Abstract
Complete chloroplast genome of diatom alga Synedra acus possesses canonical quadripartite structure with two inverted repeats containing ribosomal RNA gene loci that separate small and large single-copy regions. Chloroplast genome maps as a circular molecule of 116 251 bp. It encodes 27 tRNAs, three rRNAs, two small RNA genes, and 128 protein-coding genes. Comparison of the genic features across diatom chloroplast genomes reveals the absence of an overlap between atpD and atpF gene coding sequences that is present in other plastid genomes of diatom origin. This feature is a clear synapomorphy of S. acus plastid genome that is likely a result of either relaxed constraints or extensive selection forces acting upon atpF gene. We also characterized nuclear-encoded acyl-carrier protein gene with chloroplastic targeting in S. acus. The transfer of acpp gene into the nuclear host genome is hypothesized to have occurred independently in several lineages of diatoms.
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 it
