Extremely happy to see the final version of our paper "The expression of integron arrays is shaped
by the translation rate of cassettes" out in @NatureComms 🥳!!! Thanks to the reviewers for their valuable feedback and suggestions!

Proud to share my latest PhD work! We found that in GBS, CRISPR-Cas9 immunity is integrated within the virulence regulatory network. This co-regulation, mediated by CovR—the major regulator of virulence—could enhance the immune repertoire during infection. https://t.co/CGArsxaB6i

I am please to announce that
@Navarro_PaulaP and I are organizing this year's @DMF_UNIL Impromptu Symposium on Bacterial Cell Biology. We are looking forward to an exciting day of science with a fantastic speaker lineup 🧫🦠🧬🔬❄️
Registration is open (using QR codes).

Interested in plasmid biology? Our new preprint is now available!!! 🚨

In this work, we analyzed thousands of diverse bacterial plasmids to characterize for the first time one of the most fundamental aspects of plasmid biology: Plasmid copy number. 1/7 👇

📢A new PhD student position in Bacterial Genetics is now open in my team @DMF_UNIL in beautiful Lausanne/Switzerland 🇨🇭
More information on that position and on the application procedure can be found here: https://t.co/dcdYM6aymV
Please RT.

Excited to share this preprint! Our multiscale approach has finally shed light on the essential roles of the structural protein HU in pneumococcal nucleoid dynamics. Thanks to all co-authors for their contribution to this collaborative work.

Great paper! Still warm. https://t.co/S7gt9hqEdO
So DciA ensures that the replisome starts bidirectionally! What about DnaC in other bacterial models? congrats to the authors!

[Florian Fournès @FlorianFournes]

💥 For DNA replication aficionado and others : this paper highlights a fascinating and new model of replication regulation in bacteria with atypical genome composition.

[Justine Collier @Justinec_Caulo]

Exciting news 🤩: Our article on the impact of DNA methylation in Agrobacteriumis now out in the NAR journal. https://t.co/uZR5zx2oyJ

[Justine Collier @Justinec_Caulo]

PhD Fellowships available at our Faculty in Lausanne/Switzerland. We are a host lab in someone is interested! https://t.co/1rlvAOraDQ via @unil

[Asha Mary Joseph @ashamjos]

Delighted to share this new preprint from Anjana Badrinarayanan @anjbadri lab.
By assessing replication dynamics at the level of single cells, we reveal the intricate relationship between nutrient status and rates of genome duplication in bacteria.

🎊 🍾I am delighted to announce that I have been promoted to Associate Professor @DMF_UNIL @FBM_UNIL 🥂🎉. It would never have been possible without the fabulous contribution of my many present and former lab members or without the support of my dear colleagues: thanks to all! 🥰

[Florian Fournès @FlorianFournes]

@BaptisteDarracq 👏👏👏👏👏👏👏👏

[Baptiste Darracq @BaptisteDarracq]

Our paper about integrons and their fascinating content is on biorXiv🤩Go check out Eloi's thread for a sneak peek of what these big fellas are capable of !

Find out how we developed a Prime editing tool in which cells either make a precise genetic change or die, ensuring that only successfully edited cells survive. Given its high efficiency and precision, the applications it offers are endless! 👇🏼
