Genomic polymorphism in symbiotic populations of Photobacterium leiognathi.
Photobacterium leiognathi forms a bioluminescent symbiosis with leiognathid fishes, colonizing the internal light organ of the fish and providing its host with light used in bioluminescence displays. Strains symbiotic with different species of the fish exhibit substantial phenotypic differences in symbiosis and in culture, including differences in 2-D PAGE protein patterns and profiles of indig...
متن کاملRegulation of Bioluminescence in Photobacterium leiognathi Strain KNH6.
UNLABELLED Bacterial bioluminescence is taxonomically restricted to certain proteobacteria, many of which belong to the Vibrionaceae. In the most well-studied cases, pheromone signaling plays a key role in regulation of light production. However, previous reports have indicated that certain Photobacterium strains do not use this regulatory method for controlling luminescence. In this study, we ...
متن کاملComplete Genome Sequence of Photobacterium leiognathi Strain JS01
Photobacterium leiognathi is a bioluminescent symbiont of fish of the Leiognathidae family. Here, we present the full-genome sequence of P. leiognathi strain JS01, a strain isolated from a nonluminescent Loligo sp. squid of Singaporean origin. No finished genome sequence of this species is currently publicly available.
متن کاملDiversification of Two Lineages of Symbiotic Photobacterium
Understanding of processes driving bacterial speciation requires examination of closely related, recently diversified lineages. To gain an insight into diversification of bacteria, we conducted comparative genomic analysis of two lineages of bioluminescent symbionts, Photobacterium leiognathi and 'P. mandapamensis'. The two lineages are evolutionary and ecologically closely related. Based on th...
متن کاملDetermination of pyruvic acid concentration using a bioluminescence system from Photobacterium leiognathi.
A novel, highly sensitive and selective bacterial luminescence method for the detection of pyruvic acid (PA) is reported here. This method is based on a reaction system catalyzed by lactate dehydrogenase (LDH) with the bacterial luciferase-FMN:NADH oxidoreductase bioluminescence system in vitro. The reduced nicotinamide adenine dinucleotide (NADH) involved in the LDH reaction system could be qu...
