How and why myxobacteria talk to each other.

In response to starvation, myxobacteria build multicellular fruiting bodies that contain many thousands of cells and that have particular species-specific shapes. To coordinate fruiting body development, the myxobacterial cells signal to each other. The timing of and cellular responses to these signals help to give form to the fruiting body. Following identification of several signal molecules, important transcriptional regulators and other signals have recently been identified. Steps on signal transduction pathways have also been defined.
