Fish and Wildlife Scrvicc, Galveston, Texas ABSTRACT Laboratory expcrimcnts wcrc conducted to dctcrmine the effects of in u&o cultures of the mnrinc dinoflagellate, Gonynulax monilntn Ilowcll, on fishes. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Gonyaulax spinifera is a species of dinoflagellates in the family Gonyaulacaceae. Liquid chromatography–high-resolution mass spectrometry (LC-HRMS) analysis of a Namibian strain of Gonyaulax spinifera showed the presence of a number of yessotoxins (YTXs). The species Gonyaulax spinifera and Lingulodinium polye-drum, which may also produce YTX, have been identified in certain European and American countries (4,7-11). Photo courtesy of TDWP .

Reviewers, Librarians Introduction . Purified 24-hydroxyYTX was quantitated by NMR, and its relative toxicity evaluated using two embryonic zebrafish toxicity assays. Depth. Determination of the toxin content of natural samples (mussels and net haul plankton samples) as well as monitoring of the dinoflagellate species present in seawaters allowed us to correlate the presence of G. spinifera to that of homoYTX in mussels. Liquid chromatography–high-resolution mass spectrometry (LC-HRMS) analysis of a Namibian strain of Gonyaulax spinifera showed the presence of a number of yessotoxins (YTXs). These metrics are regularly updated to reflect usage leading up to the last few days. Gonyaulax spinifera. Information about how to use the RightsLink permission system can be found at Two G. spinifera isolates, sampled in different years, were analyzed and resulted to be different in both toxin content and gene sequence: the isolate sampled in 2005 produced only low levels of YTX (5.4 pg cell−1) while that sampled in 2006 contained higher toxin amounts, namely 33.4 pg cell−1 of homoYTX and 3.6 pg cell−1 of YTX; the two isolates also differed in 111 and 176 nucleotide positions, respectively, in the SSU and partial LSU rDNA genes. 0.000 ~ 150.000 m Record acquisition … Gonyaulax spinifera (Claparede & Lachmann) Diesing, 1866 synonym: UKSI Classification unranked Biota kingdom Chromista phylum Myzozoa class Dinophyceae order Gonyaulacales family Gonyaulacaceae genus Gonyaulax species Gonyaulax spinifera. nov It is notable that the 28S rDNA sequences from the strains called G. spinifera GSA0602 from the Adriatic Sea (Accession number: EU805591 ) by Riccardi et al.

In autumn 2002, parasitic dinoflagellates of the genus Amoebophrya Koeppen infected populations of the bloom‐forming thecate dinoflagellates Alexandrium affine (Inoue and Fukuyo) Balech and Gonyaulax spinifera (Claparede and Lachmann) Diesing in coastal waters of Korea. not otherwise permitted to reproduce, republish, redistribute, or sell any Supporting Information The north-western coasts of the Adriatic sea have long been subjected to recurring cases of harmful algae blooms and concomitant mussel contamination. 24-HydroxyYTX demonstrated reduced toxicity compared to YTX.

Comparing similar sequences of G. spinifera strains contained in GenBank, divergences among the Adriatic strains and strains of different geographical origin emerged; on the contrary, a good similarity was evidenced (1.3%) between the Adriatic isolate sampled in 2006 and two New Zealand strains; the similarity was confirmed also by the presence in all strains of YTXs, although the New Zealand strains were analyzed by ELISA which could not distinguish among the different YTX analogues.

In relation to Gonyaulax spinifera, homo-YTX seems to be the main toxin produced by this species. However, although the taxonomy of the species complex G. spinifera remains largely unresolved, this study allowed to unambiguously link the presence of G. spinifera to recurring mussel toxicity episodes.

Due to an originally confusing description of the species and to the availability of very low number of deposited sequences the doubt arises whether the studied G. spinifera strains belong to the same species. Culturing the G. spinifera strain afforded sufficient biomass for purification of the new analogue through a series of solvent partitioning and chromatographic steps, yielding ∼0.9 mg as a solid.

Gonyaulax spinifera, previously considered a non-YTX producer, was isolated from the seawater samples and production of YTX by the cells grown in culture was determined by identification of YTXs by ELISA. Since then, farmed molluscs are yearly found to contain YTXs for long periods with a severe impact on aquaculture activities. Results indicate that the organism produced a substance (s) toxic to fishes and that the toxicity of the medium is increased if the dinoflagellate cytolyses. Occurrence records.

Recently, ELISA analyses on single cells indicated Gonyaulax spinifera (Claparède et Lachmann) Diesing 1866 from New Zealand as a YTX producer (Rhodes et al., 2006), thus correlating for the first time the occurrence of such microalga in seawater to mussel toxicity. The Supporting Information is available free of charge on the ACS Publications website at DOI: 10.1021/acs.jnatprod.9b00318. Principal among these were YTX (1), homoYTX (2), and a tentative hydroxylated analogue that did not correspond to any previously confirmed YTX structures. By continuing you agree to the use of cookies. These instances are called algal blooms. In 1995, yessotoxins (YTXs) were detected for the first time in Adriatic mussels and their presence was subsequently linked to the presence of Protoceratium reticulatum and occasionally Lingulodinium polyedrum in seawater. Mangin, 1922. Citations are the number of other articles citing this article, calculated by Crossref and updated daily. Cultures of G. spinifera were set up which gave us the opportunity to investigate toxin content and profile of the dinoflagellate, for the first time, by liquid chromatography–mass spectrometry (LC–MS) and to perform a molecular characterization of the species through rDNA sequencing. Laboratory experiments were conducted to determine the effects of in vitro cultures of the marine dinoflagellate, Gonyaulax monilata Howell, on fishes. The American Chemical Society holds a copyright ownership interest in any copyrightable Supporting In 2004, unusually high amounts of homoYTXs were detected in mussels. YTX production within and among dinoflagellate species tested to date is highly variable. It is native to Rio Grande do Norte, Santa Catarina, Pará, Rio de Janeiro, and Rio Grande do Sul.
