Mesodinium rubrum (original) (raw)
Mesodinium rubrum (or Myrionecta rubra) is a species of ciliates. It constitutes a plankton community and is found throughout the year, most abundantly in spring and fall, in coastal areas. Although discovered in 1908, its scientific importance came into light in the late 1960s when it attracted scientists by the recurrent red colouration it caused by forming massive blooms, that cause red tides in the oceans. In 2009, a new species of Gram-negative bacteria called Maritalea myrionectae was discovered from a cell culture of M. rubrum.

| dbo:abstract | Mesodinium rubrum (or Myrionecta rubra) is a species of ciliates. It constitutes a plankton community and is found throughout the year, most abundantly in spring and fall, in coastal areas. Although discovered in 1908, its scientific importance came into light in the late 1960s when it attracted scientists by the recurrent red colouration it caused by forming massive blooms, that cause red tides in the oceans. Unlike typical protozoans, M. rubrum can make its own nutrition by photosynthesis. The unusual autotrophic property was discovered in 2006 when genetic sequencing revealed that the photosynthesising organelles, plastids, were derived from the principal food of the ciliate, the photosynthetic algae called cryptomonads (or cryptophytes). It is, thus, both autotrophic and heterotrophic. This nature also indicates that it is an example of endosymbiosis, supporting the endosymbiotic theory, as well as the concept of stealing of cell organelles called kleptoplastidy. Moreover, M. rubrum represents additional endosymbiosis by transferring its plastids to its predators, the dinoflagellate planktons belonging to the genus Dinophysis. In 2009, a new species of Gram-negative bacteria called Maritalea myrionectae was discovered from a cell culture of M. rubrum. (en) Myrionecta rubra или Mesodinium rubrum — вид инфузорий, входящих в состав планктона. Форма яйцевидная, передний конец больше заднего. Диапазон размеров широкий (10-100 мкм), средняя длина 20-60 мкм. Крупные формы более асимметричны. Плавает быстрыми рывками (10—20× длины), замирая на 1—10 с. Данный вид, как и многие другие виды планктонных инфузорий, способен к фотоавтотрофному питанию за счет симбиоза с водорослями. Ранее считалось, что Myrionecta rubra имеет постоянных эндосимбионтов — криптофитовых водорослей. В 2000 г было показано, что эта инфузория содержит хлоропласты криптофитовых, которых она поглощает в качестве пищи (несмотря на отсутствие постоянного цитостома и цитофаринкса). Видимо, способна также к питанию бактериями. Может вызывать цветение воды (нетоксичный красный прилив) в прибрежных участках морей и эстуариях. (ru) |
