Tn7 family transposons that include all of the guide RNA-directed transposons (CAST) are common in bacteria. We now find diverse representatives across archaea, with many in the Asgard group. Reviving an Asgard element confirmed the exciting behaviors of the family #MicroSky #TESky

Trying to define a “natural” condition can get you some heat in my experience. Nevertheless, a reasonable hypothesis that is out there is that locally beneficial genes tend to be on plasmids and other mobile elements. For example, antibiotic resistance in a hospital.

Joe Peters Lab @joepeterslab.bsky.social · 27/11/2024

This doesn't sound like what you are working with, but I have seen many labs rediscover Restriction and Modification Systems when they first try to set up conjugation systems because of incompatibilities with donor/host.
