indicate hermaphroditic strains.
