High Nutritional Conditions Influence Feeding Plasticity in Pristionchus pacificus and Render Worms Non-Predatory. [PDF]

J Exp Zool B Mol Dev Evol
Developmental plasticity, the ability of a genotype to produce different phenotypes in response to environmental conditions, has been subject to intense studies in the last four decades.

Characterization of Heat Shock Protein Expression and Its Application to Temporal Gene Expression in the Nematode Pristionchus pacificus. [PDF]

Dev Growth Differ
Temporal gene expression systems are widely used to examine gene functions at specific developmental stages. One method applied in temporal gene expression systems in many organisms is the heat-inducible gene expression system, which utilizes a heat ...

Biosynthesis of modular signaling molecules requires functional diversification of carboxylesterases in Pristionchus pacificus [PDF]

Communications Biology
The entomophilic roundworm Pristionchus pacificus produces a group of complex ascaroside pheromones (e.g., ubas#1), which are built with various intermediates originating from primary metabolic pathways. However, the exact biosynthetic pathways resulting

cGMP-dependent pathway and a GPCR kinase are required for photoresponse in the nematode Pristionchus pacificus. [PDF]

PLoS Genetics
Light sensing is a critical function in most organisms and is mediated by photoreceptor proteins and phototransduction. Although most nematodes lack eyes, some species exhibit phototaxis.

Comparative genomics and community curation further improve gene annotations in the nematode Pristionchus pacificus [PDF]

BMC Genomics, 2020
Background Nematode model organisms such as Caenorhabditis elegans and Pristionchus pacificus are powerful systems for studying the evolution of gene function at a mechanistic level. However, the identification of P.

Spatial and temporal heterogeneity alter the cost of plasticity in Pristionchus pacificus. [PDF]

PLoS Comput Biol
Phenotypic plasticity, the ability of a single genotype to produce distinct phenotypes under different environmental conditions, has become a leading concept in ecology and evolutionary biology, with the most extreme examples being the formation of ...

Characterization of the Pristionchus pacificus "epigenetic toolkit" reveals the evolutionary loss of the histone methyltransferase complex PRC2. [PDF]

Genetics, 2023
Comparative approaches have revealed both divergent and convergent paths to achieving shared developmental outcomes. Thus, only through assembling multiple case studies can we understand biological principles. Yet, despite appreciating the conservation –

Starvation resistance in the nematode Pristionchus pacificus requires a conserved supplementary nuclear receptor. [PDF]

Zoological Lett, 2023
Nuclear hormone receptors (NHRs) are a deeply-conserved superfamily of metazoan transcription factors, which fine-tune the expression of their regulatory target genes in response to a plethora of sensory inputs.

Multiple Pristionchus pacificus genomes reveal distinct evolutionary dynamics between de novo candidates and duplicated genes. [PDF]

Genome Res, 2022
The birth of new genes is a major molecular innovation driving phenotypic diversity across all domains of life. Although repurposing of existing protein-coding material by duplication is considered the main process of new gene formation, recent studies ...

Comparative reconstruction of the predatory feeding structures of the polyphenic nematode Pristionchus pacificus. [PDF]

Evol Dev, 2022
Pristionchus pacificus is a nematode model for the developmental genetics of morphological polyphenism, especially at the level of individual cells. Morphological polyphenism in this species includes an evolutionary novelty, moveable teeth, which have ...
