Contributions of Oxyrrhis marina to molecular biology, genomics and organelle evolution of dinoflagellates
Bibliographic record
Abstract
The flagellate Oxyrrhis marina has been the subject of numerous studies addressing diverse aspects of protist biology including feeding, motility, ecology and cell biology. In spite of the rich body of information that has been built around this organism, the molecular biology of O. marina has remained virtually unstudied until very recently. Studying the molecular biology and genomics of O. marina is not only important due to its role as a model organism and practical accessibility; current evidence shows that it occupies a basal position within the dinoflagellate lineage, making it an ideal starting point to reconstruct the evolution of several interesting characters in this diverse group and its sister group Apicomplexa. Among these features, dinoflagellates have very divergent mitochondrial genomes, a complex history of plastid evolution and unique features involving the nuclear genome and transcription. Here we review and discuss how recent findings from O. marina are contributing to shed light on these and other aspects of the evolutionary history of two important eukaryotic lineages, the apicomplexans and dinoflagellates.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
