Sequencing of the transcriptome of asarum canadense and comparison with intrageneric species using a chloroplast gene
Bibliographic record
Abstract
There has been much interest in identifying chemical compounds in the species of the genus Asarum due to their potential use in medicinal treatments. As a result, interest has also been generated in sequencing the genomes or transcriptomes of species within this genus to clarify their taxonomic relationships. In this study, a transcriptome of the chloroplast of the North American species Asarum canadense (Canadian wild ginger) was sequenced. The plastid sequence matK was used for comparison with other intrageneric species. Analysis with MEGA shows that A. canadense is most closely related to A. caudatum, a species found in western North America, and A. europaeum, a widespread European species. These 3 species were shown to be more distantly related to A. debile, an Asian species, forming a monophyletic group. This analysis supports the existing hypothesis that a section of the genus Asarum originated in Asia and then moved to Europe and North America. However, many of the relationships within this genus are unclear and should be studied in more depth.

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.
