Natural monobacterial environments modulate viral infection in Caenorhabditis elegans

This study investigates how natural bacterial environments affect Caenorhabditis elegans susceptibility to Orsay virus, finding that most bacteria reduce infection while some increase it, independent of antiviral mechanisms.

Genome-wide association and environmental suppression of the mortal germline phenotype of wild C. elegans

This study identifies a genetic basis for a mortal germline phenotype in wild C. elegans and shows that environmental factors and non-genetic memory can suppress it.

Bacterial filamentation is an in vivo mechanism for cell-to-cell spreading

This study identifies bacterial filamentation as an in vivo mechanism for cell-to-cell spreading between intestinal epithelial cells in the nematode Oscheius tipulae.

Natural genetic variation drives microbiome selection in the Caenorhabditis elegans gut

This study identifies natural genetic variation in C. elegans that drives microbiome assembly by influencing immune, xenobiotic, and metabolic signaling pathways.

Balancing selection maintains hyper-divergent haplotypes in C. elegans

The paper shows that balancing selection maintains genetic diversity in hyper-divergent regions of C. elegans, enabling adaptation despite selfing.

CeMbio - The C. elegans microbiome resource

The paper introduces CeMbio, a simplified natural microbiota for C. elegans, enabling causal studies of host-microbiome interactions through a resource with culturable strains and associated tools.

A broad mutational target explains an evolutionary trend

The paper identifies a broad mutational target as the cause of high mutational variance in the P3.p cell fate among Caenorhabditis nematodes, explaining an evolutionary trend.

Noda-like RNA viruses infecting Caenorhabditis nematodes: sympatry, diversity and reassortment

The paper identifies a new RNA virus infecting Caenorhabditis nematodes, describes co-infections and reassortment patterns, and shows host-virus genotype interactions affecting competition.

Selection and gene flow shape niche-associated copy-number variation of pheromone receptor genes

The paper shows that copy-number variation of pheromone receptor genes in C. elegans is shaped by selection and gene flow, contributing to differences in pheromone responses across habitats.

Why would parthenogenetic females systematically produce males who never transmit their genes to females?

The paper investigates a reproductive strategy in the nematode Mesorhabditis belari where parthenogenetic females produce males that do not pass on their genes to females, and shows this strategy is efficient if sons mate with their sisters.

Pristionchus nematodes occur frequently in diverse rotting vegetal substrates and are not exclusively necromenic, while Panagrellus redivivoides is found specifically in rotting fruits

The paper investigates the ecological niches of Pristionchus and Panagrellus nematodes, finding they feed on decomposing vegetal matter and are transported by various arthropods, challenging the notion that they are exclusively necromenic.
