The use of test tube plantlets for the assessment of Potato virus Y transmission by Myzus persicae and Aphis glycines
Bibliographic record
Abstract
Test tube plantlets were used to assess the transmission efficiency of Potato virus Y (PVY) from and to potato plants by the potato colonizing species green peach aphid ( Myzus persicae ) and the non-potato colonizing species soybean aphid ( Aphis glycines ). Similar levels of transmission of PVY by M. persicae were observed in the test tube plantlets and potted plants, demonstrating the reliability of this test for PVY transmission efficiency assay for aphids. The assay was then used to assess the transmission of PVY O and PVY N:O by M. persicae and A. glycines with two virus acquisition regimes, one with 5-min continuous probing and the other with 1-h acquisition access. The M. persicae mediated-transmission rate was 24.1% and 51.7% for PVY O and PVY N:O , respectively, under the 5-min acquisition regime; under the same acquisition regime, A. glycines led to 0.0% and 1.7% infection rates for PVY O and PVY N:O , respectively. Under the 1-h acquisition regime, no infection was observed except for PVY N:O by M. persicae , which exhibited an infection rate of 3.4%.

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.
