Lateral Replacement Of The Lux Operon In A Vibrio Isolated From The Intestine Of A Coral Reef Fish, Melissa Lee Whyte
Theses and Dissertations
In a screening of bioluminescent bacteria isolated from the intestines of coral reef fish, two strains (designated D6 and M1) were identified that have a luxA gene sequence significantly different from those of other Vibrio species. Phylogenetic analysis of several housekeeping genes, as well as toxR, shows that D6 and M1 branch within a bioluminescent clade (designated the “D1 group,” isolated at the same time and place as D6 and M1) that is a close sister group to Vibrio harveyi. However, whereas the luxA genes of the D1 group are >98% identical to V. harveyi luxA, the luxA genes of …
