Control of cell division in Escherichia coli: Regulation of transcription of ftsQA involves both rpoS and SdiA-mediated autoinduction

摘要

The conditioning of culture medium by the production of growth-regulatory substances is a well- established phenomenon with eukaryotic cells. It has recently been shown that many prokaryotes are also capable of mod- ulating growth, and in some cases sensing cell density, by production of extracellular signaling molecules, thereby al- lowing single celled prokaryotes to function in some respects as multicellular organisms.
