The relationships of the Nematoda.

Abstract

<p>This phylogeny is based on molecular phylogenetic analyses utilising the small subunit ribosomal RNA gene. The systematic names given by De Ley and Blaxter <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1001050#pbio.1001050-DeLey1" target="_blank">[55]</a>,<a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1001050#pbio.1001050-DeLey2" target="_blank">[56]</a> are given, as is the “clade” naming convention introduced by Blaxter et al. in 1998 <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1001050#pbio.1001050-Blaxter2" target="_blank">[52]</a>. More recently, Helder and colleagues <a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1001050#pbio.1001050-Holterman1" target="_blank">[53]</a>,<a href="http://www.plosbiology.org/article/info:doi/10.1371/journal.pbio.1001050#pbio.1001050-vanMegen1" target="_blank">[77]</a> have introduced a numerical clade name scheme: this is given in outlined letters below the relevant branches. Feeding mode, and animal and plant parasitic and vector associations, are indicated by small icons, and representative species are named for some groups. Species with a sequenced genome are indicated by an asterisk.</p
