The ultrastructure of the dinoflagellate Ostreopsis cf. ovata Fukuyo, 1981 (Dinophyceae) from the Sea of Japan Zhirmunsky Institute of Marine Biology, Far East Branch, Russian Academy of Sciences, Vladivostok 690041 E-mail: The results of the ultrastructural study of dinoflagellates from the seas of Russia are presented in the example of Ostreopsis cf. ovata for the first time. The basic cell components (nucleus, chloroplasts, mitochondria, amphiesma, Golgi complex, and accumulative bodies) are described. An expanded and updated description of the chloroplasts and accumulative bodies is given. Crystalline aggregates characteristic of hypnozygotic cysts were found in species of the genus Ostreopsis for the first time. The data are compared with the results of ultrastructural studies on Ostreopsis cf. ovata that inhabits the Adriatic and the Caribbean seas and the coastal waters of Jeju Island (South Korea). New features of the structure of some organelles in Ostreopsis cf. ovata from Russian waters were revealed. Key words: dinoflagellates, Ostreopsis, ultrastructure. |
