Pristionchus pacificus: a well‐rounded nematode

BioEssays, 2006
AbstractNematodes pervade Earth's biosphere and occupy innumerable ecological niches. The role of Caenorhabditis elegans as a model for developmental processes has encouraged us to cultivate a second nematode, Pristionchus pacificus, as a comparative counterpoint to address questions in development, behavior and ecology in nematode evolution.

Pristionchus pacificus: an appropriate fondness for beetles

Nature Genetics, 2008
The nematode Pristionchus pacificus associates with one particular beetle and eats its rotting corpse. The report of the genome sequence of P. pacificus, the fifth nematode to be sequenced and a useful secondary nematode genetic model system, highlights genes that may have influenced the route to parasitism.

The Nematode Pristionchus pacificus Requires the Gβ and Gγ Proteins for Light Adaptation But Not For Light Avoidance

Zoological Science
Most organisms can sense and adapt to a wide range of light intensities. Although animals commonly use opsins for light detection, the nematode Pristionchus pacificus lacks conserved photoreceptors.

Vulva formation in Pristionchus pacificus relies on continuous gonadal induction

Development Genes and Evolution, 1999
One of the best known features of vulva development in Caenorhabditis elegans is the induction of vulval precursor cells by the gonadal anchor cell. Induction is crucial for the initiation of pattern formation within the C. elegans vulva equivalence group, and it is therefore surprising to find that this aspect of vulva formation, in particular, varies

Identity and functions of monoaminergic neurons in the predatory nematode Pristionchus pacificus reveal nervous system conservation and divergence

bioRxiv
Changes in neurotransmitter usage in homologous neurons may drive evolutionary adaptations in neural circuits across animal phylogeny. The predatory nematode Pristionchus pacificus can be used as a model system to examine nervous system evolution by ...
