Uncovering the role of nutritional rhythms in the squid-vibrio symbiosis
An essential character of a successful bacterial symbiosis is that the host does not fail to sustain its proper microbial partner, nor does the microbe overgrow its host’s tissues. To achieve this critical balance, the squid, Euprymna scolopes carefully controls the proliferation of its bioluminescent partner, Vibrio fischeri, on a daily cycle that involves the periodic provision of different sources of nutrition to the bacterial population. While the basis of some of these rhythmic activities have been revealed the processes underlying the ability of the host to maintain its symbiont population in a metabolically active growth stasis (MAGS) are only now coming into focus, providing clues to how symbiotic partners can turn potential sources of fitness lose (e.g., sharing of nutrients, or reducing growth rates) into the basis of a mutual success.
