Insect Regurgitant and Wounding Elicit Similar Defense Responses In Poplar Leaves
Bibliographic record
Abstract
How plants perceive insect attacks is an area of active research. Numerous studies have shown that regurgitant from feeding insects elicits a defense response in plants, which is often assumed to be distinct from a wound response. We have characterized the inducible defense response in hybrid poplar and found it to be qualitatively similar between wounding and application of regurgitant from forest tent caterpillar. We suggest that this is likely attributable to our wounding treatment which is much more intense compared to most other studies. These overlapping responses appear to be activated via jasmonic acid signaling, and we speculate that they are both triggered by elicitors of plant origin. Wounding would release such elicitor molecules when leaf cells are disrupted, and regurgitant may contain them in a modified or processed form. This hypothesis could explain why some other necrosis-inducing stresses also induce herbivore defense genes.

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.
