The complete mitochondrial genome of Pleurocorallium inutile (Octocorallia: Scleralcyonacea: Coralliidae)
Bibliographic record
Abstract
BACKGROUND: Although the genus Pleurocorallium contains an economically valuable species, limited genetic information is available. Here, we report the complete mitochondrial genome sequence of Pleurocorallium inutile. In Japan, this species is known as damesango, meaning "useless coral", because it has no commercial value when caught as a bycatch during precious coral harvesting. Although several species of Pleurocorallium can be distinguished morphologically, some cannot be differentiated using the limited number of characterized genetic regions, such as eight mitochondrial and elongation factor genes. P. inutile is one such species, and therefore, analyzing its complete mitochondrial genome will be useful for identifying its phylogenetic status, distinguishing it from other commercially important species, and providing insights into the evolution of octocoral mitochondrial genes. METHODS AND RESULTS: The 18,822 bp mitochondrial genome of P. inutile consists of 14 protein-coding genes, two ribosomal RNA (rRNA) genes (rnL and rnS), and one tRNA gene (trnM). Consistent with previous studies, P. inutile shares the same gene arrangement as other Pleurocorallium species, while exhibiting distinct gene arrangements compared to closely related genera, such as Corallium and Hemicorallium. A phylogenetic tree based on protein-coding and rRNA genes from currently available Coralliidae species indicated that Pleurocorallium exhibited greater within-genus genetic distances than Corallium and Hemicorallium. CONCLUSIONS: Our study clearly distinguished P. inutile from other species using published mitochondrial genomes. This sequence information will be useful for accurate biodiversity assessments and understanding octocoral mitochondrial gene evolution in the future.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
