di·no·flag·el·late

(dī'nō-flaj'ĕ-lāt),
A plantlike flagellate of the subclass Phytomastigophorea, some species of which (for example, Karenia brevis) produce a potent neurotoxin that may cause severe food intoxication following ingestion of parasitized shellfish.
[G. dinos, whirling, + L. flagellum, a whip]

dinoflagellate

(dī′nō-flăj′ə-lĭt, -lāt′, -flə-jĕl′ĭt)
n.
Any of numerous minute, chiefly marine protists of the phylum Dinoflagellata, characteristically having two flagella and a cellulose covering and forming one of the chief constituents of plankton. They include bioluminescent species, photosynthetic species, and species that produce red tide.

dinoflagellate

any of a group of unicellular biflagellate aquatic organisms forming a constitutent of plankton now normally placed in the division Pyrrhophyta. They can be regarded as an order of protozoans (Dinoflagellata) or a class of algae (Dinophyceae).

Considering the photophysiology of the symbiotic dinoflagellates, an opposing explanation of mechanisms for glucose and glycerol release/translocation by the symbionts canbe presentlyinferred: (1) glucose production by the symbiont may be subj ect to feedback inhibition by photosynthesis [23] and would not allow glucose to represent an important overflow mechanism.
Perez and Weis [28] suggested that CYP may help in the regulation of symbiosis between the sea anemone Aiptasia pallida and intracellular dinoflagellates. Interestingly, their study showed that the dinoflagellate symbionts (zooxanthellae) became heat sensitive when CYP was inhibited by cyclosporine and showed loss of the symbionts from the host tissues [28].
