Role of Biomarkers in Monitoring Brevetoxins in Karenia brevis Exposed Shellfish. [PDF]
Monitoring and management programs for marine toxins in seafood depend on efficient detection tools for their success in protecting public health. Here we review current methods of detection for neurotoxic shellfish poisoning (NSP) toxins, and current knowledge in brevetoxin metabolism in shellfish.

De novo assembly and characterization of the transcriptome of the toxic dinoflagellate Karenia brevis. [PDF]
Karenia brevis is a harmful algal species that blooms in the Gulf of Mexico and produces brevetoxins that cause neurotoxic shellfish poisoning. Elevated brevetoxin levels in K. brevis cells have been measured during laboratory hypo-osmotic stress treatments. To investigate mechanisms underlying K. brevis osmoacclimation and osmoregulation and establish

Increased toxicity of Karenia brevis during phosphate limited growth: ecological and evolutionary implications. [PDF]
Karenia brevis is the dominant toxic red tide algal species in the Gulf of Mexico. It produces potent neurotoxins (brevetoxins [PbTxs]), which negatively impact human and animal health, local economies, and ecosystem function.

Osmotic stress triggers toxin production by the dinoflagellate Karenia brevis. [PDF]
With the increase in frequency of harmful algal blooms (HABs) worldwide, a better understanding of the mechanisms that influence toxin production is needed. Karenia brevis , the major HAB dinoflagellate in the Gulf of Mexico, produces potent neurotoxins, known as brevetoxins.

Osmotic stress does not trigger brevetoxin production in the dinoflagellate Karenia brevis. [PDF]
With the global proliferation of toxic harmful algal bloom species, there is a need to identify the environmental and biological factors that regulate toxin production. One such species, Karenia brevis , forms nearly annual blooms that threaten coastal regions throughout the Gulf of Mexico ...

Global analysis of mRNA half-lives and de novo transcription in a dinoflagellate, Karenia brevis. [PDF]
Dinoflagellates possess many physiological processes that appear to be under post-transcriptional control. However, the extent to which their genes are regulated post-transcriptionally remains unresolved.

Electroporation and lysis of marine microalga Karenia brevis for RNA extraction and amplification. [PDF]
We describe here a simple device for dielectrophoretic concentration of marine microalga Karenia brevis non-motile cells, followed by electric field-mediated lysis for RNA extraction. The lysate was purified using magnetic beads and pure RNA extracted.

Examination of the toxicity of a new group of <i>Karenia papilionacea</i> isolated from the Yellow Sea, China, to multiple species of marine aquatic animals. [PDF]
IntroductionThe dinoflagellate genus Karenia G. Hansen and Moestrup is notorious for forming harmful algal blooms (HABs), most of which can produce a variety of potent toxins (e.g., brevetoxins), killing fish and other aquatic animals above a certain ...

Transcriptomic response of the red tide dinoflagellate, Karenia brevis, to nitrogen and phosphorus depletion and addition. [PDF]
Background The role of coastal nutrient sources in the persistence of Karenia brevis red tides in coastal waters of Florida is a contentious issue that warrants investigation into the regulation of nutrient responses in this dinoflagellate.

Microbial and chemical dynamics of a toxic dinoflagellate bloom [PDF]
Harmful Algal Blooms (HABs) exert considerable ecological and economic damage and are becoming increasingly frequent worldwide. However, the biological factors underlying HABs remain uncertain.
