Bacteria use molecular weapons such as toxins to outcompete rivals, but their horizontal gene transfer can undermine this advantage. This study shows that horizontal gene transfer of toxin plasmids is rare but the recipient bacteria can thrive under relaxed nutrient competition, reshaping bacterial competition dynamics.

Bacterial restriction-modification systems are responsible for protecting cells from foreign genetic material, for example, bacteriophages and plasmids. Immune systems require strict regulation, as bacteria, like humans, can have autoimmune reactions—an attack on their own DNA.
