Quorum Sensing

Bacteria communicate through autoinducers (AIs) - small signaling molecules that accumulate as population grows. When AI concentration exceeds a threshold, cells synchronously activate gene expression for collective behaviors like bioluminescence (Vibrio fischeri), virulence, and biofilm formation.
