Gibberellin reduces the susceptibility of rice, Oryza sativa, to the migratory nematode Hirschmanniella oryzae
Bibliographic record
Abstract
Summary Upon pathogen attack, the plant defence response is mediated by a set of connected signal transduction pathways, guided by several classes of plant hormones. In this study, experiments were conducted to observe the role of the plant hormone gibberellic acid in the response of rice to infection by the migratory root-rot nematode Hirschmanniella oryzae. Foliar treatments with gibberellic acid showed a negative effect on H. oryzae infection in the roots. Analyses of mutant rice lines impaired in the production or signalling of gibberellic acid confirmed the effect of the plant hormone on H. oryzae infection. Taken together, the results clearly indicate that gibberellic acid has a positive effect on the capability of the rice plant to fend off an infection by the migratory nematode H. oryzae.

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.
