Who knew ammonia-oxidizing archaea could be “flexitarians”? Our new study in Science Advances shows that #AOA living inside marine sponges can assimilate branched-chain amino acids, an unexpected talent that may even shape how they interact with their hosts 🧽🤝🦠 🎉 www.science.org/doi/10.1126/...

Branched-chain amino acid assimilation enables mixotrophy of ammonia-oxidizing archaeal sponge symbionts
Marine sponges and ammonia-oxidizing archaea (AOA) represent one of the earliest animal-microbe symbioses. AOA are considered metabolically constrained chemolithoautotrophs that remove nitrogenous was...

I did not do justice to the great work of @bcoltman.bsky.social on MetaCoOc in this thread. A manuscript describing the tool fully, and a stable release of the code, are in preparation. In the meantime, the code can be found here: github.com/bcoltman/met...

In addition, the environmental metadata is included in the amino acid sequence toolkit (AASTK) SQL database, and can be directly accessed using the Meta command. Thus, any dataset of GlobDB derived AA sequences can be annotated with their primary environments. More on this here: globdb.org/aastk

This nice summary by @michiwagner4.bsky.social makes it easy to fit my post in a few characters. Amplicon sequencing is still an affordable and quick way to get good insights into who lives in your samples. Our new primers make sure your vision is 20/20. Try em, and contact me if you have questions!
