Vibrio fischeri communicate through a process known as quorum sensing, where they release and detect signaling molecules called autoinducers. When the population density of these bacteria increases, the concentration of autoinducers reaches a threshold that triggers a coordinated response, leading to changes in gene expression. This communication results in bioluminescence, allowing them to emit light, which can have various ecological roles, such as attracting mates or deterring predators. Ultimately, their communication facilitates group behavior that enhances their survival and adaptation in their environment.
how do the Vibrio fischeri communicate? What happens as a result of their communication?
