Abstract
A reverse transcription loop-mediated isothermal amplification of DNA (RT-LAMP) for detection of Potato virus Y (PVY) was developed. In this procedure, a set of four primers matching a total of six sequences of the coat protein (CP) gene of PVY were designed in such a way that a loop could be formed and elongated during DNA amplification. Using PVY CP complementary DNA clones as templates, the LAMP reaction was optimized by adjusting the concentrations of MgSO 4 , dNTPs, and Bst DNA polymerase. The effects of fragment length of target DNA on LAMP also were investigated. Two-step and one-step RT-LAMPs were performed using RNA extracts of various PVY cultures, and the results were correlated with two-step reverse transcription polymerase chain reaction (RT-PCR) for detection of PVY. Further, the turbidity caused by precipitation of magnesium pyrophosphate formed in positive RT-LAMP reactions was used to measure the amplification by utilizing a time-saving spectrophotometric method. The one-step RT-LAMP-turbidity method gave results comparable with the two-step RT-PCR method for detection of PVY from potato leaf and tuber samples. Of the total 240 samples, 234 were diagnosed similarly by both methods.

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 it
