Auxinic Herbicide Resistance in Wild Mustard (<i>Sinapis arvensis</i> L.)
Bibliographic record
Abstract
Plant species resistant to auxinic herbicides have been identified and the basis for this resistance remains unclear. Our objectives are to understand the molecular mechanism(s) of auxinic herbicide resistance in wild mustard ( Sinapis arvensis L.). In order to achieve this objective, we characterized both a susceptible (S) and resistant (R) biotype of wild mustard at the biochemical, physiological and molecular levels (Table 1). When the S and R biotypes were compared, there were no differences in the uptake, transport and metabolism of auxinic herbicides. However, significant differences in auxinic herbicide-induced ethylene biosynthesis were observed between the two biotypes. We have recently studied the role of auxinic herbicide-induced ethylene on root morphology. Biophysical studies indicate an important role for calcium in mediating the resistance phenomenon. Furthermore, molecular analysis of auxin-binding proteins (ABPs) from both biotypes revealed important differences in the structure of this putative auxin receptor, which may be crucial for the development of resistance.

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.
