We stumbled upon an unusual gene called 'rqua' in the genome of some freshwater sponges. In microbes, this gene confers the ability to make a ubiquinone analog - rhodoquinone - which can help the respiratory chain run without oxygen.

Looking for some advice on statistical tests/tools to compare host:symbiont co-evolution - what are the minimum number of host and symbiont representatives you need? Can you detect co evolution in a clade where we really only have 2-5 closely related host species?

We did it! We caught Starship #transposons moving between #fungal species in the lab, including between species separated by ~100my. We think Starships are a mediator of HGT in fungi, akin to conjugative elements in bacteria. Check out the preprint. www.biorxiv.org/content/10.1...
