The mtDNA <i>rps3</i> locus has been invaded by a group I intron in some species of <i>Grosmannia</i>
Bibliographic record
Abstract
The mitochondrial rps3 gene in some filamentous ascomycetes fungi is encoded within an rnl group I intron. In Grosmannia piceiperda the N-terminal segment of the intron-encoded rps3 gene has been invaded by an IC2-type group I intron. This intron disrupts the recipient rps3 and fragments this gene into two open reading frames (ORFs). The IC2 group I intron encodes a putative double-motif LAGLIDADG ORF, which is fused in-frame to the upstream rps3 exon sequence. The presence of the LAGLIDADG amino acid motif is indicative of an enzyme that has endonuclease and/or maturase activity and thus the intron encoded protein could be involved in promoting splicing and mobility. Reverse transcriptase polymerase chain reaction (RT-PCR) confirmed that this intron is spliced in vivo and as a result this could allow for the expression of a functional ribosomal Rps3 protein.
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.
