Abstract
The Pseudomonas putida isolate BTP1 and its sid − mutant M3 were recently reported to protect cucumber against Pythium aphanidermatum root rot. This protection was mainly associated with an accumulation of antifungal phenolics in the treated roots. In this study, analyses of root extracts from split‐root experiments showed that these phytoalexins were produced systemically. Indeed, several antifungal molecules accumulated similarly in both treated and nontreated root parts of plants protected against P. aphanidermatum with BTP1 or M3. In addition, analyses of leaf samples also revealed increased amounts of fungitoxic molecules in PGPR‐treated plants, although the nature of these molecules appeared to be different from those detected in roots. The antifungal compounds isolated both from roots and leaves were mainly detected in acid‐hydrolyzed extracts containing aglycones. These results suggest that PGPR can elicit phytoalexins systemically in cucumber and that the overall defence response is not based on a single phytoalexin but is chemically complex and organ‐specific.

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
