New preprint! We unexpectedly discovered that some Caenorhabditis species delete parts of their somatic genome early in development, which fragments their chromosomes and eliminates key germline genes. Multiple lines of evidence suggest this bizarre process was present in the ancestors of C. elegans
Figure with three panels. Left: phylogenetic tree of Caenorhabditis species, highlighting those with programmed DNA elimination. Middle: plot showing chromosomal locations of eliminated DNA. Right: Images showing DNA fragments being eliminated during early development.
