Abstract

fetched live from OpenAlex

Surveys of commercial and seed potato fields for virus diseases (1998 to 2002) in Manitoba established that Potato virus Y (PVY) is of concern in seed potato production. To determine the prevalence of PVY strains, PVY-infected tubers identified by reverse transcription-polymerase chain reaction (RT-PCR) from surveys (2000 to 2001) were grown for symptom expression and strain characterization by strain-specific RT-PCR, bioassays, and serological assays. Of the samples collected (2000 to 2001) and tested by RT-PCR, 4.0% contained PVY. Further analysis of the PVY-positive samples by a duplex RT-PCR facilitating the simultaneous detection of common (PVY O ) and tobacco veinal necrosis strains (PVY N/NTN ) indicated that 37.5% contained PVY O and 63.5% contained PVY N -type isolates. Analysis of the PVY N -type samples using three monoclonal antibodies (MAbs) showed that all reacted with only the PVY O MAbs and not with the PVY N -specific MAb. Partial nucleotide sequences of both ends of PVY-RNA showed that the PVY N -type isolates resembled those reported in 1996 from Manitoba. These isolates are designated as PVY N:O . In view of the increased incidence of PVY N:O in one production area, seed tubers imported from other provinces of Canada and the neighboring United States were analyzed for PVY N:O . The PVY N:O was detected in imported seeds from Minnesota, Montana, and North Dakota.

Not 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.
