Scientists have uncovered a surprising twist in how bacteria share genes—including those that spread antibiotic resistance. Tiny virus-like particles called gene transfer agents (GTAs), once ancient viral invaders, have been repurposed by bacteria into delivery systems that shuttle DNA between neighboring cells. The study reveals a key control hub of three genes, dubbed LypABC, that triggers bacterial cells to burst open and release these DNA-packed couriers.
