Programmed DNA Elimination in the Nematode Caenorhabditis auriculariae

Co-organized by：Grant-in-Aid for Transformative Research Areas (A) "Dynamic Reproductive Lifespan" and AMED-ASPIRE "Germ Cell Dynamics and Transgenerational Health Risks" Life continues across generations by transmitting genomes through germ cells. Yet inheritance is never perfectly faithful. Genomes change at multiple scales, from point mutations to chromosome-level rearrangements and karyotype variation (aneuploidy), and these changes can emerge as somatic phenotypes in subsequent generations. Sometimes they cause disease; sometimes they fuel evolution. In some organisms, genome alterations are developmentally programmed and woven into the life cycle. In this symposium, we explore how diverse organisms, from protozoans to plants and humans, navigate this maze-balancing genome stability with plasticity-and still succeed in carrying life forward.
