Resistance genes for rye stem rust (<i>SrR</i>) and barley powdery mildew (<i>Mla</i>) are located in syntenic regions on short arm of chromosome
Bibliographic record
Abstract
Genetic stocks were developed for the localization and eventual cloning of the stem rust resistance gene SrR that occurs in wheat lines carrying the 1RS translocation from Secale cereale 'Imperial' rye. We have used a mutation-based approach for molecular analysis of the SrR region in rye. Forty-one independent mutants resulting in loss of SrR resistance were isolated: many of these were deletions of various sizes that were used to locate SrR with respect to chromosome group 1S markers. The analysis of the mutants showed that markers about 1 Mb apart flanking the barley Mla locus also flank SrR. Additionally, three of the approximately 20 closely related sequences of Mla in rye are deleted in each of six interstitial deletion mutants of SrR. The results indicate that the SrR region in rye is syntenic to the Mla region in barley or that SrR is possibly orthologous to the Mla locus.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
