A sequence related to rice<i>Pong</i>transposable element displays transcriptional activation by in vitro culture and reveals somaclonal variations in maize
Bibliographic record
Abstract
Miniature inverted-repeat transposable elements (MITEs) are nonautonomous elements that are abundant in plant genomes. The rice MITE mPing was shown to be mobilized by anther culture, and the associated transposon Pong was shown to transpose actively in an Oryza sativa 'indica' rice cell-culture line. We have identified 3 sequences in maize named ZmTPAPong-like 1, 2, and 3 that displayed homology with the transposase of Pong. Here, we show that these sequences are differentially expressed during the in vitro androgenetic process in maize. We also demonstrate that the ZmTPAPong-like 1 and 3 sequences reveal somaclonal variations among plants regenerated from the calli of a doubled haploid line. These data suggest that the ZmTPAPong-like sequences could form part of a Zea mays element related to the rice Pong element. The possible activation of this newly discovered element under stress conditions is discussed.

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.
