The bioluminescence emitted by the marine bacterium Vibrio fischeri is a particularly striking result of individual microbial cells co-ordinating a group behaviour. The genes responsible for light production are principally regulated by the LuxR-LuxI quorum-sensing system. In addition to LuxR-LuxI, numerous other genetic elements and environmental conditions control bioluminescence production. Efforts to mathematically model the LuxR-LuxI system are providing insight into the dynamics of this autoinduction behaviour. The Hawaiian squid Euprymna scolopes forms a natural symbiosis with V. fischeri, and utilizes the symbiont-derived bioluminescence for certain nocturnal behaviours, such as counterillumination. Recent work suggests that the tissue with which V. fischeri associates not only can detect bioluminescence but may also use this light to monitor the V. fischeri population.
海洋细菌发光杆菌发出的生物光是单个微生物细胞协调群体行为的一个特别显著的结果。负责发光的基因主要受 LuxR-LuxI 群体感应系统调控。除了 LuxR-LuxI，许多其他遗传因素和环境条件控制着生物发光的产生。对 LuxR-LuxI 系统进行数学建模的努力为这种自动诱导行为的动态提供了深入了解。夏威夷乌贼 Euprymna scolopes 与发光杆菌形成了一种自然共生关系，并利用共生菌衍生的生物发光来进行某些夜间行为，例如对抗照明。最近的研究表明，发光杆菌与之相关的组织不仅可以检测生物发光，还可以利用这种光来监测发光杆菌的种群。
