Detection of<i>Switchgrass mosaic virus</i>in<i>Miscanthus</i>and other grasses
Bibliographic record
Abstract
A new marafivirus tentatively named Switchgrass mosaic virus (SwMV) was recently detected in Panicum virgatum L. (switchgrass). The virus is related to Maize rayado fino virus (MRFV). As Miscanthus and other grass species are grown alongside switchgrass in our experimental fields, there has been concern that the virus could be transmitted to these plants. To investigate this possibility, leaf samples from Miscanthus spp. and other grasses rotated with switchgrass in a field planting were tested for SwMV by reverse-transcriptase polymerase chain reaction (RT-PCR). Switchgrass mosaic virus was detected in leaf samples of Miscanthus × giganteus, M. sinensis, M. transmorrisonensis, Saccharum ravennae, Andropogon virginicus and Sorghastrum nutans. The nucleotide sequences of the amplicons from these samples were 99% identical to SwMV in switchgrass. This is the first report of SwMV detection in Miscanthus spp. and the other grasses, apart from switchgrass.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
