A translational lacZ fusion of the Bacillus subtilis mscL gene that encodes the mechanosensitive channel of large conductance (MscL) was expressed at significant levels during log phase growth of B. subtilis, and the level of mscL-lacZ expression was increased 1.5-fold by growth in medium with high salt (1 M NaCl). However, in growth media with either low or high salt, mscL-lacZ expression fell drastically beginning in the late log phase of growth, and fell to even lower levels during sporulation, although a significant amount of beta-galactosidase from mscL to lacZ was accumulated in the developing spore. Deletion of mscL had no effect on B. subtilis growth, sporulation or subsequent spore germination. The DeltamscL strain also grew as well as the wild-type parental strain in medium with 1.2 M NaCl. While log phase wild-type cells grown with 1.2 M NaCl survived a rapid 0.9 M osmotic downshift, log phase DeltamscL cells rapidly lost viability and lysed when subjected to this same osmotic downshift. However, by the early stationary phase of growth, DeltamscL cells had become resistant to a 0.9 M osmotic downshift.
