Multigene characterization of a ‘<i>Candidatus</i> Phytoplasma australasia’ strain associated with <i>Roystonea regia</i> in Oman
Bibliographic record
Abstract
Florida or Cuban royal palm (Roystonea regia (Kunth) O.F. Cook) is an important ornamental plant with many uses for humans. Royal palm trees grown in Muscat, Oman, were found exhibiting leaf yellowing, leaf decay starting on the mature leaves, and leaf stunting. Trunk tissue samples were collected and analysed with nested and semi-nested PCR assays for the 16S rRNA, translation elongation factor Tu (tuf), and immunodominant membrane protein (imp) genes, in order to characterize the phytoplasma associated with the affected trees. Sequence and phylogenetic analysis of the 16S rRNA, tuf, and imp genes indicated that the phytoplasma strains detected in the trees were identical and belonged to the 16SrII-D subgroup. This is the first report of an association between ‘Candidatus Phytoplasma asutralasia’-related strain and R. regia.

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.
