Abstract
Potato wart disease caused by the obligate biotrophic fungus Synchytrium endobioticum is a devastating disease that can result in significant crop losses. Resting spores of this pathogen can remain viable and infectious in soil for decades. The detection of viable resting spores using conventional methods such as bioassays and direct microscopic examination are challenging and time-consuming and require specific expertise and facilities. Molecular methods, such as real-time PCR, have been shown to be effective in detecting the presence of S. endobioticum DNA in soil samples but cannot differentiate between viable and nonviable spores. In this paper, we present three novel mRNA-based molecular tests to potentially detect viable S. endobioticum resting spores. The tests are specific to the transcribed mRNA and do not detect the genomic DNA of the target genes. We demonstrate the analytical sensitivity using synthetic constructs of the target mRNAs. The tests were found to be able to repeatedly detect 10 target copies per reaction. Soils and waste of potato processing industries free from S. endobioticum were used to assess the exclusivity of the tests. The biological relevance of mRNA detection was determined in the context of replicated bioassays. Applications of the tests to facilitate collection management, assessment of the effects of treatments on presumed viability of S. endobioticum resting spores, and the potential use in descheduling of previously infested plots are discussed.

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
