Title A viable Bacillus subtilis strain without functional extracytoplasmic function sigma genes.
Journal J. Bacteriol.
Abstract We constructed a Bacillus subtilis Marburg strain that harbors deletion mutations in all seven extracytoplasmic function (ECF) sigma genes. The strain shows wild-type growth at 37 degrees C both in a complex and in a synthetic medium and exhibits wild-type sporulation. ECF sigma genes of B. subtilis are dispensable as long as no stress is imposed, although they seem to be required for quick response to stresses.
