P34.8 (GP37) is not essential for baculovirus replication
Bibliographic record
Abstract
Previous reports have indicated that p34.8 (gp37) may be essential for the replication of Autographa californica nucleopolyhedrovirus (AcMNPV) because no virus with inactivated p34.8 was isolated. We have ascertained the requirement for this gene by attempting to inactivate it with a large insertion [the gene encoding GFP (green fluorescent protein)] or by deleting all the conserved domains from the open reading frame (ORF). The gene encoding GFP was inserted into the NOT:I site of the p34.8 ORF and a viral plaque containing the insertion was propagated in SF-21 cells. Similarly, 531 bp (NOT:I-XBA:I) containing all conserved domains were deleted from the ORF. All mutants were authenticated by PCR amplification, restriction endonuclease analysis, DNA sequencing, and Southern and Northern blot analysis. It was found that inactivation of p34.8 of AcUW1-LacZ (AcMNPV containing a lacZ gene in the p10 locus) had no effect on the biological property of virus, such as virulence and kinetics. These two independent methods showed that p34.8 is not essential for replication and that this locus could provide another site for the engineering of baculoviruses.
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.
