Abstract

fetched live from OpenAlex

High Resolution Image Download MS PowerPoint Slide Our research focused on developing a highly sensitive whole-spore real-time immuno-PCR (RT-iPCR) assay for the detection of three wheat fungal pathogens: Pyrenophora tritici-repentis ( Ptr ), Fusarium graminearum ( Fg ), and Puccinia striiformis forma specialis (f. sp.) tritici ( Pst ). RT-iPCR measurements were compared to more well-established quantitative PCR (qPCR) assays to compare their performance. While specificity remained a challenge for RT-iPCR, the direct spore measurements negate the need for DNA extraction, making RT-iPCR a potentially valuable technique that warrants further research. An alternative approach was developed to determine DNA extraction efficiency and quantification of spore numbers by qPCR, which is currently a methodological gap in most qPCR spore measurements. DNA extraction efficiency determined for Fg, Pst, and Ptr spores were 5.0 ± 0.1, 7.0 ± 0.4, and 290 ± 36%, respectively, demonstrating important implications for the accuracy of these techniques when DNA recovery is not considered.

Teacher imitation

Not 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.
