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

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.
