Introduction Vibrio fischeri is a bacterium found in a variety of marine life environments. It typically lives in symbiosis with other marine animals found in its environment. Vibrio fischeri is able to have symbiotic relationship with other species because of its ability to give off light, a phenomenon called Bioluminescence. V. fischeri symbiotic relationship exists because the light they produce assists the host organism from casting a shadow allowing it to become undetectable to predators. Bioluminescence is caused by the transcription triggered by the presence of an autoinducer. Once the autoinducer reaches high enough concentration it triggers the luciferin-lucefase process which produces the light. The Lux operon is a set of genes which is responsible for activating this process. This Lux operon is organized into two oppositely transcribed regions. The right Lux operon which contains A-E, and the left which contains LuxR. Although being transcribed in opposite directions makes it impossible for transcription to take place on the same stand
