Abstract
Understanding the infection biology of fungi is the key step in devising suitable control strategies for plant diseases. Recently, the Arabidopsis-Colletotrichum higginsianum (causal agent of anthracnose) system has emerged as a seminal paradigm for deciphering the infection biology underlying fungus-plant interactions. We describe here three staining methods coupled with confocal microscopy: trypan blue, aniline blue and dual trypan blue-aniline blue fluorescence staining. Trypan blue and aniline blue staining were employed to scan the infection structures of the hemibiotrophic fungus C. higginsianum and host response in A. thaliana leaf tissues. The two techniques then were combined to observe the contrast between in planta fungal infection structures, i.e., infection vesicles, primary hyphae and secondary hyphae, and the host plant defense responses, i.e., papilla formation and hypersensitive response. These staining techniques also were applied to the lentil-C. truncatum pathosystem to demonstrate their applicability for multiple pathosystems.

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
