Prokaryotes use quorum sensing (QS) for communication. This study maps microbial cell-cell communication across 15,297 genomes, revealing widespread LsrB receptor roles in gene regulation and biofilm formation.
Area of Science:
- Microbiology
- Genomics
- Biochemistry
Background:
- Cell-cell communication is vital for prokaryotic survival and reproduction.
- Quorum sensing (QS) is a key prokaryotic communication mechanism.
- Detailed catalogs of microbial communication are lacking.
Purpose of the Study:
- To create a comprehensive map of microbial cell-cell communication.
- To expand the understanding of the AI-2 signal in microbiomes.
- To investigate the role of LsrB receptors in prokaryotes.
Main Methods:
- Analysis of 15,297 prokaryotic genomes.
- Identification of LsrB receptor distribution across bacterial phyla.
- Gene expression analysis in *Streptomyces coelicolor*.
- International prospective study of microbial communication models.
Main Results:
- LsrB receptors are present in 15 bacterial phyla.
- LsrB regulates genes for siderophore biosynthesis and biofilm formation in *S. coelicolor*.
- Microbial communication models were studied across diverse habitats.
Conclusions:
- Microbial communication is a widespread and crucial phenomenon.
- This work provides a foundation for large-scale microbial community studies.
- Understanding AI-2 signaling is expanded within microbial consortia.
