PATHOGENIC MECHANISM OF SCAB OF CUCUMBER CAUSED BY Cladosporium cucumerinum III EFFECTS AND SYNERGISM OF CELL WALL-DEGRADING ENZYMES AND TOXIN PRODUCED BY C.cucumerinum ON ULTRASTRUCTURE OF CUCUMBER
Bibliographic record
Abstract
The effects of the cellulase, pectinase and toxin produced by Cladosporium cucumeri num on the leaf cell of cucumber were studied by TEM and SEM. The results indicated that the three pathogenic factors played independent and symplastic roles. The cellulase and pectinase played leading roles respectively in decomposition of cell wall and plasma membrane. The three factors could all result in plasmolysis and damage vacuoles and endoplasmic reticulum. Chloroplast envelope and lamellae structure were mainly digested by cellulase, whiles, mitochondrion envelope was chiefly digested by the pectinase. Each of the three factors could cause vacuolation in chloroplast and mitochondria. During the process of breach up the structure of epidermis of leaf, the cellulase acted on reticulate region, then the pectinase dissolved pectic layer. Following this, palisade tissue was damaged by the cellulase, pectinase and toxin.Finally, parenchyma was destroyed by cellulase and toxin,successively.

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.
