Dynamical consequences of bandpass feedback loops in a bacterial phosphorelay. [PDF]
PLoS ONE, 2011 Under conditions of nutrient limitation, Bacillus subtilis cells terminally differentiate into a dormant spore state. Progression to sporulation is controlled by a genetic circuit consisting of a phosphorelay embedded in multiple transcriptional feedback

Structural, Metabolic and Evolutionary Comparison of Bacterial Endospore and Exospore Formation
Frontiers in Microbiology, 2021 Sporulation is a specialized developmental program employed by a diverse set of bacteria which culminates in the formation of dormant cells displaying increased resilience to stressors.

Transcriptional Profile of Bacillus subtilis sigF-Mutant during Vegetative Growth. [PDF]
PLoS ONE, 2015 Sigma factor F is the first forespore specific transcription factor in Bacillus subtilis and controls genes required for the early stages of prespore development. The role of sigF is well studied under conditions that induce sporulation. Here, the impact

Transcriptional profiling of the model organism "A. gossypii" : comparison of life cycle stages and transcription factor deletions [PDF]
, 2007 Experiments described in this PhD thesis used for the rst time custom-made oligonucleotide chips to substantially increase our knowledge and understanding of the model organism A. gossypii. Four sets of experiments of different scales were performed:

mBio, 2018 Bacillus anthracis is a Gram-positive bacillus that under conditions of environmental stress, such as low nutrients, can convert from a vegetative bacillus to a highly durable spore that enables long-term survival. The sporulation process is regulated by

SPORULATION IN DISTILLED WATER [PDF]
Journal of General Physiology, 1953 Spores are formed when vegetative cells of sporing aerobes are shaken with distilled water at 37°. These spores are derived from the small number of cells which survive lysis. The sporulation process involves increase and concentration of solid material in the cell, and is achieved at the expense of the products of lysis of 80 to 90 per cent of the ...

Sporulation conditions influence the surface and adhesion properties of Bacillus subtilis spores
Frontiers in Microbiology, 2023 Spore-forming bacteria of the Bacillus subtilis group are responsible for recurrent contamination of processing lines in the food industry which can lead to food spoilage. The persistence of B.

Inducible Expression of spo0A as a Universal Tool for Studying Sporulation in Clostridium difficile
Frontiers in Microbiology, 2017 Clostridium difficile remains a leading nosocomial pathogen, putting considerable strain on the healthcare system. The ability to form endospores, highly resistant to environmental insults, is key to its persistence and transmission.
