a Neighbor-joining tree of 191 allotetraploid perilla accessions. Green, yellow, and purple branches indicated three perilla clades of south China (n = 120), north China (26), and crispa (45), respectively. Totally 4,789,738 filtered high-quality SNPs were used for tree construction. b PCA analysis of these samples with the same SNP dataset. c Population structure of these samples based on different numbers of clusters (K = 2–4). d Nucleotide diversity (π) and population divergence (FST) across the three clades. The value in each circle indicates calculated nucleotide diversity for that clade, and the value along each line represents population divergence between two neighboring clades. e Neighbor-joining tree constructed with 108,850 PFA-specific SNPs, and overlaid with leaf color information: dashed lines indicated green leaves, and solid lines represented red leaf phenotype. Color codes were the same in (a), (b), (d), and (e).
