Viruses Associated with Rusty Mottle and Twisted Leaf Diseases of Sweet Cherry Are Distinct Species
Bibliographic record
Abstract
Virus RNA sequences related to those of the family Betaflexiviridae were amplified from trees affected with the following diseases: cherry twisted leaf, apricot ring pox, cherry necrotic rusty mottle, cherry rusty mottle, and cherry green ring mottle. Phylogenetic analysis of virus sequences obtained from these diseased trees from western North America, along with published sequences of Cherry green ring mottle virus (CGRMV) and Cherry necrotic rusty mottle virus (CNRMV), revealed four major clades. Segregation into these four populations correlated with distinct symptom expression on woody indicators, suggesting that each clade represents a distinct virus species within the family Betaflexiviridae. The viruses occupying each clade were designated clade I: Cherry twisted leaf associated virus, clade II: CNRMV, clade III: Cherry rusty mottle associated virus, and clade IV: CGRMV. Potential recombination events were predicted to occur within and between these viruses, the latter being strongly supported by incongruent phylogenies. Examination of frequency distribution data derived from pairwise sequence comparisons of coat protein coding sequences resulted in a proposal for alternative guidelines for species demarcation for this family of viruses.

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.
