Abstract
Strawberry mild yellow edge virus (SMYEV) was detected in 116 samples out of 423 collected from strawberry plants grown in commercial and experimental plantations in seven provinces of Poland. The number of samples infected with strawberry mottle virus (SMoV) accounted for 84.6% of the 26 SMYEV-positive samples selected for sequence analysis. The nucleotide sequence similarity of the coat protein (CP) gene of 26 selected SMYEV isolates ranged from 84.8% to 100%, and 81.4–99.5% identity was found between these isolates and 48 SMYEV strains from different countries. The CP region's phylogenetic analysis showed that most isolates from Poland clustered within group I (type D74). In contrast, Talis and 3233CL isolates represented group III (type MY18), and the San isolate was clustered in group V (type ABY1-01). Recombination analysis of the CP gene sequences detected two possible recombination events. One was noticed in the Argentinian strain 53, which formed group III with isolates from Chile, and Polish isolates Talis and 3233CL. Another was identified in the Chinese strain sy02 sequence with evidence of the same recombination event in Canadian strains, and the Polish isolate San (V group). Leaf epinasty, mottling, and yellowing of the young leaves and dieback of the older leaves were observed on 'Alpine' and 'EMC' indicator plants grafted with leaves of strawberry plants co-infected with SMYEV and SMoV. A single infection with SMYEV induced milder symptoms based on these indicators.

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 it
