摘要：

We constructed a Bacillus subtilis Marburg strain that harbors deletion mutations in all seven extracyto-plasmic 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.
