Complete chloroplast genome sequence of the medicinal plant <i>Arctium</i> <i>lappa</i>
Bibliographic record
Abstract
Arctium lappa, commonly called burdock, has a long medicinal and edible history. It has recently gained increasing attention because of its economic value. In this study, we obtained the complete chloroplast genome of A. lappa by Illumina Hiseq. The complete chloroplast genome of A. lappa is a typical circular structure with 152 708 bp in length. The GC content in the whole chloroplast genome of A. lappa is 37.7%. A total of 37 tRNA genes, 8 rRNA genes, and 87 protein-coding genes were successfully annotated. And the chloroplast genome contains 113 unique genes, 19 of which are duplicated in the inverted repeat. The distribution of 39 simple sequence repeats was analysed, and most of them are in the large single-copy (LSC) sequence. An inversion comprising 16 genes was found in the LSC region, which is 26 283 bp long. We performed multiple sequence alignments using 72 common protein-coding genes of 29 species and constructed a Maximum Parsimony (MP) tree. The MP phylogenetic result shows that A. lappa grouped together with Carthamus tinctorius, Centaurea diffusa, and Saussurea involucrata. The chloroplast genome of A. lappa is a valuable resource for further studies in Asteraceae.
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.
How this classification was reachedexpand
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.
