Summary
Strigolactones, plant hormones, modulate bacterial quorum sensing (QS) in the pathogen Vibrio cholerae. This discovery reveals new roles for strigolactones beyond plant signaling.
Area of Science:
- Plant biology
- Microbiology
- Biochemistry
Background:
- Strigolactones are crucial plant hormones involved in rhizosphere signaling.
- Recent research indicates strigolactones have diverse roles beyond plant development.
Purpose of the Study:
- To investigate the potential of strigolactones to influence bacterial communication.
- To determine if strigolactones affect quorum sensing (QS) in the human pathogen Vibrio cholerae.
Main Methods:
- Utilized Vibrio cholerae as a model organism.
- Assessed the impact of strigolactones on bacterial quorum sensing pathways.
Main Results:
- Strigolactones were found to modulate bacterial quorum sensing.
- Demonstrated a novel interaction between plant hormones and bacterial signaling.
Conclusions:
- Strigolactones possess the ability to regulate bacterial quorum sensing in Vibrio cholerae.
- This finding expands the known functions of strigolactones and suggests inter-kingdom signaling roles.

362
Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...

01:30Bacterial Signaling
39.3K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...

Bacterial growth is closely tied to nutrient availability, with cells proliferating exponentially under favorable conditions and entering a stationary phase when resources become scarce. This transition is mediated by a regulatory mechanism known as the stringent response, which allows bacteria to adapt to nutrient deprivation by modulating gene expression and metabolic activity.During nutrient scarcity, intracellular amino acid levels decline. It results in the accumulation of uncharged tRNAs...

01:17Gene Regulation During Sporulation
327
Sporulation is a complex developmental process that allows certain Gram-positive bacteria, such as Bacillus subtilis and Clostridium species, to survive extreme environmental conditions. This process is tightly regulated by a series of signaling cascades and transcriptional controls, ensuring the formation of a highly resistant endospore.Sporulation is triggered by unfavorable conditions, such as nutrient depletion, and is governed by a phosphorelay system. One of the sensor kinases, such as...

Bacteria have global regulatory systems that control several types of stress mechanisms. These include Pho regulon and the heat shock response, which are essential systems for environmental adaptation, such as nutrient limitation and proteotoxic stress. The Pho regulon and the heat shock response exemplify bacterial resilience, enabling rapid adaptation to fluctuating environmental conditions.Pho RegulonBacteria require phosphorus for essential cellular processes, including nucleic acid...
