Molecular cloning of a Bacillus subtilis gene involved in spore outgrowth.

A lambda Charon 4A derivative carrying the outB gene of Bacillus subtilis has been identified by transformation of a B. subtilis mutant temperature-sensitive in spore outgrowth. The cloned region is a single EcoRI fragment 14 kb in length. In addition to outB, the cloned DNA includes at least part of the amyE and aroI loci.
