Phenotypic, ITS phylogenetic and pathogenic analyses of Pyllosticta Multicorniculata associated with needle blight symptoms of balsam fir in Canada
Bibliographic record
Abstract
Phyllosticta multicorniculata Bissett & Palm causes needle blight on Abies balsamea (L) Mill. in eastern Canada. The disease symptoms are similar to those provoked by Phyllosticta abietis Bissett & Palm on Abies grandis Lindl. in the U.S.A. Preliminary study based on rDNA ITS sequence data analysis, revealed that P. multicorniculata formed distinct but closely-related clade with other sister mitosporic Phyllosticta and teleomorphic Guignardia and Botryosphaeria taxa. However, the phylogenetic position of the fungus is still doubtful which demand further and more advanced molecular investigation. This is the first report of a microconidial stage in P. multicorniculata and, for the first time, description of the developing mucilaginous appendages in macroconidia. This study contributes in disease diagnostics and gives new information on distribution of the disease in Canada.

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.
