quorum sensing

quorum sensing

n.
A phenomenon in which a population of bacteria produces and responds to intercellular chemical signals whose concentration indicates the density of the population. When the density reaches a certain level, genes are expressed that allow for coordinated group behavior, as in bioluminescence or the formation of biofilms.
