Analysis of intragenic recombination at<i>wx</i>in rice: Correlation between the molecular and genetic maps within the locus
Bibliographic record
Abstract
In plant genomes as well as other eukaryotic genomes, meiotic recombination does not occur uniformly. At the level of the gene, high recombination frequencies are often observed within genetic loci in maize, but this feature of intragenic recombination is not seen at the csr1 locus in Arabidopsis. These observations suggest that meiotic recombination in plant genomes varies considerably among species. In the present study we investigated meiotic recombination at the wx locus in rice. The mutation sites of wx mutants induced by ethyl methanesulfonate (EMS) treatment or gamma-ray irradiation and a spontaneous wx mutant were physically characterized, and the genetic distances between those wx mutation sites were estimated by pollen analysis. Based on these results, the recombination frequency at the wx locus in rice was estimated as 27.3 kb/cM, which was about 10 times higher than the average for the genome, suggesting that there was a radically different rate of meiotic recombination for intra- and intergenic regions in the rice genome.

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.
