Quorum sensing and starvation: signals for entry into stationary phase

Curr Opin Microbiol. 2000 Apr;3(2):177-82. doi: 10.1016/s1369-5274(00)00072-2.

Abstract

Quorum sensing occurs at high cell density in many microorganisms. It regulates specialized processes such as genetic competence, bioluminescence, virulence, and sporulation. However, recent evidence suggests that quorum-sensing may play a more central role in the physiology of bacteria, where quorum-sensing pathways converge with starvation-sensing pathways to regulate cell entry into stationary phase.
