Abstract
In recent years, the number of plant hosts affected by peanut witches’-broom group (16SrII) phytoplasma in Saudi Arabia has increased at a concerning speed. Since 2015 symptoms resembling phytoplasma-related diseases have been reported in Al-Qassim region affecting the wild plants globe amaranth, amaranthus, black nightshade, and buckthorn. Except for globe amaranth, which showed flower deformations, the other plants showed witches’ broom and little leaves. All the symptomatic samples collected in this study were positive for phytoplasma using universal primers targeting the 16S rRNA-encoding gene. Sequence analysis identified the phytoplasma as a member of the 16SrII-X subgroup, originally described in Saudi Arabia by our group. This is the first report of globe amaranth, amaranthus, black nightshade, and buckthorn as phytoplasma hosts in Saudi Arabia, and the first report worldwide of globe amaranth as a phytoplasma host and buckthorn being affected by 16SrII phytoplasma group.

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
