The morphological variation of process lengths can be applied for the reconstruction of salinity. The normal circadian bioluminescence rhythm and the expected changes in Luciferin Binding Protein abundance were arrested in L. polyedrum cysts. These tiny organisms glow like fireflies whenever they are stressed or otherwise agitated by surface tension and acidity. The seemingly magical imagery is actually anything but – it is caused by bioluminescent phytoplankton (Lingulodinium polyedrum). In Lingulodinium polyedrum, a single lcf gene has been identified, which is present in multiple copies organized as tandem repeats. It is armored, meaning it has a hard outer coating. These unicellular organisms rise to the surface at night to breed (blooming).

The normal circadian bioluminescence rhythm and the expected changes in Luciferin Binding Protein abundance were arrested in L. polyedrum cysts. Marasovic, I. The response of L. polyedrum to hydrodynamic stimulation was best characterized by wall shear stress; at similar values of wall shear … The blue light is a result of a luciferase enzyme (like firefly luciferase, but the enzyme in L. polyedrum shares no similarity with that of the firefly enzyme). (eds. More specifically, the color is caused by a chemical reaction that results from the movement of the algae. Photo: With kind permission by Christopher J. Wills, University of California , San Diego Phycologists have chosen a new alga of the year: the unicellular alga Lingulodinium polyedrum. This cyst was first described by Deflandre and Cookson in 1955 from the Miocene of Balcombe Bay, Victoria, Australia as: "Shell globular, subsphaerical or ellipsoidal with a rigid membrane, more brittle than deformable, covered with numerous long, stiff, conical, pointed processes resembling the blade of a dagger.

A circadian clock in Lingulodinium polyedrum has be shown to occur on a daily basis, and to regulate the mechanism of light-emission on at the level of gene expression . Emiliania huxleyi (2009) | In bioluminescent species light is emitted from small (0.4um) cell organelles, which in Lingulodinium polyedrum contain two proteins involved in light emission: dinoflagellate luciferase (LCF) and a substrate (luciferin)-binding protein (LBP). It’s a Bioluminescent Red Tide! The blue light is a result of a luciferase enzyme (like firefly luciferase, but the enzyme in L. polyedrum shares no similarity with that of the firefly enzyme). In Pyrocystis lunula, three different lcf genes can be distinguished, lcfA, lcfB and lcfC (Okamoto et al.
