Please RT. 1x postdoc and 1xPhD position available in our group to study the role of NLR-like proteins in cellular development and antibiotic production in Streptomyces.
Postdoc: shorturl.at/f8NTN
PhD position: shorturl.at/qCFmN
Email me for more information.

It's out!! Great review on Terrabacteria led by @BasileBeaud and Najwa Taib with @ChrisBel70. So much to discover on envelope biogenesis and the diderm-to-monoderm transition in this understudied clade! @NatureRevMicro @institutpasteur @Fondation_BS Read👇rdcu.be/dSegH
Happy to share a chapter of my PhD thesis🐣! We review the diversity of the cell envelope in Terrabacteria which tell us a lot about outer membrane biogenesis and the diderm-to-monoderm transition. Thanks to my co-authors Najwa Taib @ChrisBel70 @SGribaldo

This is a very important paper suggesting that the Last Universal Common Ancestor of all living species lived 4.2 billion years ago. With Earth being only 4.5 billion years old, this suggests that life originated very soon after conditions were favorable.

Always fun to discuss with collaborators on Monday afternoon: Dennis Classen, @derozenleiden, @HelenaShomar, @pnleao, @BriegelAriane and...two members from @FrunzkeLab🦜🙃

🚨Super excited to share our pre-print describing how we used genomics to discover a family of anti-phage lanthipeptides from Actinobacteria 🦠
This marks a significant expansion in the number of bacterial natural products involved in chemical defense.

Excited to present this work on bacterial polyploidy from my previous postdoc!
Want to know about a genetic diversity strategy that is like having backup codes to unlock the perfect resistance combo? Read all about it (1/4) biorxiv.org/content/10.1101/…

I might be biased, but Streptomyces are pretty cool: They not only make lots of antibiotics but also secrete umbrella toxins to interact with their microbial neighbours. Streptomyces umbrella toxin particles block hyphal growth of competing species nature.com/articles/s41586-0…
