Identification of AFLP markers on the satellite region of chromosome 1BS in wheat
Bibliographic record
Abstract
The satellite region on the short arm of chromosome 1B in wheat (Triticum aestivum L., 2n = 6x = 42) carries many agronomically important genes; i.e., genes conferring fungal disease resistance, seed storage proteins, and fertility restoration. To find molecular markers located on the satellite region, we applied the fluorescent AFLP (amplified fragment length polymorphism) technique to aneuploids and deletion stocks of the cultivar T. aestivum 'Chinese Spring'. Out of 6017 fragments amplified with 80 primer combinations in normal 'Chinese Spring', 24 were assigned to 1BS. Twelve of them clustered within a small region of the satellite known to be rich in RFLP (restriction fragment length polymorphism) markers. AFLPs in 1BS and in the whole genome were calculated between 'Chinese Spring' and T. spelta var. duhamelianum. The polymorphism rates in the satellite region (58.3%) and in the 1BS arm (45.8%) were much higher than the average rate for the whole genome (10.7%). Seven of the 12 AFLP markers in the satellite region were revealed to be specific to 'Chinese Spring' and could potentially be useful for genetic mapping in a segregation population of 'Chinese Spring' x T. spelta.

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.
