Importance of organism and transcriptomesAlexandrium fundyense is a photosynthetic dinoflagellate that produces potent neuromuscular toxn (saxitoxin), which is accumulated in shellfish causing mortality of sea birds and mammals, and health concerns in humans. Blooms of this organism, most common in Gulf of Maine, New Hampshire, and Long Island Sound, causes dramatic economic loss. A. fundyense has typical peridinin-containing plastid, and its photosynthesis contributes to CO2 removal from the atmosphere and its conversion to organic matter for growth of its own and animals. A. fundyense is also bioluminescent, under the control of a luciferase-luciferin-binding protein enzyme system. Evolutionarily, Alexandrium is thought to be the most recently emerging lineage in dinoflagellates, calling for the need of in-depth phylogenetic/phylogeneomic analysis to verify this phylogenetic position.
