A genetic linkage map of<i>Pleurotus pulmonarius</i>based on AFLP markers, and localization of the gene region for the sporeless mutation
Bibliographic record
Abstract
In the cultivation of edible mushrooms, including Pleurotus pulmonarius (Fr.) Quel., the enormous number of spores produced by fruiting bodies can adversely affect mushroom growers' health, mushroom cultivation facilities, and the genetic diversity of natural populations. In this study, we constructed a primary genetic linkage map and identified the locus associated with the sporulation-deficient (sporeless) mutation of P. pulmonarius using 150 progeny isolates derived from a cross between sporeless and wild-type isolates. Based on the segregation of 300 AFLP markers, two mating-type factors, and the sporeless trait, a linkage map was generated consisting of 12 linkage groups. The map covered a total genetic distance of 971 cM, with an average marker interval of 5.2 cM. The gene region responsible for the sporeless mutation was located in linkage group II including 40 AFLP markers and the A mating-type factor locus. Of these markers, the nearest marker to the sporeless locus was located 1.4 cM away. Construction of this P. pulmonarius genetic linkage map and identification of markers that are closely linked to the sporeless locus will facilitate marker-assisted selective breeding of a sporeless strain with economically important traits.

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.
