This Review highlights how we can build upon the relatively new and rapidly developing field of research into bacterial quorum sensing (QS). We now have a depth of knowledge about how bacteria use QS signals to communicate with each other and to coordinate their activities. In recent years there have been extraordinary advances in our understanding of the genetics, genomics, biochemistry, and signal diversity of QS. We are beginning to understand the connections between QS and bacterial sociality. This foundation places us at the beginning of a new era in which researchers will be able to work towards new medicines to treat devastating infectious diseases, and use bacteria to understand the biology of sociality.

Tomasz, A. Control of the competent state in Pneumococcus by a hormone-like cell product: an example for a new type of regulatory mechanism in bacteria. Nature 208, 155–159 (1965). This paper was the first to provide evidence that an extracellular hormone-like molecule promoted bacterial group behaviour.
Nealson, K. H ., Platt, T. & Hastings, J. W. Cellular control of the synthesis and activity of the bacterial luminescent system. J. Bacteriol. 104, 313–322 (1970). This paper showed that the sudden increase of bioluminescence by mid-logarithmic Vibrio fischeri and Vibrio harveyi cultures required transcription and a self-produced factor, and this phenomenon was referred to as autoinduction.
