Somatic Programmed DNA Elimination is widespread in free-living Rhabditidae nematodes

Abstract

In this manuscript, the authors investigate programmed DNA elimination (PDE) across nematodes using a large-scale cytological approach. This work is potentially significant because it expands PDE beyond a few known nematodes to a much broader set of Rhabditidae species, providing an important resource for investigating PDE's evolutionary origins and functions. The strength of evidence, however, is incomplete; the technique used to evaluate PDE is insufficient to provide unambiguous support for the phenomenon, so additional methods, such as genomic sequencing from a few species spanning the range of elimination levels, would be required to confirm these findings. This research would be of interest to geneticists, evolutionary biologists, and those working on the regulation of genome integrity.
