Abstract
The trnS/psbC region of chloroplast DNA (cpDNA) was sequenced for 18 Elymus polyploid species, Hordelymus europaeus and their putative diploid ancestors. The objective was to determine the maternal origin and evolutionary relationships of these polyploid taxa. Phylogenetic analysis showed that Elymus and Pseudoroegneria species formed a highly supported monophyletic group (100 % bootstrap values), suggesting that Pseudoroegneria is the maternal genome donor to polyploid Elymus species studied here. The phylogenetic tree based on cpDNA sequence data indicates that E. submuticus contains a St-genome. Taking into consideration of our previously published RPB2 data, we can conclude that hexaploid E. submuticus contains at least one copy of St and Y genomes. Our Neighor-joining analysis of cpDNA data put Psathyrostachys juncea, Hordeum bogdanii and Hordelymus europaeus into one group, suggesting a close relationship among them.

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
