Proteome Changes in Leaves of Brassica napus L. as a Result of Sclerotinia sclerotiorum Challenge
Bibliographic record
Abstract
Sclerotinia stem rot, caused by the necrotrophic fungal pathogen Sclerotinia sclerotiorum, is a serious disease of canola (Brassica napus L.). To increase the understanding of the B. napus- S. sclerotiorum interaction, proteins potentially involved in mediating this interaction were identified and characterized. Upon infection of canola leaves by S. sclerotiorum, necrosis of host leaves was observed by 12 h and rapidly progressed during the later time points. These morphological observations were supported by microscopic study performed at different time points after pathogen challenge. Leaf proteins were extracted and analyzed by 2-DE, which revealed the modulation of 32 proteins (12 down- and 20 up-regulated). The identities of these proteins were established by ESI-q-TOF MS/MS and included proteins involved in photosynthesis and metabolic pathways, protein folding and modifications, hormone signaling, and antioxidant defense. Gene expression analysis of selected genes was performed by qRT-PCR, whereas the elevated levels of the antioxidant enzymes peroxidase and superoxide dismutase were validated by enzyme assays. To the authors' best knowledge, this is the first proteomics-based investigation of B. napus-S. sclerotiorum interaction, and the roles of many of the proteins identified are discussed within the context of this pathosystem.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
