Transcriptome‐derived microsatellite markers for <i>Dioon</i> (Zamiaceae) cycad species
Bibliographic record
Abstract
PREMISE OF THE STUDY: Dioon (Zamiaceae) is an endangered North American cycad genus of evolutionary and ornamental value. We designed and validated a set of microsatellite markers from D. edule that can be used for population-level and conservation studies, and that transferred successfully to D. angustifolium, D. spinulosum, and D. holmgrenii. METHODS AND RESULTS: We tested 50 primers from 80 microsatellite candidate loci in the OneKP D. edule transcriptome. Genotypes from 21 loci in 20 D. edule individuals revealed up to 14 alleles per locus and observed heterozygosity from 0.15 to 0.92; one locus was monomorphic. Seven of those 21 loci were polymorphic in D. angustifolium, D. spinulosum, and D. holmgrenii, with up to seven alleles, and an observed heterozygosity up to 0.89. CONCLUSIONS: The transcriptome-derived microsatellites generated here will serve as tools to advance population genetic studies and inform conservation strategies of Dioon, including the identification and origin of illegal plants in the cycad trade.

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.
