Role of the Lux Operon in Bioluminescence

Introduction

The lux operon has long been studied for its unique gene product: bioluminescence. Found in the bacterium Vibrio fischeri, the lux operon is an essential part of the bacterium's genetic code. In fact, the bacterial bioluminescence produced by the Vibrio fischeri bacteria plays an essential role in many mutualistic relationships with other organisms. One such organism is the Hawaiian Bobtail Squid (Euprymna scolopes).
