Allopolyploidization reduces alternative splicing efficiency for transcripts of the wheat<i>DREB2</i>homolog,<i>WDREB2</i>
Bibliographic record
Abstract
The wheat DREB2 homolog, WDREB2, encodes an EREBP/AP2-type transcription factor that activates downstream Cor/Lea genes and plays important roles in abiotic stress responses. WDREB2 expression is posttranscriptionally regulated by alternative splicing. In this study, the alternative splicing patterns of WDREB2 transcripts were compared among wheats of different ploidy levels. In diploid progenitors, alternative splicing rapidly produced functional forms from the WDREB2 transcripts and the levels of the nonfunctional form gradually decreased in response to drought stress; however, in hexaploid wheat lines, including both cultivars and synthetic lines, the nonfunctional form failed to decrease. The accumulation levels of the three spliced forms in synthetic allopolyploids were not equal to the sum of those in the parental lines. These results indicated that allopolyploidization during wheat polyploid evolution inhibited efficient alternative splicing of WDREB2 transcripts.

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.
