Caratterizzazione molecolare di ‘Candidatus Phytoplasma asteris’ in ortensia in Canada
Bibliographic record
Abstract
Hydrangea species are infected by phytoplasmas belonging to subgroups 16SrI-A and\n16SrI-B (aster yellows) inducing phyllody and virescence worldwide. In Japan some of\nthe phytoplasma associated such disease were classified as ‘Candidatus Phytoplasma\njaponicum’, moreover 16SrXII-A phytoplasmas were identified in Bulgaria and\nmore recently in Italy. The hydrangea phyllody disease was associated with 16SrI-B\nphytoplasmas in Canada, however no fine molecular characterization was carried\nout on the phytoplasmas in that country. Hydrangeas showing symptoms similar to\nthose associated with phytoplasma diseases were found and collected from landscape\nareas in South-western Ontario, Canada. Phytoplasmas belonging aster yellows group\nwere detected in all symptomatic samples tested by two different methodologies.\nDirect sequencing and sequence obtained after cloning of the 16Sr DNA gene show\nconfirmation of reported classification and the amplification and sequencing of groEL\ngene confirm previous classification in subgroup 16SrI-B and allow to enclose aster\nyellows phytoplasmas in hydrangeas from Canada in the groELI-III group that up to\nnow was only detected in Europe.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
