Multiple protein phylogenies show that Oxyrrhis marina and Perkinsus marinus are early branches of the dinoflagellate lineage.
Oxyrrhis marina and Perkinsus marinus are two alveolate species of key taxonomic position with respect to the divergence of apicomplexans and dinoflagellates. New sequences from Oxyrrhis, Perkinsus and a number of dinoflagellates were added to datasets of small-subunit (SSU) rRNA, actin, alpha-tubulin and beta-tubulin sequences, as well as to a combined dataset of all three protein-coding genes...

متن کاملThe protozoa dinoflagellate Oxyrrhis marina contains selenoproteins and the relevant translation apparatus.
In the phylogenetic tree, selenoproteins and the corresponding translation machinery are found in Archaea, Eubacteria, and animals, but not in fungi and higher plants. As very little is known about Protozoa, we searched for the presence of selenoproteins in the primitive dinoflagellate Oxyrrhis marina, belonging to the Protoctista kingdom. Four selenoproteins could be obtained from O. marina ce...
متن کاملBiology of the Marine Heterotrophic Dinoflagellate Oxyrrhis marina: Current Status and Future Directions
Heterotrophic dinoflagellates are prevalent protists in marine environments, which play an important role in the carbon cycling and energy flow in the marine planktonic community. Oxyrrhismarina (Dinophyceae), a widespread heterotrophic dinoflagellate, is a model species used for a broad range of ecological, biogeographic, and evolutionary studies. Despite the increasing research effort on this...
متن کاملThe highly reduced and fragmented mitochondrial genome of the early-branching dinoflagellate Oxyrrhis marina shares characteristics with both apicomplexan and dinoflagellate mitochondrial genomes.
The mitochondrial genome and the expression of the genes within it have evolved to be highly unusual in several lineages. Within alveolates, apicomplexans and dinoflagellates share the most reduced mitochondrial gene content on record, but differ from one another in organisation and function. To clarify how these characteristics originated, we examined mitochondrial genome form and expression i...
