Vitamin B12 induces memory of predation through vitellogenin provisioning

Nutritional effects can alter organismal phenotypes and influence trait inheritance over generations. This study shows that bacteria-derived vitamin B12 induces a predatory mouth form and its transgenerational memory in a developmentally plastic nematode. This effect acts through increased vitellogenin transcription and nutrient provisioning.

Extracellular proteostasis prevents aggregation during pathogenic attack

A systematic analysis of the proteostasis network of secreted proteins in Caenorhabditis elegans identifies numerous regulators of protein homeostasis outside the cell, and highlights the contribution of extracellular proteostasis to host defence.

Chromatin remodelling and antisense-mediated up-regulation of the developmental switch gene eud-1 control predatory feeding plasticity

In the nematode Pristionchus pacificus, a developmental switch, the sulfatase eud-1, controls mouth-form plasticity. Here, the authors show that mutations in two conserved histone modifying enzymes mimic the eud-1 phenotype, in part mediated by an antisense eud-1RNA, resulting in the absence of one mouth-form

Chromosome fusions repatterned recombination rate and facilitated reproductive isolation during Pristionchus nematode speciation

Genomic analyses show that two independent fusions involving the same chromosome altered recombination patterns and contributed to reproductive isolation between two Pristionchus nematodes.
