The temperate bacteriophages of Bacillus subtilis differ dramatically in their response to the induction of the SOS system during the development of competence and following DNA damage. While all temperate bacteriophages are induced following DNA damage, the "naive" bacteriophages (i.e., phi105 and SPO2) are also induced during the development of competence. On the other hand, "smart" bacteriophages (i.e., phi3T and SPbeta) are not induced during the development of competence, and furthermore, once competence has developed, these prophages can no longer be induced by DNA damage.
枯草芽孢杆菌的温和噬菌体在感受态发育过程中以及DNA损伤后对SOS系统诱导的反应存在显著差异。虽然所有温和噬菌体在DNA损伤后都会被诱导,但“幼稚”噬菌体(即phi105和SPO2)在感受态发育过程中也会被诱导。另一方面,“聪明”噬菌体(即phi3T和SPbeta)在感受态发育过程中不会被诱导,而且,一旦感受态形成,这些原噬菌体就不再能被DNA损伤诱导。
