Integrase diversity and transcription of the maize retrotransposon<i>Grande</i>
Bibliographic record
Abstract
Grande is an abundant gypsy-like retrotransposon present in the genera Zea and Tripsacum. Related retro transposon families can be found in sorghum, rice, and barley, but not in wheat or rye. We have amplified and sequenced several copies of part of the integrase domain derived from the Zea mays, Zea diploperennis, and Tripsacum dactyloides genomes. There are no significant differences in divergence or clustering between the integrase sequences of these species. The substitution rate for synonimous sites was found to be higher than those of non-synomymous sites; this indicates that Grande integrase has been under purifying selection for function. Grande is transcribed in leaves. The transcripts show sequence diversity similar to that of genomic sequences, but belong to restricted clades; this indicates that only some evolutionary branches of Grande have retained transcriptional competence.

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.
