Contribution of Boundary Genes to Fruit Patterning and Dehiscence in Arabidopsis Thaliana
Bibliographic record
Abstract
Fruit production is an evolutionary innovation that allows for seed dispersion. Brassica members including the model plant species Arabidopsis thaliana produce dry fruits that shatter when ripe, a process called dehiscence. The Arabidopsis fruit is a pod composed of two fused valves whose margins are joined to a central seed-bearing replum. The valve margins are specialized zones for dehiscence, related to boundaries that separate leaves from the shoot apical meristem. BLADE-ON-PETIOLE1/2 (BOP1/2) co-activators interact with Clade I TGA transcription factors to promote the activation of three-amino-acid-loop-extension (TALE) homeobox genes, important for boundary development. My data show that boundary genes enhance the expression of valve margin identity genes. Further, boundary genes are constrained to the valve margin by mechanisms similar to valve margin identity genes. Finally, boundary gene mutations modulate replum width and generate shatter-resistant fruits. Manipulation of this pathway provides a new potential strategy for optimizing pod shatter in crops.

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.
