Detection and Confirmation of <i>Potato mop-top virus</i> in Potatoes Produced in the United States and Canada
Bibliographic record
Abstract
Potato mop-top virus (PMTV) was detected in potatoes grown in the United States and Canada during surveillance testing by a reverse transcription-polymerase chain reaction (RT-PCR) targeting the coat protein gene in RNA3. Out of 3,221 lots of seed and ware potatoes that were tested, 4.3% were positive for PMTV. The reliability of the survey results was confirmed by reextraction of selected samples and additional RT-PCR tests using two primer sets targeting gene segments in RNA2 and RNA3. Amplicons generated from RNA2 and RNA3 were identified by analysis of fragment length polymorphisms after digestion with BamHI and HindIII, respectively. PMTV was further identified by enzyme-linked immunosorbent assay, bioassay on Nicotiana debneyi, and transmission electron microscopy. Sequencing of a portion of the coat protein gene revealed near 100% identity among isolates from the United States and Canada and >97% homology of the North American isolates with European isolates.

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.
