The Colonization Process of Sunflower by a Green Fluorescent Protein-Tagged Isolate of <i>Verticillium dahliae</i> and its Seed Transmission
Bibliographic record
Abstract
Sunflower Verticillium wilt is a widespread and destructive disease caused by the soilborne pathogen Verticillium dahliae. To better understand the process of infection and seed transmission of the fungus, sunflower roots were inoculated with a V. dahliae strain (VdBM9-6) labeled with green fluorescent protein (GFP) and monitored microscopically. After 24 to 96 h postinoculation (hpi), conidia germinated and developed into mycelium on root hairs, elongation zones, and caps of lateral roots. Mycelium colonized vascular bundles of lateral roots and taproots at 7 days postinoculation (dpi). At 10 weeks postinoculation (wpi), the epidermal cells, cortical tissues, and vascular elements of stem, petiole, and leaf veins were colonized by mycelium. By 12 wpi, strong GFP signals were detected not only on different tissues of inflorescence but also on testa of seed and a small fraction of pollen grains. A GFP signal was not observed on cotyledon tissues in the seed. Additionally, the colonization of V. dahliae on testa was also confirmed with MNP-10 selection medium, indicating that the testa of seed is the main carrier for the long distance transmission of sunflower yellow wilt.

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.
