Endogenous avian leukosis viral loci in the Red Jungle Fowl genome assembly
Bibliographic record
Abstract
The current build (galGal4) of the genome of the ancestor of the modern chicken, the Red Jungle Fowl, contains a single endogenous avian leukosis viral element (ALVE) on chromosome 1 (designated RSV-LTR; family ERVK). The assembly shows the ALVE provirus juxtaposed with a member of a second family of avian endogenous retroviruses (designated GGERV20; family ERVL); however, the status of the 3' end of the ALVE element as well as its flanking region remain unclear due to a gap in the reference genome sequence. In this study, we filled the gap in the assembly using a combination of long-range PCR (LR-PCR) and a short contig present in the unassembled portion of the reference genome database. Our results demonstrate that the ALVE element (ALVE-JFevB) is inserted into the putative envelope region of a GGERV20 element, roughly 1 kbp from its 3' end, and that ALVE-JFevB is complete, and depending on its expression status, potentially capable of directing the production of virus. Moreover, the unassembled portion of the genome database contains junction fragments for a second, previously characterized endogenous proviral element, ALVE-6.

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.
