Sociomicrobiology: Coexistence of conflict and cooperation in the squid light organ

The Hawaiian bobtail squid's Vibrio fischeri symbionts use quorum sensing for both bioluminescence and to modulate antagonism. New research finds quorum sensing unexpectedly represses V. fischeri's type 6 secretion system, highlighting intricate connections between cooperative and competitive microbial behaviors.
