Theses and Dissertations
Bacterial bioluminescence is observed in over twenty known species, primarily in the family Vibrionaceae. However, only Vibrio fischeri and Vibrio harveyi bioluminescence expression mechanisms are well studied. In V. harveyi, expression of the lux operon is activated by the transcription factor LuxR (LuxRVH), resulting in bioluminescence. Homologs of LuxRVH in other Vibrio species have been shown to regulate transcription of a variety of genes. Three parallel quorum sensing pathways co-regulate the expression of LuxRVH. The first objective was to assess possible quorum sensing regulation of lux operon expression in V. cholerae, V. chagasii, …
