Occurrence of a ‘ <i>Candidatus</i> Phytoplasma pruni’-Related Strain Associated with Commercial Poinsettias in Turkey
Bibliographic record
Abstract
Abstract The poinsettia ( Euphorbia pulcherrima Willd. ex Klotzsch.) is one of Turkey’s most important potted ornamental crops. Potted poinsettia plants exhibiting smaller-sized brilliant red bracts against the green leaves with free-branching were collected from commercial florists in three provinces of Turkey. In iPhyClassifier analysis, the query 16SrDNA sequences of our isolates shared 99.58% identity with that of the Candidatus Phytoplasma pruni. Our leaf samples consistently yielded a product of 0.7 kb by PCR with primers (KFD4F/KFD4R), which was newly designed based on X-Disease group (16SrIII) of phytoplasma secY sequences available in GenBank. The partial 16S rRNA sequences were used for phylogenetic analyses covering 41 taxa from the group of 16SrIII ’ Candidatus Phytoplasma’ strains, including 14 strains causing disease on poinsettia worldwide. The sequences that caused the same disease in poinsettia plants in Finland, the USA, Mexico, Taiwan, Japan, Korea, and Canada, including three strains from Turkey, formed a mono-phylogenetic group with a support value of 87%.

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.
