A DNA mismatch repair gene links to the<i>Ph2</i>locus in wheat
Bibliographic record
Abstract
DNA mismatch repair is an essential system for maintaining genetic stability in bacteria and higher eukaryotes. Based on the conserved regions of the bacterial MutS gene and its homologues in yeast and human, a wheat cDNA homologue of MSH6, designated TaMSH7, was isolated by RT-PCR. The deduced amino acid sequence of TaMSH7 shows conserved domains characteristic of other MSH6 genes, with highest similarity to maize MSH7 and Arabidopsis MSH7. TaMSH7 is expressed in meristem tissue associated with a high level of mitotic and meiotic activity, with maximum expression in the reproductive organs of young flower spikes. TaMSH7 is located on the short arms of chromosomes 3A, 3B, and 3D and has been mapped within barley chromosome 3HS. The copy on 3DS is located within the region deleted in the wheat mutant ph2a, which shows altered recombination frequency in the interspecific hybrids. The relationship between the ph2a mutant and TaMSH7 gene function is discussed.

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; both teacher heads agree on what is shown here.
