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…

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 :)

After a 24-hours journey, ready for #phyllosphere meeting in #okinawa #oist !

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!

Jordanne winning

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! 😇

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

Spread the word! Methylorubrum is no more! Thread below (1/4):

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