Table 3. P. redivivus orthology statistics.

Predicted proteins in P. redivivus	24,249
P. redivivus proteins in clusters	17,415
Clusters with P. redivivus proteins	9,156
Clusters without P. redivivus proteins	8,794
P. redivivus orphan proteins (unclustered)	6,834
N:N orthologous protein clusters	1,664
1:1 orthologous protein clusters	521
Orthologous protein clusters including all nematode taxa but no insect ortholog	281

The P. redivivus genome and transcriptome reveal 27,266 proteins. Of these, 443 proteins are conserved at a 1:1 ratio across seven other nematodes, listed in Table 6, and the insect outgroup N. vitripennis. Only 266 orthologous protein clusters in this data set were exclusively nematode proteins.
