Aetiology of stemphylium blight on lentil in Canada
Bibliographic record
Abstract
Field isolates of Stemphylium spp. collected from lentil and nine other western Canadian crops were compared to the ex-type isolate of Stemphylium botryosum by morphology and by molecular phylogenetic analysis based on the internal transcribed spacer (ITS) and the glyceraldehyde-3-phosphate dehydrogenase gene regions. Sequence data of these genes for six other Stemphylium spp. obtained from GenBank were also included in the phylogenetic analysis. Morphology of colonies and morphometry of conidia agreed with previous descriptions of S. botryosum, but did not correlate with the clustering observed in the phylogenetic analysis. Sequence data revealed that S. botryosum is one of probably two Stemphylium spp. involved in the development of stemphylium blight on Canadian lentil, and is associated with other hosts such as faba bean, soybean, bean, pea, alfalfa, coriander, caraway and fenugreek. More than one validly described Stemphylium sp. was associated with the second cluster of isolates causing stemphylium blight, indicating that an extensive taxonomic review of the genus Stemphylium is required before this second stemphylium blight pathogen can be identified by name.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
