Genetic analysis reveals significant differentiation in Scots pine populations, indicating unique ancestry in Armenia.

This research aims to investigate the genetic variation among Scots pine populations in Armenia and their relation to broader Eurasian lineages.
Genotyping 186 trees using the PiSy50k SNP array.
Integrating data with European datasets for comparative analysis.
Performing pairwise FST calculations and hierarchical AMOVA to assess genetic differentiation.
Conducting principal component analysis (PCA) to visualize genetic relationships.
Armenian stands showed high levels of within-population diversity.
AM1 exhibited reduced diversity and the highest differentiation compared to other populations.
Principal component analysis distinctly separated AM1 from non-Armenian samples.
Structural inference highlighted a dominant AM1 ancestry component and varied continental admixtures in AM2–AM4.

Degen et al. (2026) studied this question.
