Webb. What might this regulatory system look like (use Vibrio fischeri as a model; 6 pts)? Vibrio fischeri uses quorum sensing to determine when cell density is sufficient to produce light. Light from a single bacterium is not useful so it is more beneficial for many bacteria to luminesce together.
