a NJ tree of 120 ancient tea plants inferred from SNPs at fourfold degenerate sites. A phylogenetic tree was constructed using MEGA software with default parameters. b Model-based Bayesian clustering of 120 ancient tea plants performed using ADMIXTURE Version 1.3.0 with the number of ancestry kinships (K) set to 2–7. Each accession is denoted by a vertical bar composed of different colors corresponding to its proportion of genetic ancestry from each of these populations. c Principal component analysis of the 120 ancient tea plants. d The geographic origin of each accession in the seven clades
