Temperature-sensitive sporulation caused by a mutation in the Bacillus subtilis secY gene.
A thermosensitive sporulation mutant of Bacillus subtilis containing a mutation in the secY gene was isolated and characterized. No asymmetric septum specific to the sporulation was detected by electron microscopy at the nonpermissive temperature, indicating that the block occurred at a very early stage of sporulation. Furthermore, competence development in the mutant cell was affected even at ...
متن کاملSuppression of temperature-sensitive sporulation of a Bacillus subtilis elongation factor G mutant by RNA polymerase mutations.
A class of rifampin-resistant (rfm) mutations of Bacillus subtilis suppresses the temperature-sensitive sporulation of a fusidic acid-resistant mutant. FUS426, which has an altered elongation factor G. The rfm mutation suppressed only the sporulation defect caused by the elongation factor G mutation, but could not suppress other types of induced sporulation defects. Genetic and biochemical anal...
متن کاملNew types of RNA polymerase mutations causing temperature-sensitive sporulation in bacillus subtilis.
A single site mutant of Bacillus subtilis with a streptovaricin-resistant RNA polymerase has been isolated; this mutation caused temperature-sensitive sporulation, but had no effect on vegetative growth. The mutant (ts710) temperature-sensitive period irreversibly affected the middle and late stages of sporulation. Mutant cells grown at the nonpermissive temperature exhibited abnormal serine pr...
متن کاملSporulation of Bacillus subtilis in Continuous Culture
Sporulation of Bacillus subtilis 168 was studied in chemostat cultures. Sporulation occurred at high frequency under limitation of growth by glucose or the nitrogen source in minimal medium, whereas rates of sporulation were low for Mg'+, phosphate, citrate, or tryptophan limitation. Sporulation was found at all growth rates tested, and the incidence of spores increased with decrease in growth ...
