Figure 3

Nuclear rRNA gene phylogeny for Panagrolaimus. Cladogram shown is a 80% bootstrap consensus tree for NJ analysis of aligned 18S and 28S rRNA sequences from Panagrolaimus and select outgroup nematode species and strains. The MP phylogeny was highly congruent with the NJ phylogeny shown – see Additional files 1 and 2. Node-specific bootstrap values (1,000 replicates for each analysis) are shown, with NJ values over MP values. All strains and species historically considered as members of the Panagrolaimus genus are indicated by the brackets. Arrows denote the positions of two rhabditid strains initially misidentified as Panagrolaimus. Blue lines indicate parthenogenetic strains and green lines indicate hermaphroditic strains of Panagrolaimus. H. gingivalis also reproduces parthenogenetically in infected horses. DD13 and DD18 are two strains isolated from Newport, OR USA that are closely related to Rhabditophanes sp. KR3021. All other outgroup sequences were retrieved from Genbank.
