The biochemistry and circadian regulation of luminescence in two Pyrocystis species, P. lunula Hulburt and P. noctiluca Murray et Haeckel, were compared with a well‐studied species, Gonyaulax polyedra Stein. All exhibit circadian rhythms and all have similar luciferins and luciferases. However, the Pyrocystis species lack a second protein involved in the reaction in Gonyaulax, the luciferin (substrate) binding protein, which sequesters the luciferin at the cytoplasmic pH and releases it upon… 

New Perspectives Related to the Bioluminescent System in Dinoflagellates: Pyrocystis lunula, a Case Study

TLDR
A review of the literature in relation to the molecular players responsible for bioluminescence in dinoflagellates, with particular interest in P. lunula, and a phylogenetic analysis of the conservation of protein sequence, structure and evolutionary pattern of these key players.

Diversity of the Luciferin Binding Protein Gene in Bioluminescent Dinoflagellates – Insights from a New Gene in Noctiluca scintillans and Sequences from Gonyaulacoid Genera

TLDR
Phylogenetic analyses showed that, in some species, the evolution of the luciferin binding protein gene was different from the organism's general phylogenies, highlighting the complex evolutionary history of dinoflagellate bioluminescence systems.

Circadian Rhythms in Dinoflagellates: What Is the Purpose of Synthesis and Destruction of Proteins?

TLDR
It is posits that synthesis and destruction constitutes a cellular mechanism to conserve nitrogen in an environment where the resource is limiting.

Two different domains of the luciferase gene in the heterotrophic dinoflagellate Noctiluca scintillans occur as two separate genes in photosynthetic species

TLDR
It is reported that the structural organization of the luciferase gene of Noctiluca scintillans is strikingly different from that of the seven luminous species previously characterized, all of which are photosynthetic.

Circadian Changes in Ribulose-1,5-Bisphosphate Carboxylase/Oxygenase Distribution Inside Individual Chloroplasts Can Account for the Rhythm in Dinoflagellate Carbon Fixation

TLDR
The rhythm in Rubisco distribution is causally related to the rhythm in carbon fixation and it is suggested that several mechanisms involving enzyme sequestration could account for the increase in the efficiency of carbon fixation.

Cell ultrastructural changes correlate with circadian rhythms in Pyrocystis lunula (Pyrrophyta)

TLDR
The complete serial reconstruction of P. lunula cells during both day and night phases is reported, the first four dimensional study of any dinoflagellate.

EFFECTS OF METALS AND ORGANIC CONTAMINANTS ON THE RECOVERY OF BIOLUMINESCENCE IN THE MARINE DINOFLAGELLATE PYROCYSTIS LUNULA (DINOPHYCEAE)1

TLDR
Investigation of the short‐term effects of metals and organic pollutants on the recovery of the bioluminescent potential in Pyrocystis lunula shows that it is sensitive to the reference contaminants tested and obtains highly reproducible results.

Theoretical Study of Dinoflagellate Bioluminescence

TLDR
The density functional calculation is employed and results agree with the experimental observations and indicate the luciferin or its analogue, rather than oxyluciferin, is the bioluminophore of dinoflagellate bioluminescence.

Involvement of actin and microtubules in regulation ofbioluminescence and translocation of chloroplasts in thedinoflagellate Pyrocystis lunula

TLDR
Results suggest that F-actin and microtubules are involved in the movements of chloroplasts and scintillons, and further experiments are needed to determine whether effects on bioluminescence were mediated by drug-induced failed translocations of scintsillons or chloroplast.

CIRCADIAN REGULATION OF BIOLUMINESCENCE IN THE DINOFLAGELLATE PYROCYSTIS LUNULA 1

TLDR
The results indicate that the circadian regulation of luciferase activity differs in the two species, and the glow in P. lunula differs markedly from that in G. polyedra in that it may fluctuate 5–10‐fold in intensity within a time frame of seconds.

The biological clock in Gonyaulax controls luciferase activity by regulating turnover.

Dinoflagellate bioluminescence: A comparative study of invitro components

TLDR
In vitro bioluminescence components of the dinoflagellates Gonyaulax polyedra, G. tamarensis, Dissodinium lunula, and Pyrocystis noctiluca were studied and the observations that D. lunula and P. noCTiluca apparently lack LBP and have luciferases with low MW single chains require further clarification.

Compartmentalization of algal bioluminescence: autofluorescence of bioluminescent particles in the dinoflagellate Gonyaulax as studied with image-intensified video microscopy and flow cytometry

TLDR
The endogenous fluorescence of the dinoflagellate alga Gonyaulax originates in vivo from discrete subcellular loci that are intrinsically fluorescent, and luciferin is localized within the cell at discrete loci from which the bioluminescence emanates.

The polypeptide components of scintillons, the bioluminescence organelles of the dinoflagellate Gonyaulax polyedra.

Scintillons, the bioluminescence organelles of Gonyaulax polyedra, were purified by isopycnic density gradient centrifugation until only low levels of contaminating chloroplasts and mitochondria were

The circadian bioluminescence rhythm of Gonyaulax is related to daily variations in the number of light-emitting organelles.

The number of scintillons, which are cellular organelles responsible for light emission in the marine alga Gonyaulax, were counted by both immunofluorescence and electron microscopic methods and

Circadian regulation of bioluminescence in Gonyaulax involves translational control.

TLDR
The LBP mRNA levels, as determined by in vitro translations and by RNA (Northern) hybridizations, do not vary over the daily cycle, indicating that circadian control of bioluminescence in this species is mediated by translation.

SPECIES OF OCEANIC DINOFLAGELLATES IN THE GENERA DISSODINIUM AND PYROCYSTIS: INTERCLONAL AND INTERSPECIFIC COMPARISONS OF THE COLOR AND PHOTON YIELD OF BIOLUMINESCENCE 1

TLDR
The data suggested that enzyme turnover occurred in the reactions producing light during mechanical stimulation of Dissodinium and Pyrocystis species, and produced much higher numbers of photons per cell nitrogen than Gonyaulax polyedra or Pyrodinium bahamense.
