Identification of sporulation genes in Bacillus anthracis highlights similarities and significant differences with Bacillus subtilis. [PDF]

PLoS Biology
The molecular basis of endospore formation in the model gram-positive bacterium Bacillus subtilis has been investigated for over half a century. Here, using high throughput and classical genetic approaches, we performed a comparative analysis of ...

Identification of diacetonamine from soybean curd residue as a sporulation-inducing factor toward Bacillus spp. [PDF]

AMB Express, 2017
Under bioassay-guided investigation, a sporulation-inducing factor (SIF) toward Bacillus spp. was searched for in methanol (MeOH) extracts of soybean curd residues, and diacetonamine (1) was identified as the active compound.

Mfd deficiency decreases the abundance of complete transcripts of sporulation genes and alters sporogenesis and the structure of dormant Bacillus subtilis spores [PDF]

Frontiers in Microbiology
Sporulation is a survival mechanism employed by Firmicutes, including Bacillus subtilis, when facing stressful conditions of growth (e.g., starvation). In this bacterium, the transcription repair coupling factor, Mfd, has been shown to play pivotal roles

Sporulation genes associated with sporulation efficiency in natural isolates of yeast. [PDF]

PLoS ONE, 2013
Yeast sporulation efficiency is a quantitative trait and is known to vary among experimental populations and natural isolates. Some studies have uncovered the genetic basis of this variation and have identified the role of sporulation genes (IME1, RME1 ...

Prediction of sporulating Firmicutes from uncultured gut microbiota using SpoMAG, an ensemble learning tool [PDF]

PeerJ
Sporulation represents a key adaptive strategy among Firmicutes, facilitating bacterial persistence under environmental stress while mediating host colonization, transmission dynamics, and microbiome stability.

c-di-GMP Inhibits Early Sporulation in Clostridioides difficile

mSphere, 2021
The formation of dormant spores is essential for the anaerobic pathogen Clostridioides difficile to survive outside the host gastrointestinal tract. The regulatory pathways and environmental signals that initiate C.

SUB1 Plays a Negative Role during Starvation Induced Sporulation Program in Saccharomyces cerevisiae. [PDF]

PLoS ONE, 2015
Saccharomyces cerevisiae Sub1 is involved in several cellular processes such as, transcription initiation, elongation, mRNA processing and DNA repair. It has also been reported to provide cellular resistance during conditions of oxidative DNA damage and ...

Mechanism insights into bacterial sporulation at natural sphalerite interface with and without light irradiation: The suppressing role in bacterial sporulation by photocatalysis

Environment International, 2022
Unveiling the mechanisms of bacterial sporulation at natural mineral interfaces is crucial to fully understand the interactions of mineral with microorganism in aquatic environment. In this study, the bacterial sporulation mechanisms of Bacillus subtilis

Identification of orphan histidine kinases that impact sporulation and enterotoxin production by Clostridium perfringens type F strain SM101 in a pathophysiologically-relevant ex vivo mouse intestinal contents model.

PLoS Pathogens, 2023
When causing food poisoning or antibiotic-associated diarrhea, Clostridium perfringens type F strains must sporulate to produce C. perfringens enterotoxin (CPE) in the intestines. C.

A Novel Prophage-like Insertion Element within yabG Triggers Early Entry into Sporulation in Clostridium botulinum

Viruses, 2023
Sporulation is a finely regulated morphogenetic program important in the ecology and epidemiology of Clostridium botulinum. Exogenous elements disrupting sporulation-associated genes contribute to sporulation regulation and introduce diversity in the ...
