(8) During the process of endospore formation in Bacillus subtilis the appearance of the mother-cell transcription factor sigma K by conversion from its inactive precursor pro-sigma K is coupled to events under the control of the forespore transcription factor sigma G. This intercompartmental coupling is believed to be mediated by the products of a sporulation locus called spoI V F because certain bypass-of-forespore (bof) mutations that map at the spoI V F locus relieve the dependence of pro-sigma K processing on the action of sigma G in the forespore.

(14) Terminally located, heat-resistant endospores were formed on plates of an enriched agar medium supplemented with L-rhamnose.
(15) The relative abundance of endospores and vegetative cells as well as the protein distributions of these subpopulations may be readily determined from flow microfluorometry data.
(16) A new species, Bacillus naganoensis, is proposed for an obligately aerobic, moderately acidophilic, endospore-forming bacterium that produces a thermostable, aciduric pullulanase (EC 3.2.1.41).
(17) Deletion of sigE, the structural gene for the sporulation-induced RNA polymerase sigma factor, sigma E, prevented endospore formation by Bacillus subtilis.
(18) Because these obligate bacterial parasites of nematodes have not been cultured axenically, the taxonomic relationships described here for each species are based mainly on developmental morphology, fine structure of the respective sporangia and endospores, and their pathogenicity on nematode species.
(19) The results suggest that the crystal and endospore contain one or more common proteins.
(20) Cells were formed, which resembled bacterial endospores by their formation and structure; however, typical refractive spores with envelopes and cortex have not been detected.
