CRISPR–Cas impedes archaeal mating

The early identification of repetitive genomic loci in Haloferax species was instrumental in igniting interest in CRISPR–Cas systems. Now, work in this genus has revealed an important role of CRISPR–Cas in reducing an unusual form of inter-species archaeal mating that occurs by cell fusion.
