Genetic structure of 146 Japanese apricot chloroplast genomes. a Principal component analysis (PCA). b The phylogenetic tree was established by SNPs based on maximum likelihood. The inner circle represents the phylogenetic tree constructed based on SNPs of 146 chloroplast genomes, and the outer circle is the KA/KS values heatmap of gene rpoC2, matK, rbcL, rpl22, ndhF, ccsA, and ndhI between Prunus mume and Prunus persica. c Population structure analysis of the 146 Japanese apricot accessions. Branch A to E represented the clustering information of population structure results, which corresponds to the phylogenetic tree
