Purification and Characterization of Stagonospora nodorum Toxins and Mapping of Toxin Insensitivity
Bibliographic record
Abstract
Stagonospora nodorum is a pathogenic fungus of wheat causing Stagonospora nodorum blotch disease, an important disease in western Canada. S. nodorum produces a multitude of host selective toxins (HSTs), which when recognized by corresponding sensitivity gene in wheat results in a compatible interaction. In this study, novel HST-host sensitivity gene interactions were investigated. Two different putative HSTs were identified. SnTox3 was likely one of the HSTs present in S. nodorum isolate Swift Current culture filtrate as the chromosomal location of the compatible sensitivity gene corresponded to that of Snn3 locus. Another putative HST interacting with Tsn1 or a tightly linked sensitivity gene was identified from S. nodorum isolate Langham. SNOG_15679, a candidate gene for production of this putative HST was heterologously expressed in Pichia pastoris which caused chlorosis on a sensitive host. Additional tests will be required to confirm the bioactivity of putative novel HST(s) produced by isolate Langham.

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.
