Life History Responses and Gene Expression Profiles of the Nematode Pristionchus pacificus Cultured on Cryptococcus Yeasts. [PDF]
PLoS ONE, 2016 Nematodes, the earth's most abundant metazoa are found in all ecosystems. In order to survive in diverse environments, they have evolved distinct feeding strategies and they can use different food sources.

Natural variation of outcrossing in the hermaphroditic nematode
BMC Evolutionary Biology, 2009 Background Evolution of selfing can be associated with an increase in fixation of deleterious mutations, which in certain conditions can lead to species extinction.

Serotonin Drives Predatory Feeding Behavior via Synchronous Feeding Rhythms in the Nematode Pristionchus pacificus [PDF]
G3: Genes, Genomes, Genetics, 2017 Feeding behaviors in a wide range of animals are regulated by the neurotransmitter serotonin, although the exact neural circuits and associated mechanism are often unknown.

The Role of DAF-21/Hsp90 in Mouth-Form Plasticity in Pristionchus pacificus. [PDF]
Mol Biol Evol, 2017 Phenotypic plasticity is increasingly recognized to facilitate adaptive change in plants and animals, including insects, nematodes, and vertebrates. Plasticity can occur as continuous or discrete (polyphenisms) variation.

Food size and cGMP affects feeding behaviour in Pristionchus pacificus [PDF]
Journal of the International Society of Sports Nutrition, 2011 Methods For this study I used P. pacificus PS312, and the mutants Ppa-egl-4, which is a null mutation in the cGMP dependent protein kinase, and Ppa-obi-1, which is an oriental beetle pheromone insensitive mutant, and the double mutant Ppa-egl-4;obi-1. I tested these strains on plates containing no food and on E.coli OP50, HB101, Caulobacter crescentus (

Evolution of lateralized gustation in nematodes [PDF]
eLifeAnimals with small nervous systems have a limited number of sensory neurons that must encode information from a changing environment. This problem is particularly exacerbated in nematodes that populate a wide variety of distinct ecological niches but ...

A locus in Pristionchus pacificus that is responsible for the ability to give rise to fertile offspring at higher temperatures [PDF]
Biology Open, 2016 Temperature is a stress factor that varies temporally and spatially, and can affect the fitness of cold-blooded organisms, leading to a loss of reproductive output; however, little is understood about the genetics behind the long-term response of ...

Genome Announcement: Further Improved Genome Assembly of Parapristionchus giblindavisi [PDF]
Journal of NematologyNematodes such as Caenorhabditis elegans and Pristionchus pacificus are powerful models for associating phenotypes to genotypes. However, exploring the evolution of identified genetic loci requires a robust phylogenomic framework.

Pristionchus pacificus genomics: from genetics to genome sequence [PDF]
WormBook, 2006 Satellite systems are proving to be important players in understanding the differences between ontogenies during evolution. The satellite system P. pacificus, since its discovery nearly a decade ago (Sommer et al., 1996), has provided developmental biologists with new insights into various developmental processes (Eizinger and Sommer, 1997; Jungblut ...
