Acquisition of bioluminescent trait by non-luminous organisms from luminous organisms through various origins

Beware glowing cadavers: bioluminescence of nematode symbiont Photorhabdus protects nematode-infected host cadavers from nocturnal scavengers

“…Deterrence is unlikely to have been the function of bioluminescence in the bacteria from which Photorhabdus acquired its lux operon, as there is evidence that in the marine environment, a constant glow is attractive (Zavilgelsky and Shakulov, 2018). A plausible scenario is that the gene transfer occurred within a crustacean; bioluminescent marine bacterial species occur as pathogens of many crustacea (Nealson and Hastings, 1979;Ramesh and Bessho-Uehara, 2021), and Photorhabdus can infect littoral amphipods and isopods (Mauleón et al, 2006). Bioluminescence may have been maintained by in the terrestrial environment by protecting infected hosts against innately photophobic scavengers such as slugs, and/or by aposematically reinforcing pre-existing chemical defences of Photorhabdus.…”

“…Amongst the biochemical benefits that have been suggested are the detoxification of reactive oxygen species (Timmins et al, 2001) or the promotion of DNA repair (Czyz et al, 2000), but the likely importance of ecological functions involving perception by some other organisms is increasingly acknowledged (Nealson and Hastings, 1979;Zavilgelsky and Shakulov, 2018;Timsit et al, 2021). Many marine species of bioluminescent bacteria reside in specialised light organs of higher organisms (fish and squid) where they clearly provide light in return for nutrients from their host, whilst other marine species are postulated to use light to attract consumers that provide a medium for growth and a means of dispersal (Nealson and Hastings, 1979;Widder, 2010;Tanet et al, 2020;Ramesh and Bessho-Uehara, 2021). Photorhabdus spp.…”

Theoretical Study on the Formation and Decomposition Mechanisms of Coelenterazine Dioxetanone

“…Bioluminescence is a natural phenomenon in which biological organisms produce light through chemical reactions, widespread in oceans 1,2 (such as jellyfish, 3 cypridina, 4,5 luminescent fish, 6,7 etc.). Over the past decades, bioluminescence has received great attention due to the high signal-to-noise ratio and high bioluminescence quantum yields.…”

Over the past decades, bioluminescence has received great attention due to the high signal-to-noise ratio and high bioluminescence quantum yields. − These advantages of bioluminescence systems make them capable of being successfully applied in real-time monitoring of cell dynamics, gene reporter and regulation, , enzyme immunoassays, molecular imaging, − monitoring of protein interactions, and intracellular Ca 2+ measurements. , …”

Isolation and Identification of Luminescent Bacteria in Deep Sea Marine Organisms from Sicilian Waters (Mediterranean Sea)

“…The presence of symbiotic bacteria also seems to be necessary for the correct morphogenesis and development of luminous organs, and in many cases, the relationship is obligate [32][33][34]. More interestingly, the relationship was proven to have a certain grade of specificity since animals are able to select the specific symbiont bacteria [35,36] and actively eliminate non-luminous bacteria. In the association between Aliivibrio fischeri and the bobtail squid Euprymna scolopes, the host was demonstrated to be able to detect at a molecular and physiological level if its symbionts are bioluminescent or not and to reject non-luminescent strains of A. fischeri [37,38].…”
