Herpes-like viral elements and universal subtelomeric ribosomal RNA genes in a chromosome-scale thraustochytrid genome assembly
Bibliographic record
Abstract
ABSTRACT We used long-read sequencing to produce a telomere-to-telomere genome assembly for the heterotrophic stramenopile protist Aurantiochytrium limacinum MYA-1381. Its ∼62 Mbp nuclear genome comprises 26 linear chromosomes with a novel configuration: subtelomeric rDNAs are interspersed with long repeated sequence elements denoted as LOng REpeated - TElomere And Rdna Spacers (LORE-TEARS). These repeats may play a role in chromosome end maintenance. A ∼300 Kbp circular herpesvirus-like genomic element is present at a high copy number. A 269 Kbp related virus-like element was found to reside between two complete sets of rRNA and LORE-TEAR sequences on one end of chromosome 15, indicating recent recombination between the viral and nuclear genome. Our data reveal new types of giant endogenous viral elements originating from herpes-like viruses and existing as either ‘stand-alone’ or integrated elements.
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.
