Microsatellite DNA markers for the Sri Lankan rainforest tree species, <i>Shorea cordifolia</i> (Dipterocarpaceae), and cross‐species amplification in <i>S. megistophylla</i>
Bibliographic record
Abstract
Abstract We developed microsatellite primer pairs for the tropical tree species, Shorea cordifolia , of genus Shorea section Doona , an endemic and dominant group of Sri Lanka's rainforests. From an (AG) n ‐enriched library, 30 positive clones were screened, yielding 21 unique microsatellite loci. We used oligonucleotide primer pairs designed for 13 loci to screen genomic DNA from 90 adults. For seven polymorphic loci, the number of alleles and gene diversity per locus ranged from 4 to 18 and 0.36 to 0.90, respectively. Because all seven loci amplified easily in a close relative, S. megistophylla , we expect that these primers will be transferable to other Doona species.
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.

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.
