Development and linkage mapping of E-STS and RGA markers for functional gene homologues in apple
Bibliographic record
Abstract
Linkage maps developed from known-function genes can be valuable in the candidate gene mapping approach. A set of 121 expressed sequence tagged site (E-STS) primer pairs were tested on a framework genetic linkage map of apple (Malus x domestica Borkh.) constructed using simple sequence repeats (SSRs) and randomly amplified polymorphic DNA (RAPD) markers. These known-function gene markers, E-STSs, were supplemented by markers for resistance gene analogues (RGAs), designed based on conserved motifs in all characterized resistance genes isolated from plant species. A total of 229 markers, including 46 apple E-STSs, 8 RGAs, 85 SSRs from apple and peach, and 88 RAPDs, were assigned to 17 linkage groups covering 832 cM of the apple genome, based on 52 individuals originating from the cross 'Antonovka debnicka' (Q12-4) x 'Summerred'. Clusters of E-STS and RGA loci were located in linkage groups previously identified to carry resistance genes, some of which confer resistance to apple scab disease caused by Venturia inaequalis (Cke.) Wint.

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.
