Plasmids are associated with very variable fitness costs in their different bacterial hosts. But, what is the contribution of each of the plasmid-genes in these host-specific effects? Study led by
@jorgesastred.bsky.social, @sanmillan.bsky.social and myself! 1/14

Plasmids promote antimicrobial resistance through Insertion Sequence-mediated gene inactivation.
Combining experimental and computational approaches, we unveil how two of the most prevalent bacterial MGE accelerate the evolution of AMR. 🧵👇🏻

Excludons are pairs of overlapping genes that block each other’s expression (basically, reverse operons).
We built a tool to identify them in bacterial genomes using transcriptomic data, in an awesome collab led by Iñigo Lasa and Álvaro San Martín.

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! 🧵👇

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!
