Ecological feedback in quorum-sensing microbial populations can induce heterogeneous production of autoinducers [PDF]
eLife, 2017 Autoinducers are small signaling molecules that mediate intercellular communication in microbial populations and trigger coordinated gene expression via ‘quorum sensing’.

Quantifying the integration of quorum-sensing signals with single-cell resolution. [PDF]
PLoS Biology, 2009 Cell-to-cell communication in bacteria is a process known as quorum sensing that relies on the production, detection, and response to the extracellular accumulation of signaling molecules called autoinducers.

The Effect of Anabiosis Autoinducers on the Bacterial Genome [PDF]
Microbiology, 2002 The mutagenic activity of chemical analogues of microbial anabiosis autoinducers (the autoregulatory d1 factors of cell differentiation), which act to inhibit cell proliferation, to enhance cell tolerance, and to induce the transition of cells to anabiotic state, was studied using the Ames test.

Quinolones: from antibiotics to autoinducers [PDF]
FEMS Microbiology Reviews, 2011 Since quinine was first isolated, animals, plants and microorganisms producing a wide variety of quinolone compounds have been discovered, several of which possess medicinally interesting properties ranging from antiallergenic and anticancer to antimicrobial activities.

Optimal census by quorum sensing. [PDF]
PLoS Computational Biology, 2015 Quorum sensing is the regulation of gene expression in response to changes in cell density. To measure their cell density, bacterial populations produce and detect diffusible molecules called autoinducers.

Peptide autoinducers in bacteria [PDF]
Microbiology, 2009 The review classifies and analyzes the literature data on bacterial peptide autoinducers (AIs), responsible for intra- and interspecies communication (quorum sensing) between bacterial populations. The most important families of peptide AI are discussed, including a large group of bacteriocins, subdivided into lantibiotics (class I), unmodified heat ...

Phage-Encoded LuxR-Type Receptors Responsive to Host-Produced Bacterial Quorum-Sensing Autoinducers [PDF]
mBio, 2019 Quorum sensing (QS) is a process of cell-to-cell communication that bacteria use to orchestrate collective behaviors. QS relies on the cell-density-dependent production, accumulation, and receptor-mediated detection of extracellular signaling molecules ...
