Abstract
To better understand the pathogen-stress response of Brassica species against the ubiquitous hemi-biotroph fungus Leptosphaeria maculans, we conducted a comparative proteomic analysis between blackleg-susceptible Brassica napus and blackleg-resistant Brassica carinata following pathogen inoculation. We examined temporal changes (6, 12, 24, 48 and 72 h) in protein profiles of both species subjected to pathogen-challenge using two-dimensional gel electrophoresis. A total of 64 proteins were found to be significantly affected by the pathogen in the two species, out of which 51 protein spots were identified using tandem mass spectrometry. The proteins identified included antioxidant enzymes, photosynthetic and metabolic enzymes, and those involved in protein processing and signaling. Specifically, we observed that in the tolerant B. carinata, enzymes involved in the detoxification of free radicals increased in response to the pathogen whereas no such increase was observed in the susceptible B. napus. The expression of genes encoding four selected proteins was validated using quantitative real-time PCR and an additional one by Western blotting. Our findings are discussed with respect to tolerance or susceptibility of these species to the pathogen.

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
