Vitamin B12 induces memory of predation through vitellogenin provisioning

|
By Shiela Pearl Quiobe, Ata Kalirad, Raphaela Zurheide, Hanh Witte, Christian Rödelsperger, Ralf J. Sommer
| Nature Verified
Abstract Nutritional effects on trait inheritance are widespread in animals including human famines, representing some of the most severe environmental influences on organismal phenotypes and can be transmitted over generations. However, the chemical nature of the stimuli inducing such memory remains elusive.

Diet-derived vitamin B12 induces transgenerational inheritance of nematode predation through elevated vitellogenin provisioning

|
By Shiela Pearl Quiobe, Ata Kalirad, Hanh Witte, Raphaela Zurheide
| BioRxiv
Abstract Dietary and nutritional effects can alter organismal phenotypes and influence trait inheritance over generations, so-called transgenerational epigenetic inheritance. However, the chemical nature of the stimuli and the downstream events inducing such memory remain largely elusive.

High Nutritional Conditions Influence Feeding Plasticity in Pristionchus pacificus and Render Worms Non‐Predatory

|

| Wiley Online Library Verified
1 Introduction Developmental plasticity allows organisms to alter their developmental trajectory to execute distinct phenotypes in response to environmental cues with polyphenisms representing the most remarkable form of plasticity by exhibiting environment-sensitive alternative phenotypes without intermediate forms (West-Eberhard 2003).
