Investigating the Multiple Roles of Boundary Genes in Abscission in Arabidopsis thaliana
Bibliographic record
Abstract
Plants shed organs through abscission.This process scatters seeds and removes foliage but can reduce crop yield if unmanaged.In the model plant species, Arabidopsis thaliana, the outer parts of the flower are shed after pollination.BLADE-ON-PETIOLE boundary genes initiate abscission zones (AZ) where separation occurs.This work focused on the abscission role of boundary Three-Amino-Acid-Loop-Extension (TALE) homeodomain transcription factor genes KNOTTED1-LIKE FROM ARABIDOPSIS THALIANA 2 (KNAT2), KNOTTED1-LIKE FROM ARABIDOPSIS THALIANA 6 (KNAT6), and functional partner ARABIDOPSIS THALIANA HOMEOBOX GENE 1 (ATH1).I show that TALE boundary genes are required for the correct formation of two distinct layers that develop after specification of the AZ.Collective loss of TALE activity disrupts the proper formation of both layers.I also show that TALE boundary genes are active in the signalling pathway that activates abscission, and promote the production of hydrolytic enzymes.I propose that TALE boundary genes contribute to multiple steps of the abscission process.150/

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.
