Further Insights into Brevetoxin Metabolism by de Novo Radiolabeling
Toxins, 2014 The toxic dinoflagellate Karenia brevis, responsible for early harmful algal blooms in the Gulf of Mexico, produces many secondary metabolites, including potent neurotoxins called brevetoxins (PbTx).

Zooplankton and Karenia brevis in the Gulf of Mexico [PDF]
, 2008 Blooms of the toxic dinoflagellate Karenia brevis are common in the Gulf of Mexico, yet no in situ studies of zooplankton and K. brevis have been conducted there. Zooplankton abundance and taxonomic composition at non-bloom and K.

Patterns in evolutionary origins of heme, chlorophyll a and isopentenyl diphosphate biosynthetic pathways suggest non-photosynthetic periods prior to plastid replacements in dinoflagellates [PDF]
PeerJ, 2018 Background The ancestral dinoflagellate most likely established a peridinin-containing plastid, which have been inherited in the extant photosynthetic descendants.

Transcriptomic Response of Karenia brevis to Environmental Stress [PDF]
, 2020 Karenia brevis is a toxic, marine phytoplankton that forms harmful algal blooms in the Gulf of Mexico. This toxicity is due to the production of ladder-frame polyketides known as brevetoxins, for which the production pathway and function in the cell are ...

Interaction of a dinoflagellate neurotoxin with voltage-activated ion channels in a marine diatom [PDF]
PeerJ, 2018 Background The potent neurotoxins produced by the harmful algal bloom species Karenia brevis are activators of sodium voltage-gated channels (VGC) in animals, resulting in altered channel kinetics and membrane hyperexcitability.
