Abstract
Abstract In Brassicaceae, myrosinase catalyzes the hydrolysis of glucosinolate and plays an important role in anti‐herbivore defense. We have cloned and characterized the full‐length complementary DNA of myrosinase gene from Brassica parachinensis that exhibits high sequence identity with myrosinase genes from other Brassica species. To investigate the role of this myrosinase in defense against the diamondback moth ( Plutella xylostella ), we constructed an RNA‐interference (RNAi) cassette expressing a double‐stranded RNA that targeted myrosinase and transfected it into B. parachinensis . Myrosinase was suppressed in the resulting transgenic plants. Diamondback moth larvae feeding on transgenic plants had lower larval and pupal weights, longer pupal duration, and lower fecundity than those feeding on non‐transgenic plants, suggesting that the diamondback moth has adapted to the glucosinolate‐myrosinase defensive system. Therefore, the suppression of myrosinase is a potential approach for controlling the diamondback moth.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
