Streptomyces felleus YJ1: Potential Biocontrol Agents Against the Sclerotinia Stem Rot (Sclerotinia sclerotiorum) of Oilseed Rape
Bibliographic record
Abstract
In order to explore the biocontrol potential of Streptomyces felleus YJ1 to sclerotinia stem rot of oilseed rape, we evaluated the effects of YJ1 as antagonistic strain on Sclerotinia sclerotiorum, including germination and formation of sclerotia, ascospore germination, mycelial growth and YJ1 colonization ability. We found the fermentation filtrate of YJ1 could inhibit sclerotia and ascospore germination and mycelial growth. In dual culture the inhibition zone diameter of YJ1 against S. sclerotiorum was 11.0 mm, and the inhibition rate reached to 80.26%. The ascospores germination was also significantly inhibited by YJ1 fermentation filtrate. In addition, YJ1 could colonize stably in rhizosphere and roots of rape. Otherwise, in the greenhouse we found the lesion would become smaller and slighter if the inoculated leaves were pretreated with YJ1 fermentation liquid. Therefore, our results strongly suggested that YJ1 was a promising biocontrol agent for control of oilseed rape sclerotinia stem rot.

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.
