Sex-like DNA exchange in starving bacteria occurs over 100 times more often than spontaneous mutations

Дата публикации: 01-10-2026 16:00:24

How do bacteria adapt when resources run low? ISTA researchers have found that, under starvation stress, E. coli can use bacteriophages and CRISPR-Cas immunity to transfer and incorporate DNA, accelerating genetic reshuffling. The process resembles a primitive form of sexual reproduction and may help bacterial populations adapt to changing conditions. The findings were published in Molecular Biology and Evolution.
