Five new <i>Caenorhabditis</i> species from Indonesia provide exceptions to Haldane's rule and partial fertility of interspecific hybrids Open
Given the interest in the biogeography and diversity of the Caenorhabditis genus, we established a collection of these nematodes from field surveys on 4 Indonesian islands. We isolated over 60 Caenorhabditis strains belonging to 10 species…

Natural variation in infection specificity of Caenorhabditis briggsae isolates by two RNA viruses Open
Antagonistic relationships such as host-virus interactions potentially lead to rapid evolution and specificity in interactions. The Orsay virus is so far the only horizontal virus naturally infecting the nematode C . elegans . In contrast,…

Genome-wide association and environmental suppression of the mortal germline phenotype of wild <i>C. elegans</i> Open
The animal germline lineage needs to be maintained along generations. However, some Caenorhabditis elegans wild isolates display a mortal germline phenotype, whereby the lineage becomes sterile after several generations at 25°C. We used a …

Vertical transmission in <i>Caenorhabditis</i> nematodes of RNA molecules encoding a viral RNA-dependent RNA polymerase Open
Here, we report on the discovery in Caenorhabditis nematodes of multiple vertically transmitted RNAs coding for putative RNA-dependent RNA polymerases. Their sequences share similarity to distinct RNA viruses, including bunyaviruses, narna…

Comparative genomics of 10 new<i>Caenorhabditis</i>species Open
The nematode Caenorhabditis elegans has been central to the understanding of metazoan biology. However, C. elegans is but one species among millions and the significance of this important model organism will only be fully revealed if it is…

View article: Pristionchus nematodes occur frequently in diverse rotting vegetal substrates and are not exclusively necromenic, while Panagrellus redivivoides is found specifically in rotting fruits
Pristionchus nematodes occur frequently in diverse rotting vegetal substrates and are not exclusively necromenic, while Panagrellus redivivoides is found specifically in rotting fruits Open
The lifestyle and feeding habits of nematodes are highly diverse. Several species of Pristionchus (Nematoda: Diplogastridae), including Pristionchus pacificus, have been reported to be necromenic, i.e. to associate with beetles in their da…

The Local Coexistence Pattern of Selfing Genotypes in <i>Caenorhabditis elegans</i> Natural Metapopulations Open
To study the interplay of rare outcrossing and metapopulation structure, we focus on the nematode Caenorhabditis elegans. Its remarkably low outcrossing rate is at the extreme end of the spectrum for facultative selfing organisms. At the d…
