<i>Blueberry fruit drop-associated virus</i>: A New Member of the Family <i>Caulimoviridae</i> Isolated From Blueberry Exhibiting Fruit-Drop Symptoms
Bibliographic record
Abstract
This study describes the nucleotide sequence and genome organization of a new DNA virus isolated from 'Bluecrop' blueberry plants exhibiting fruit-drop symptoms and named Blueberry fruit drop-associated virus (BFDaV). Blueberry fruit drop disease was first detected in blueberry plants in British Columbia, Canada in the late 1990s, and in a single field in northern Washington state in the United States in 2012. Infected bushes abort nearly 100% of their fruit about three weeks prior to harvest, when the berries are about 3 to 5 mm in diameter. At harvest, the affected plants appear taller than healthy ones as there is no fruit weighing down the branches. The virus was amplified from diseased material using rolling circle amplification, followed by enzyme digestion, cloning, and sequencing. The full genome of BFDaV is 9,850 bp in length and contains a single open reading frame, encoding for a polyprotein, and a large noncoding region. Based on the genome size and organization and phylogenetics, BFDaV is proposed as a new and the largest member of family Caulimoviridae. Finally, in mapping part of a field with fruit-drop symptoms, there was a nearly perfect correlation between the presence of the virus and fruit-drop symptoms.
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.
