Biological studies of three caulimoviruses associated with dahlia (<i>Dahlia variabilis</i>)
Bibliographic record
Abstract
Two distinct caulimoviruses, Dahlia mosaic virus (DMV) and Dahlia common mosaic virus (DCMV), were found to be associated with dahlia mosaic disease. Additionally, an endogenous caulimovirus, Dahlia variabilis endogenous plant pararetroviral sequence (DvEPRS), was found to be present in many cultivated and wild Dahlia spp. Biological properties including mechanical and aphid transmission were investigated for DMV, DCMV and DvEPRS using Verbesina encelioides (crownbeard) as an experimental host. DMV and DCMV were transmitted by Myzus persicae at the rate of 50 and 73%, respectively. DMV and DCMV were mechanically transmissible to V. encelioides and the two effective buffers for mechanical transmission were phosphate buffer (pH 7.0) with nicotinic acid (1%) and sodium bisulfite (5%). Mechanical transmission rates of 58% and 36% were obtained for DMV and DCMV, respectively. DvEPRS was not transmissible by either aphids or mechanical inoculation. Availability of aphid and mechanical inoculation protocols for DMV and DCMV would facilitate further biological studies on caulimoviruses associated with Dahlia.
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.

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.
