The complete mitogenomes of the green algae <i>Jenufa minuta</i> and <i>Jenufa perforata</i> (Chlorophyceae, <i>incertae sedis</i>) reveal a variant genetic code previously unrecognized in the Chlorophyceae
Bibliographic record
Abstract
We sampled the first mitogenomes from a novel lineage of the Chlorophyceae that is sister to Sphaeropleales. Although the Jenufa perforata (27,180 bp) and Jenufa minuta (41,488 bp) mitogenomes differ markedly in size, gene order and intron content, their repertoires of conserved genes are essentially identical. Their rRNA genes display the same fragmentation patterns as their counterparts in Sphaeropleales. Their tRNA gene complements include two ancestral genes shared with Oedogoniales and Chaetophorales (Chlorophyceae) as well as a derived gene for a tRNA species decoding UGA as tryptophan. This noncanonical genetic code differs from those previously reported for Sphaeropleales.
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 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.
