Pristionchus pacificus (Nematode, PS312) (El_Paco_fix)

NOTE: The genome sequence and annotation for P. pacificus are updated in Ensembl Metazoa infrequently. For the latest genome and annotation, please visit WormBase ParaSite (for an Ensembl-oriented view), or WormBase. The data here corresponds with WormBase WS279.

About Pristionchus pacificus

Pristionchus pacificus is a small, free-living roundworm, which is found on several continents and is associated with scarab beetles and Colorado potato beetles. It is part of the diplogastrids and it is estimated to have diverged from C. elegans 200-300 million years. It, therefore, shares many experimental advantages with C. elegans and is being used as a model organism for developmental biology and ecological studies, particularly in studies involving the analysis of vulval formation.
