Comparative analysis of mitochondrial genomes of <i>Chaetoceros</i> species
Bibliographic record
Abstract
Chaetoceros is one of the most diverse genera of marine planktonic diatoms. Chaetoceros species are common and may become dominant in coastal ecosystems. Many Chaetoceros species can develop harmful algal blooms with negative effects on the aquaculture industry. In this study, we constructed full-length mitochondrial genomes (mtDNAs) for 12 Chaetoceros species, including eight known species and four undescribed species. The sizes of these mtDNAs are generally similar, varying from 34,174 to 39,411 bp. Despite extensive synteny conservation, discrete regions showed high variations, and based on these regions, a specific primer chaetomt1 for Chaetoceros species was designed. The availability of mtDNAs from various Chaetoceros species is not only valuable as a super-barcode for phylogenetic analysis but also important for functional and evolutionary analysis of diatoms.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
