A rapid method for assessing the viability of fungal spores<sup>1</sup>
Bibliographic record
Abstract
The LIVE/DEAD® BacLight™ Bacterial Viability Kit (L-7007) manufactured by Molecular Probes, Inc. (Eugene, Oregon, U.S.A.), which provides a two-colour fluorescence assay of bacterial viability, was useful for determining the viability of the hyaline spores of Colletotrichum gloeosporioides f. sp. malvae, Leptosphaeria maculans, and Sclerotinia sclerotiorum and the thick-walled spores of Alternaria brassicae. Under blue light, viable spores fluoresced green and dead spores fluoresced red. Cells of multicellular spores fluoresced green or red according to their viability. In tests performed with S. sclerotiorum, there was no significant difference between viability as determined with the kit and in vitro germinability. With C. gloeosporioides, the proportion of spores that germinated in vitro was lower than the proportion of viable spores, indicating that not all viable spores could germinate.Key words: blackleg, black spot, two-colour fluorescence assay.
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.
