A report by Moré et al. (p. 1655) describes the biosynthesis of an autoinducer from Agrobacterium tumefaciens, a molecule that signals bacterial density of a culture (a quorum sensor). The Perspective by Kaiser reviews what is known about autoinducers from a number of microorganisms and speculates about their identity as predecessors of hormone-hormone receptor systems of eukaryotes.
