Mitochondrial genome analysis of the predatory mite<i>Phytoseiulus persimilis</i>and a revisit of the<i>Metaseiulus occidentalis</i>mitochondrial genome
Bibliographic record
Abstract
In this study we sequenced and analysed the complete mitochondrial (mt) genome of the Chilean predatory mite Phytoseiulus persimilis Athias-Henriot (Chelicerata: Acari: Mesostigmata: Phytoseiidae: Amblyseiinae). The 16 199 bp genome (79.8% AT) contains the standard set of 13 protein-coding and 24 RNA genes. Compared with the ancestral arthropod mtDNA pattern, the gene order is extremely reshuffled (35 genes changed position) and represents a novel arrangement within the arthropods. This is probably related to the presence of several large noncoding regions in the genome. In contrast with the mt genome of the closely related species Metaseiulus occidentalis (Phytoseiidae: Typhlodrominae) - which was reported to be unusually large (24 961 bp), to lack nad6 and nad3 protein-coding genes, and to contain 22 tRNAs without T-arms - the genome of P. persimilis has all the features of a standard metazoan mt genome. Consequently, we performed additional experiments on the M. occidentalis mt genome. Our preliminary restriction digests and Southern hybridization data revealed that this genome is smaller than previously reported. In addition, we cloned nad3 in M. occidentalis and positioned this gene between nad4L and 12S-rRNA on the mt genome. Finally, we report that at least 15 of the 22 tRNAs in the M. occidentalis mt genome can be folded into canonical cloverleaf structures similar to their counterparts in P. persimilis.

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.
