How do trees shape microbial evolution? New bioRxiv preprint from our former MSc student Jocelyn Lauzon with @skembel.bsky.social reveals host-driven adaptations of #Methylobacterium in the #phyllosphere using a #metapangenomic approach. Proud to see this work out! 🌳🌿🧫🧬 doi.org/10.64898/202...
Thank you to #SMBE2026 organizers for this great meeting in København! See you next year for #SMBE2027 in Québec City, Canada! smbe2027.org
Our article on the dark matter in the #phyllosphere in Systematic and applied Microbiology! #methylobacterium #lichenibacterium #lichenifustis #lichenihabitans and even more to discover in #Hyphomicrobiales (former Rhizobiales) inhabiting leave surfaces! www.sciencedirect.com/science/arti...
A phylogenomic and metagenomic meta-analysis of bacterial diversity in the phyllosphere lifts a veil on hyphomicrobiales dark matter
The phyllosphere, or above-ground part of plants, hosts diverse bacterial communities that play critical ecological roles and provide beneficial funct…

Check out our preprint on #Methylobacterium ’s relative, #Lichenibacterium (aka 1174-901-12), my new favorite bacteria from the #phyllosphere ! Thanks to @skembel.bsky.social and our students David Ross and Louis-Philippe St-Amand for this work! @biorxivpreprint.bsky.social doi.org/10.1101/2025...
Bye #CSPB2025 ! 🌿An inspiring conference packed with amazing plant science! Thanks to the organizers, @cspbscbv.bsky.social executive, and my team for making us proud! 💚 Special shoutout to Oussama from @leducq-lab.bsky.social / @eplopez.bsky.social for winning the Agrisera poster award! 🏆 #ProudPI
#scee2025 #csee2025 in Sherbrooke! Thanks @ilafores.bsky.social and @monaparizadeh.bsky.social for the invitation :)
16S rRNA is just like AI. If you don't know how to use it, just don't, or train first.
Congrats to our PhD candidate Oussama Yahmi for his 3rd place in the poster competition at Congres RQRAD 2025!
Edel Pérez-López 🇨🇦@edelplopez.bsky.social · last yr.So proud of our team at Congrès RQRAD 2025! Jordanne won 2nd🥈place in the oral competition, Oussama (Dir. @leducq-lab.bsky.social) took 3rd🥉place for his poster, and Joshua delivered an awesome presentation in French. Congratulations to all three of you for your outstanding performances! #ProudPI 🎉💚

Since the release of our perspective in the ISMEj (doi.org/10.1093/ismejo/wraf011), I realized that Methylorubrum and especially Methylobacterium pages in wikipedia desesperatly needed some updates... This is just a begining and other PPFM nerds are welcome to participate to this peer process! 😇
Spread the word! Methylorubrum is no more! Thread below (1/4): academic.oup.com/ismej/advanc...
Led astray by 16S rRNA: phylogenomics reaffirms the monophyly of Methylobacterium and lack of support for Methylorubrum as a genus
Abstract. Although the 16S (and 18S) rRNA gene has been an essential tool in classifying prokaryotes, using a single locus to revise bacteria taxonomy can

Stop relying only on #16S for bacteria taxonomy! Our last paper revoking #Methylorubrum as a genus and reinstating #Methylobacterium is out in the #ISMEjournal! doi.org/10.1093/isme...
