A cool genetic system to study site-pecific replication fork collapse and repair from the brilliant @winterhalterlab.bsky.social www.nature.com/articles/s41...

New pub. from the lab ! We discovered that potato tubers exert intense selective pressure during Dickeya solani infection, driving the rapid emergence of mutations in the sRNA ArcZ. These mutations lead to the appearance of "social cheaters" that sweep through the pop. in as few as 30 generations.

Great news! 🎊 www.theguardian.com/world/2025/d...

Le 1er janvier 2026, le CNRS coupera l’accès au Web of Science, Core Collection et Journal Citation Reports. Une nouvelle étape de sa politique en faveur de la science ouverte pour promouvoir des alternatives ouvertes, transparentes et responsables.

Cool work from Heath Murray's lab where they use Cas9 nickase to study how ssDNA breaks are repaired in Bacillus subtilis #MicroSky www.nature.com/articles/s41...

New paper alert 🚨 I am super happy about it, for many reasons! 👥 It was a great collaborative project with Calum @chgjohnston.bsky.social and J. Pablo Radicella, designed a long time ago (in the pre-AlphaFold era - can you imagine?) together with @polardlab.bsky.social and @raphguerois.bsky.social

Pleased to share our recent article in PNAS - a collaboration with @jessicaandreani.bsky.social & Pablo Radicella, with important roles played by many members of each team. A tripartite protein complex promotes DNA transport during natural transformation in Firmicutes www.pnas.org/doi/10.1073/...

Come and work with me and @ariannebabina.bsky.social on #Streptomyces evolution and antibiotic production Origins of a tangled bank: Adaptation and evolution in antibiotic-producing Streptomyces www.gla.ac.uk/postgraduate... please repost

New paper from our lab up on Biorxiv, showing how a toxin targets replication to induce competence. 👇

Offre de thèse disponible dans notre équipe au @mmsb-lyon.bsky.social Si vous êtes étudiant(e) en Master 2 et intéressé(e) par la génétique bactérienne, microscopie à épifluorescence et biochimie, contactez-nous et postulez à l'offre! Dossier pour le 13/06 Concours école doctorale E2M2: 8 et 9/07.

For those who are interested in all things 'transformation', here is a link to registration for the 6th edition of the Zoom on Griffith's Legacy, the 4th and 5th June 2025. griffiths2025.sciencesconf.org It has been fun co-organising this with Luisa Hiller. We hope to see you there!

Pleased to share a new preprint - a great collaboration with @jessicaandreani.bsky.social and the Guerois lab at I2BC, and the Radicella lab at the CEA. Using stuctural modelling, we reveal & validate a 3 protein complex involved in DNA import during transformation. www.biorxiv.org/content/10.1...

Let's start the Bsky adventure with a job post. Still about two weeks to apply to this postdoc position on "Molecular and Structural Biology of Membrane Biogenesis" in the labs @raffaeleieva.bsky.social ky.social and @fronzeslab.bsky.social slab.bsky.social in beautiful south-west of France!

Really proud of our new paper, my first as last author. We explored the importance of homologous recombination genes in transformation and genotoxic stress tolerance during competence. Give it a read/like! 🙂 journals.asm.org/doi/10.1128/...
