Quorum sensing in bacteria.
Quorum sensing is the regulation of gene expression in response to fluctuations in cell-population density. Quorum sensing bacteria produce and release chemical signal molecules called autoinducers that increase in concentration as a function of cell density. The detection of a minimal threshold stimulatory concentration of an autoinducer leads to an alteration in gene expression. Gram-positive...
متن کاملSigMol: repertoire of quorum sensing signaling molecules in prokaryotes
Quorum sensing is a widespread phenomenon in prokaryotes that helps them to communicate among themselves and with eukaryotes. It is driven through quorum sensing signaling molecules (QSSMs) in a density dependent manner that assists in numerous biological functions like biofilm formation, virulence factors secretion, swarming motility, bioluminescence, etc. Despite immense implications, dedicat...
متن کاملQuorum Sensing Signaling Molecules Produced by Reference and Emerging Soft-Rot Bacteria (Dickeya and Pectobacterium spp.)
BACKGROUND Several small diffusible molecules are involved in bacterial quorum sensing and virulence. The production of autoinducers-1 and -2, quinolone, indole and γ-amino butyrate signaling molecules was investigated in a set of soft-rot bacteria belonging to six Dickeya or Pectobacterium species including recent or emerging potato isolates. METHODOLOGY/PRINCIPAL FINDINGS Using bacterial bi...
متن کاملVisualizing Bacteria Quorum Sensing
Large populations of bacteria communicate by sending into the environment some specific signalling molecules. A bacterium will sense the population density by the concentration of the signalling molecule. This process, known as “quorum sensing”, is used in this paper to show the emergent behaviour of a bacterium colony in various circumstances. The biochemistry associated with quorum sensing ha...
متن کاملQuorum-Sensing Signal Disperses Bacteria from Biofilms
Biofilms are complex bacterial communities that range from bioluminescent pools in oceans to plaque buildup on teeth. These communities use quorum-sensing signals to modify their behaviors for optimal resilience against potential threats. Now researchers who study biofilms that cohabitate with marine sponges have discovered a quorum-sensing signal that controls the formation of the flagellum, a...
