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)

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...

New preprint led by @brunoluviano.bsky.social & Fernando Santos.

We show that filamentation enhances bacterial survival under toxic stress — not as collateral damage, but as a regulated morphological response.

TL;DR: Filamentation isn’t a symptom, it’s a strategy!

Thanks Thanks to @ayari.bsky.social for inviting me to present at @meehubs.bsky.social from the Cuernavaca hub. Got some great questions from the audience in other parts of the World!

Can we predict AMR evolution?? We sure can try! New study published today in PNAS
