Bacterial community affects toxin production by Gymnodinium catenatum. [PDF]
PLoS ONE, 2014 The paralytic shellfish toxin (PST)-producing dinoflagellate Gymnodinium catenatum grows in association with a complex marine bacterial community that is both essential for growth and can alter culture growth dynamics.

Temporal Variability of Virioplankton during a Gymnodinium catenatum Algal Bloom [PDF]
Microorganisms, 2020 Viruses are key biogeochemical engines in the regulation of the dynamics of phytoplankton. However, there has been little research on viral communities in relation to algal blooms.

Towards the Early Detection of Gymnodinium catenatum Algal Blooms in the Northern Gulf of California
Journal of Marine Science and Engineering, 2023 The annual occurrence of harmful algal blooms (HABs) of the dinoflagellate Gymnodinium catenatum in the northern Gulf of California (NGC) during winter and spring has negative ecological, economic, and social impacts on the local coastal population.

OCCURRENCE OF Gymnodinium catenatum IN THE GULF OF THAILAND
Marine Research in Indonesia, 2008 A clonal culture of Gymnodinium catenatum was established from a plankton sample collected from Leamthan, Chonburi Province, in the Upper Gulf of Thailand. The culture was maintained at 28±1°C under light intensity of 70 [tmol photons m-2 s-1 with 12:12 L:D cycle. Cells were harvested at late exponential phase and extracted with 0.03 M acetic acid. The

Multiplex qPCR Assay for Simultaneous Detection of Three PST-Producing Dinoflagellates in the East China Sea off Southern Korea [PDF]
BiologyParalytic shellfish toxins (PSTs) are produced by several toxic species of the dinoflagellate genera Alexandrium and Gymnodinium, and they pose significant threats to marine ecosystems and public health.

Revisiting the life cycle of Margalefidinium polykrikoides Group III. [PDF]
J PhycolAbstract Dinoflagellates produce cysts as a strategy to withstand environmental stressors, with nutrient depletion generally considered a key trigger for cyst production. Resting cysts are thick‐walled, typically composed of one to several layers, and characterized by a prolonged dormancy period.

Genomics study of the exposure effect of Gymnodinium catenatum, a paralyzing toxin producer, on Crassostrea gigas' defense system and detoxification genes. [PDF]
PLoS ONE, 2013 BACKGROUND: Crassostrea gigas accumulates paralytic shellfish toxins (PST) associated with red tide species as Gymnodinium catenatum. Previous studies demonstrated bivalves show variable feeding responses to toxic algae at physiological level; recently ...

Docking Simulation of the Binding Interactions of Saxitoxin Analogs Produced by the Marine Dinoflagellate Gymnodinium catenatum to the Voltage-Gated Sodium Channel Nav1.4 [PDF]
Toxins, 2016 Saxitoxin (STX) and its analogs are paralytic alkaloid neurotoxins that block the voltage-gated sodium channel pore (Nav), impeding passage of Na+ ions into the intracellular space, and thereby preventing the action potential in the peripheral nervous ...
