Journal ArticleDOI
Morphological and molecular characterization of three new Azadinium species (Amphidomataceae, dinophyceae) from the Irminger sea.
TL;DR: Molecular phylogenetics as inferred from concatenated SSU rRNA, ITS, and LSU rRNA sequence data supported the distinctiveness of the three new species of Azadinium, and none of the new species produced any known AZAs in measurable amounts.
Journal ArticleDOI
Genetic diversity of the harmful family Kareniaceae (Gymnodiniales, Dinophyceae) in France, with the description of Karlodinium gentienii sp. nov.: A new potentially toxic dinoflagellate
Elisabeth Nézan,Raffaele Siano,Sylviane Boulben,Christophe Six,Gwenael Bilien,Karine Chèze,Audrey Duval,Sophie Le Panse,Julien Quere,Nicolas Chomérat +9 more
TL;DR: The results of the analyses corroborate the genetic results in favour of the erection of Karlodinium gentienii sp.
Journal ArticleDOI
Novel Widespread Marine Oomycetes Parasitising Diatoms, Including the Toxic Genus Pseudo-nitzschia: Genetic, Morphological, and Ecological Characterisation
Andrea Garvetto,Elisabeth Nézan,Yacine Badis,Gwenael Bilien,Paola Arce,Eileen Bresnan,Claire M. M. Gachon,Raffaele Siano +7 more
TL;DR: Using single-cell techniques, morphologically and molecularly, intracellular parasitoids infecting four potentially toxin-producing Pseudo-nitzschia and one Melosira species on the North Atlantic coast are characterise and called for investigation of their phenology, evolution, and potential contribution in controlling their host spatial-temporal dynamics.
Journal ArticleDOI
Ostreopsis lenticularis Y. Fukuyo (Dinophyceae, Gonyaulacales) from French Polynesia (South Pacific Ocean): A revisit of its morphology, molecular phylogeny and toxicity.
Nicolas Chomérat,Gwenael Bilien,Amélie Derrien,Kévin Henry,André Ung,Jérôme Viallon,Hélène Taiana Darius,Clémence Mahana Iti Gatti,Mélanie Roué,Fabienne Hervé,Damien Réveillon,Zouher Amzil,Mireille Chinain +12 more
TL;DR: The present study aims at revisiting the morphology, molecular phylogeny and toxicity of O. lenticularis based on the analysis of 47 strains isolated from 4 distinct locales of French Polynesia, stressing the need to reconsider its current classification within the group of toxic species.
Journal ArticleDOI
Adding new pieces to the Azadinium (Dinophyceae) diversity and biogeography puzzle: Non-toxigenic Azadinium zhuanum sp. nov. from China, toxigenic A. poporum from the Mediterranean, and a non-toxigenic A. dalianense from the French Atlantic
Zhaohe Luo,Bernd Krock,Kenneth Neil Mertens,Elisabeth Nézan,Nicolas Chomérat,Gwenael Bilien,Urban Tillmann,Haifeng Gu +7 more
TL;DR: The present study supports the view of a high diversity and wide distribution of species belonging to Azadinium and suggests that this species may be responsible for azaspiracid contaminations in shellfish from the Mediterranean Sea.
