Figure 1.
Maximum likelihood tree of diplogastrid SSU sequences. Sequences of 21 Pristionchus species ([17] and unpublished data) and 14 diplogastrid SSU sequences retrieved from the GenBank database or obtained from isolates described here were aligned manually with Rhabditoides inermis as outgroup. A maximum likelihood tree was reconstructed using the phylogeny.fr server [38]. GenBank accession codes are shown at taxon labels where available, strain designations are shown in parentheses. Bootstrap support values are indicated at nodes.
