Diverse Bacterial PKS Sequences Derived From Okadaic Acid-Producing Dinoflagellates

Marine Drugs, 2008
Okadaic acid (OA) and the related dinophysistoxins are isolated from dinoflagellates of the genus Prorocentrum and Dinophysis. Bacteria of the Roseobacter group have been associated with okadaic acid producing dinoflagellates and have been previously ...

A Rare Case of Hypersensitivity Pneumonitis due to Florida Red Tide

Case Reports in Pulmonology, 2019
Florida red tides occur annually due to proliferation of the marine dinoflagellate Karenia brevis, which produces neurotoxins known as brevotoxins. Inhalational exposure to brevotoxins usually results in upper airway symptoms only.

Differences in growth and toxicity of Karenia [PDF]

, 2006
Harmful algal blooms (HABs) in the Gulf of Mexico are primarily caused by dense aggregations of the dinoflagellate species, Karenia brevis. Karenia brevis produces a highly toxic neurotoxin, brevetoxin which has been shown to cause Neurotoxic Shellfish ...

Exposure to the Florida red tide dinoflagellate, Karenia brevis, and its associated brevetoxins induces ecophysiological and proteomic alterations in Porites astreoides - Fig 3

, 2020
Kinetics of larval settlement and survival following exposure to either ambient seawater, methanol (MeOH), brevetoxins (PbTx) or Karenia brevis; for either 24, 48 and 72-hours: (A) percent survival, and (B) percent settlement. Bars represent ± 1 SE.

Transcriptomic response of the red tide dinoflagellate, Karenia brevis, to nitrogen and phosphorus depletion and addition

BMC Genomics, 2011
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.

Total Synthesis and Structural Confirmation of Brevisamide, a New Marine Cyclic Ether Alkaloid from the Dinoflagellate Karenia brevis

, 2016
The first total synthesis of brevisamide (1) has been accomplished in 21 linear steps starting from cis-but-2-ene-1,4-diol. A synthetic highlight is the Suzuki−Miyaura coupling between an ether ring fragment and a dienol side chain. This result confirmed
