Abstract

fetched live from OpenAlex

Boundaries that join lateral organs to the plant body are an important determinant of plant architecture.These specialized junctions originate within the shoot apex and control leaf shape, branching architecture, and abscission.Boundary patterning relies on a pair of BTB-ankyrin co-transcription factors encoded by BLADE-ON-PETIOLE 1 and 2 (BOP1/2).Members of this class bind to DNA indirectly, by interacting with other types of transcription factors, especially TGACG-motif binding (TGA) basic leucine zipper proteins.My works shows a previously undiscovered role for clade III TGA factors, previously associated with plant defense, in BOP-dependent plant development.This work uncovers a dual role for clade III TGAs in development and defense.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
