Molecular analysis of the complete set of length mutations found in the plastomes of<i>TriticumAegilops</i>species
Bibliographic record
Abstract
Precise location and nature of each of 14 length mutations detected among chloroplast DNAs of Triticum-Aegilops species by RFLP analysis were determined at the nucleotide sequence level. Each mutation was compared with at least three non-mutated wild-type plastomes as standards. These 14 length mutations were classified into 4 duplications and 10 deletions. One duplication occurred in the small single-copy region close to the border of the inverted repeat, and the remaining 13 length mutations took place in the large single-copy region. All length mutations occurred in the intergenic regions, suggesting that these length mutations do not affect plastid gene expression. Saltatory replication was the cause of all duplications, whereas intramolecular recombination mediated by short direct repeats played a substantial role in the deletions. Recurrent occurrences of certain deletion events were found in some AT-rich regions, which constituted hot spots for deletion. Out of four hypervariable regions detected among the grass plastomes, two (downstream of rbcL and a tRNA gene accumulated region) were still active after differentiation of Triticum and Aegilops complex.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
