<i>Populus</i> genotypes differ in infection by, and systemic spread of, <i>Poplar mosaic virus</i>
Bibliographic record
Abstract
The spatial and temporal dynamics of Poplar mosaic virus (PopMV) infection were investigated using four different genotypes of Populus . Four Populus clones were vegetatively propagated under sterile conditions and used as hosts for PopMV infection in controlled growth‐room experiments. The presence of PopMV RNA was assessed using reverse transcriptase PCR. The presence of infectious PopMV particles was assessed by the ability of extracts from Populus leaves to generate PopMV symptoms on the propagation host, Nicotiana megalosiphon . Neither PopMV RNA nor infectious particles accumulated to detectable levels in one of the four clones (CT6009), suggesting that this clone had preformed resistance to PopMV. PopMV RNA and infectious particles were restricted to the inoculated leaf in two of the clones (AP37 and NM6), suggesting that these clones restricted either the rate of virus accumulation or the spread of PopMV itself. In contrast, PopMV systemically infected one clone (52‐226), indicating that this host was either fully susceptible, or had delayed resistance.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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.
