Abstract

fetched live from OpenAlex

The ability of nonpathogenic isolates of Fusarium oxysporum (np Fo ) to induce systemic resistance and defence responses against subsequent challenge with a pathogenic strain of F. oxysporum f. sp. asparagi ( Foa ) was examined in Asparagus officinalis . In a split‐root experiment, roots inoculated with np Fo exhibited a hypersensitive response and those subsequently inoculated with Foa displayed resistance. Induction of systemic resistance in np Fo ‐treated plants led to significantly fewer necrotic lesions ( P = 0·05) and reduced Foa disease severity compared with plants not treated with np Fo . In hyphal‐sandwich root inoculation experiments, activities of peroxidase and phenylalanine ammonia‐lyase and lignin content were higher in np Fo ‐treated plants and increased more rapidly than in np Fo ‐untreated plants after Foa inoculation. Antifungal activity (inhibition of fungal spore germination and germ‐tube growth) from exudates of roots inoculated with Foa were observed for np Fo ‐treated plants but not for np Fo ‐untreated plants. Thus, isolates of np Fo may function as inducers of systemic acquired resistance (SAR) and defence responses against Foa invasion in A. officinalis .

Teacher imitation

Not 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.
