Genome rearrangements in radiation-resistant bacteria

A number of bacterial, archaeal, and eukaryotic species are known for their resistance to ionizing radiation. One of the challenges these species face is a potent environmental source of DNA double-strand breaks, potential drivers of genome structure evolution. Efficient and accurate DNA double-strand break repair systems have been demonstrated in several unrelated radiation- resistant species and are putative adaptations to the DNA damaging environment. Such adaptations are expected to compensate for the genome- destabilizing effect of environmental DNA damage and may be expected to result in a more conserved gene order in radiation-resistant species. However, we show that rates of genome rearrangements, measured as loss of gene order conservation with time, are higher in radiation- resistant species in multiple, phylogenetically independent groups of bacteria. Furthermore, we explore whether detected high rearrangement rates in radiation-resistant species constitute a survival strategy or are a passive consequence of environmental DNA damage.
