Metabolome profiles of peach accessions. a Summary of the experimental pipelines and data presented in this study. b Geographic distribution of peach accessions sampled in this study. Wild peaches, landraces, eastern improved varieties, and western improved varieties are indicated by pink, blue, green, and purple circles, respectively. c Principal component analysis of 252 peach accessions according to their metabolome profiles. d Heatmap of the relative levels of all annotated metabolites in four peach populations, wild (W), landraces (L), eastern improved varieties (EI), and western improved varieties (WI). Different classes of metabolites are plotted in the left column and shown in different colors. e Boxplots of representative metabolites in W, L, EI, and WI groups
