🚨🚨New paper out in @natcomms.nature.com!!

Come for the first large-scale analysis of plasmid copy number across species,
stay for one of the most intriguing results of my lab: universal scaling laws in plasmid biology! 📈🧬

Universal rules govern plasmid copy number - Nature Communications
Plasmids exhibit a broad range of sizes and copies per cell, and these two parameters appear to be negatively correlated. Here, Ramiro-Martínez et al. analyse the copy number of thousands of diverse b...

New paper alert! 🚨

Plasmids promote bacterial evolution through a copy number-driven increase in mutation rate.

We combine theory, simulations, experimental evolution, and bioinformatics to demonstrate that mutation rates scale with plasmid copy number.

Let's dive in! 🧵👇
Plasmids promote bacterial evolution through a copy number-driven increase in mutation rate
Plasmids are autonomously replicating DNA molecules that stably coexist with chromosomes in bacterial cells. These genetic elements drive horizontal gene transfer and play a fundamental role in bacter...

Do plasmids evolve faster 🐇, slower 🐢, or just like chromosomes 🧬?

In our new paper, we tackled this question using theory, simulations, bioinformatics, and experiments!

👇 Check out all the details in Paula’s thread!

Hint: 🐇 (most of the time)

Just migrated here from twitter! Hello everyone.

Also, I've just put up a super simple (and free) to use APP to streamline experiment design and result analysis of 96 (or 384) wells plate experiments for my lab pals.

You can try it here: rosettier.streamlit.app

Feedback is very welcome 😁!

Very excited to have this paper officially out. This one is pretty special... Unfortunately, @kevinwoodum.bsky.social passed away when this paper was in its final stages. He was my biggest supporter, and I miss him deeply as a mentor and friend.
Evolution of antibiotic resistance #AMR can lead to collateral resistance/sensitivity to other drugs; @jeffmaltas.bsky.social &co show that these effects can fluctuate over time, needing precise timing & stochastic control models to optimize treatment strategies 🧪 @plosbiology.org plos.io/3C2Ao1y

Excited to share the first preprint from my lab, collaborating with the fantastic @sanmillan.bsky.social 's lab, led by the amazing Jorge Sastre. We've demonstrated how insertion sequences encoded in plasmids promote bacterial adaptation. This project has been incredibly fun!
