The type species (holotype) of the genus Dinophysis is Dinophysis acuta Ehrenberg. Status of name. This name is of an entity that is currently accepted

Photo taken during the National Center for Marine Algae and Microbiota Harmful Algae Taxonomy Course at Bigelow Laboratory in 2019 (A. Pappas, 2019). Dinophysis. Dinophysis spp.: This is a coastal ocean dinoflagellate that can contain little to no pigments. Dinophysis produces okadaic acid as well as other toxins that lead to diarrhetic shellfish poisoning, DSP. Primarily blooms subsurface in thin layers. Dinophysis fortii is a photosynthetic dinoflagellate.

… Harmful algal blooms of Dinophysis have recently emerged as a human health threat in the U.S., resulting in closures of shellfish harvesting to prevent Diarrhetic Shellfish Poisoning. We are working to identify the drivers (stimuli) of Dinophysis success in four regions with important shellfisheries (Texas, Washington, New York, and Virginia), and to create a baseline Dinophysis and Phalacroma species containing diarrheic shellfish toxins and pectenotoxins occur in coastal temperate waters all year round and prevent the harvesting of mussels during several months each year in regions in Europe, Chile, Japan, and New Zealand. Toxicity varies among morphologically similar species, and a precise identification is needed for early warning systems. Dinophysis spp. are a major source of diarrheic toxins to marine food webs, especially during blooms. This study documented the occurrence, in late May 2016, of a massive toxic bloom of the Dinophysis acuminata complex along the southern coast of Brazil, associated with an … The toxic dinoflagellate alga Dinophysis threatens human health and coastal economies through the production of toxins which cause diarrhetic shellfish poisoning (DSP) in humans. Although North American waters have historically been free of Dinophysis blooms and associated DSP poisoning events, Dinophysis species can be a common component of marine phytoplankton.

and their toxins on every US coast in recent years, the need to identify and monitor for problematic Dinophysis populations has become apparent. Here, we present morphological analyses, using light and scanning electron microscopy, and rDNA sequence analysis, using a ~2‐kb sequence of ribosomal ITS1, 5.8S, ITS2, and LSU DNA, of Dinophysis Dinophysis sacculus and Alexandrium sp. occurred, in 1993, in shallow inland waters (a brackish lagoon of the Tyrrhenian Sea), characterized by thermo-haline homogeneity.

Dinophysis spp. digest the prey nuclei and all other cell organelles upon ingestion (except the kleptochloroplasts) and they are therefore believed to constantly acquire new chloroplasts as the

Want to see an alphabetical list of ALL species within this taxa group? After suspicion of Dinophysis as the organism source, PTX-2 was identified in Dinophysis fortii and appears to be the most common PTX, with a brut formula of C 47 H 70 O 14 (Draisci et al., 1996; Lee et al., 1989). Surprisingly, PTX-2 was also identified in a two-sponge association (Jung et al., 1995). Dinophysis rotundata has been associated with toxicity only in one case, in the Black Sea (Vershnin & Kamnev 2001). However, since D. caudata was also present in the same sample, the species responsible for DSP cannot be ascertained.

Division The dinoflagellate Dinophysis is an ideal model organism for the study of HGT and plastid evolution in eukaryotes. The genus is exceptional among dinoflagellates, possessing plastids derived from cryptophyte algae. Dinophysis can be maintained in pure culture for several months but is ultimately mixotrophic and needs to feed to acquire plastids (a process known as kleptoplastidy). Dinophysis.
