🚨 New preprint! 🧬

𝐏𝐡𝐚𝐠𝐞-𝐩𝐥𝐚𝐬𝐦𝐢𝐝𝐬 (𝐏-𝐏𝐬) are fascinating elements: both 𝐭𝐞𝐦𝐩𝐞𝐫𝐚𝐭𝐞 𝐩𝐡𝐚𝐠𝐞𝐬 and 𝐩𝐥𝐚𝐬𝐦𝐢𝐝𝐬 ➡️ tricky to detect.

We present 𝐭𝐲𝐏𝐏𝐢𝐧𝐠 — the first 𝐢𝐝𝐞𝐧𝐭𝐢𝐟𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐚𝐧𝐝 𝐜𝐥𝐚𝐬𝐬𝐢𝐟𝐢𝐜𝐚𝐭𝐢𝐨𝐧 𝐭𝐨𝐨𝐥 🛠️designed specifically for P-Ps:
✅ Accurate
✅ Sensitive
✅ Easy to use

We also had an extraordinary session on phage-driven coevolutionary dynamics. Talks by @fredoleroux.bsky.social and her incredible datasets on vibrio phages, phage-plasmids, phage satellites and even phage-plasmid satellites & @clara-inrae.bsky.social on the phageome of apricot trees

Together, we show how #evolutionary history and #ecological ubiquity, more than #local-adaptation, shape phages–bacteria networks in plant-associated environments. 🌱🦠🧬

Both #defence-systems and #prophages contributed to phage resistance.
For one bacterial phylogroup, strains with more defence systems were infected by fewer phages.
Prophages didn’t strictly block infection but seemed to modulate phage efficacy in complex ways.

Both bacterial phylogeny and phage taxonomy influenced the structure of the phage–bacteria interaction network, alongside the observed nestedness.

We tested 23 #phages from diseased #apricot trees against 44 #𝑃𝑠𝑒𝑢𝑑𝑜𝑚𝑜𝑛𝑎𝑠 𝑠𝑦𝑟𝑖𝑛𝑔𝑎𝑒 strains from diseased plants, healthy plants, and nearby habitats. Instead of local adaptation, we found a strongly nested network, reflecting the broad ecological range of 𝑃. 𝑠𝑦𝑟𝑖𝑛𝑔𝑎𝑒.

New preprint out! 🧬🦠🌱

What shapes #phage–bacteria #networks in #plant environments?
- Ecological origins of bacteria and phages?
- Phage taxonomy?
- Bacterial phylogeny?
- #Prophages? #Defence-systems?

Excited 🥳 to share our latest work on gut phages!
Big thanks to @epcrocha.bsky.social, Erick D, Camille d'H, @fplazaonate.bsky.social, Quentin LB, and all others involved for support and contributions! 🙌

Here's what we found 🤓

Finally on Blue sky ☄️

So proud, grateful, and a bit sentimental as I share this special moment of my thesis defense ! 🦠🧫🌱

A heartfelt thank you to my 3 amazing supervisors @clara-inrae.bsky.social @dbszane.bsky.social @Annette Bérard, and the wonderful defense committee ✨

Congratulations to Dr. Chloé Feltin (still not on Bluesky) on an outstanding PhD defense and her pioneering work on the "Diversity and Interactions of Pseudomonas syringae Phages in Agricultural Environments". #proudPI #phages #Psyringae #INRAE

After many years in the making, here is our host range #phage paper with #ecology, #evolution and #biocontrol perspectives published in Molecular Ecology! @phimresearch.bsky.social‬ @inrae-pv.bsky.social‬ #PVBMT #JulianGarneau onlinelibrary.wiley.com/doi/10.1111/...
