Colonization of Streptomyces felleus YJ1 and Its Effects on Disease Resistant-Related Enzymes of Oilseed Rape
Bibliographic record
Abstract
Streptomyces felleus YJ1 has strong antagonism against Sclerotinia sclerotiorum, and it can be used for preventing this fungal disease in oilseed rape in the greenhouse. Under greenhouse conditions, we determined the colonization dynamic variation of YJ1 in soil and rape; and the changes of defensive enzymes of rape induced by YJ1 were measured. The results showed that, YJ1 could colonize chronically in soil; and it could also colonize in roots of rape and conduct to the stem and leaves, suggesting good colonization potential. After the rapes were processed by YJ1 fermentation liquid broth, the changes of defensive enzymes (SOD, PPO, POD etc.) in rape were measured. The results showed that, the activities of defensive enzymes changed significantly, especially in the four days later, the SOD, POD, PPO and PAL activities were significantly higher than that of inoculated with S. sclerotiorum and control, and maintained at a high level. Those results indicated that induced systemic resistance of rape maybe one of antagonistic mechanism of YJ1 against S. sclerotiorum.

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.
