Plasmid-amplified comS enhances genetic competence and suppresses sinR in Bacillus subtilis.

The establishment of genetic competence in Bacillus subtilis is controlled by a vast signal transduction network involving the products of genes that function in several postexponential-phase processes. Two of these proteins, SinR and DegU, serve as molecular switches that influence a cell's decision to undergo either sporulation or genetic competence development. In order to determine the role...

A plasmid-encoded phosphatase regulates Bacillus subtilis biofilm architecture, sporulation, and genetic competence.

Bacillus subtilis biofilm formation is tightly regulated by elaborate signaling pathways. In contrast to domesticated lab strains of B. subtilis which form smooth, essentially featureless colonies, undomesticated strains such as NCIB 3610 form architecturally complex biofilms. NCIB 3610 also contains an 80-kb plasmid absent from laboratory strains, and mutations in a plasmid-encoded homolog of ...

Genetic Competence Drives Genome Diversity in Bacillus subtilis

Prokaryote genomes are the result of a dynamic flux of genes, with increases achieved via horizontal gene transfer and reductions occurring through gene loss. The ecological and selective forces that drive this genomic flexibility vary across species. Bacillus subtilis is a naturally competent bacterium that occupies various environments, including plant-associated, soil, and marine niches, and...

Natural genetic competence in Bacillus subtilis natto OK2.

We isolated a Bacillus subtilis natto strain, designated OK2, from a lot of commercial fermented soybean natto and studied its ability to undergo natural competence development using a comG-lacZ fusion at the amyE locus. Although transcription of the late competence genes was not detected in the B. subtilis natto strain OK2 during competence development, these genes were constitutively transcri...

Bacillus subtilis YqjG is required for genetic competence development.

Members of the evolutionary conserved Oxa1/Alb3/YidC family have been shown to play an important role in membrane protein insertion, folding and/or assembly. Bacillus subtilis contains two YidC-like proteins, denoted as SpoIIIJ and YqjG. SpoIIIJ and YqjG are largely exchangeable, but SpoIIIJ is essential for spore formation and YqjG cannot complement this activity. To elucidate the role of YqjG...
