Identification and Characterization of a Putative Baculoviral Transcriptional Factor IE-1 from Choristoneura fumiferana Granulovirus
Bibliographic record
Abstract
A gene that encodes a protein homologue to baculoviral IE-1 was identified and sequenced in the genome of the Choristoneura fumiferana granulovirus (ChfuGV). The gene has an 1278 nucleotide (nt) open-reading frame (ORF) that encodes 426 amino acids with an estimated molecular weight of 50.33 kDa. At the nucleotide level, several cis-acting regulatory elements were detected within the promoter region of the ie-1 gene of ChfuGV along with other studied granuloviruses (GVs). Two putative CCAAT elements were detected within the noncoding leader region of this gene; one was located on the opposite strand at -92 and the other at -420 nt from the putative start triplet. Two baculoviral late promoter motifs (TAAG) were also detected within the promoter region of the ie-1 gene of ChfuGV. A single polyadenylation signal, AATAAA, was located 18nt downstream of the putative translational stop codon of ie-1 from ChfuGV. At the protein level, the amino acid sequence data that was derived from the nucleotide sequence in ChfuGV IE-1 was compared to those of the Cydia pomonella granulovirus (CpGV), Xestia c-nigrum granulovirus (XcGV) and Plutella xylostella granulovirus (PxGV). The C-terminal regions of the granuloviral IE-1 sequences appeared to be more conserved when compared to the N-terminal regions. A domain, similar to the basic helix-loop-helix like (bHLH-like) domain in NPVs, was detected at the C-terminal region of IE-1 from ChfuGV (residues 387 to 414). A phylogenetic tree for baculoviral IE-1 was constructed using a maximum parsimony analysis. A phylogenetic estimation demonstrates that ChfuGV IE-1 is most closely related to that of CpGV.

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.
