Following UV irradiation of Bacillus subtilis there is a coordinate induction of: 1) a new protein, 2) a W-reactivation system, 3) a DNA modification system, and 4) prophages. These functions are induced following UV irradiation of repair proficient bacteria and mutants deficient in excision repair

Competent B. subtilis are more UV sensitive than the non-competent population of the culture. This increased sensitivity is lose in mutants unable to induce the 'SOS system' (recA1,, recG13), in mutants defective in the induction of prophage PBSX (xin), and in late stage competent cells. Moreover, b
The validity of in vivo fluorometric assays was ascertained for phage and bacterial DNA measurements. The following parameters were determined by this simple technique. The DNA content of dividing cells of Bacillus subtilis 168/2 was 2.65 times higher than in resting cells. Assuming that resting cel
