Phylogenetic investigation of <i>Avena</i> diploid species and the maternal genome donor of <i>Avena</i> polyploids
Bibliographic record
Abstract
Abstract We investigated the species and genome relationships among 82 Avena accessions representing thirteen diploid species (A and C genomes), six tetraploids (AB and AC genomes) and four hexaploids (ACD genome) to infer the evolutionary pathways in Avena using the plastid matK gene and the trnL‐F region. The matK and trnL‐F sequences pointed to the A‐genome diploid species as maternal parents of the polyploid species. Furthermore, different A‐genome diploid species might have served as the A genome donor of several different polyploid species. The probable ancestor of most hexaploid species, of the AC‐genome tetraploids, and of the AB‐genome species A. agadiriana was A. wiestii (As genome). The likely donor of the other three AB‐ genome tetraploids was A. hirtula (also As genome) and A. damascena (Ad genome) appears to be the A genome donor of the hexaploid A. fatua. The A genome origin of A. fatua differs from that for the other hexaploid Avena species, which is different from the common assumption that the hexaploid species evolved from a single hexaploid ancestor followed by gain or loss of domestication genes. Thus, several separate maternal lineages might be involved in different polyploid species.

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.
