Episodic selection and the maintenance of competence and natural transformation in Bacillus subtilis.

Genetics - 1 Apr 2009

Johnsen P J, Dubnau D, Levin B R

Abstract excerpt

We present a new hypothesis for the selective pressures responsible for maintaining natural competence and transformation. Our hypothesis is based in part on the observation that in Bacillus subtilis, where transformation is widespread, competence is associated with periods of nongrowth in otherwise growing populations. As postulated for the phenomenon of persistence, the short-term fitness cost associated with...
