Paper of the month: November 2014

  • Integration of prophages into coding sequences of the host genome results in loss of function of the interrupted gene. In B. subtilis 168, the SP-beta prophage is inserted into a uncharacterized spore polysaccharide synthesis gene, spsM. In vegetative cells, the lytic cycle is induced in response to DNA damage. In the process, the SP-beta prophage is excised from the genome to form phage particles. Now, Abe et al. demonstrate that the excision of the SP-beta prophage also occurs systematically during sporulation to reconstitute a functional spsM gene from the incomplete yodU and ypqP pseudogenes. Because phage excision is limited to the mother cell genome, and does not occur in the forespore genome, the SP-beta prophage is an integral part of the spore genome. Thus, after germination, the SP-beta prophage is propagated vertically to the progeny. The authors suggest their results indicate that the two pathways of SP-beta prophage excision support both the phage life cycle and normal sporulation of the host cells.
