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.

Localization of polyketide synthase encoding genes to the toxic dinoflagellate Karenia brevis [PDF]

Phytochemistry, 2005
Karenia brevis is a toxic marine dinoflagellate endemic to the Gulf of Mexico. Blooms of this harmful alga cause fish kills, marine mammal mortalities and neurotoxic shellfish poisonings. These harmful effects are attributed to a suite of polyketide secondary metabolites known as the brevetoxins.

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.

Horizontal gene transfer in chromalveolates

BMC Evolutionary Biology, 2007
Background Horizontal gene transfer (HGT), the non-genealogical transfer of genetic material between different organisms, is considered a potentially important mechanism of genome evolution in eukaryotes. Using phylogenomic analyses of expressed sequence

Effects of Multiple Karenia brevis Red Tide Blooms on a Common Bottlenose Dolphin (Tursiops truncatus) Prey Fish Assemblage: Patterns of Resistance and Resilience in Sarasota Bay, Florida

Frontiers in Marine Science, 2021
Red tide blooms caused by the toxic dinoflagellate Karenia brevis are natural disturbance events that occur regularly along Florida’s west coast, often resulting in massive fish kills and marine mammal, seabird, and sea turtle mortalities.

The Relationship Between Wavemaker Utilization and Karenia brevis Growth Rate

, 2021
Karenia brevis is a toxic dinoflagellate that can accumulate into red tide blooms, linked to adverse environmental, economic, and human health costs. At the Florida Mote Red Tide Initiative program, a state-of-the-art mitigation testing facility attracts

Temporal variations of caspase-3 like protein activity in cultures of the harmful dinoflagellates Karenia brevis and Karenia mikimotoi

, 2010
To better understand the role of caspase-like proteins in the cellular activities of harmful dinoflagellates, cultures of Karenia brevis and Karenia mikimotoi were monitored over a 56-day period.
