Identification of candidate genes in the lead SNP hotspots associated with flavonoids. a Heatmap of profiles of all flavonoids detected in this study. The relative flavonoid contents in wild peaches (W) and landraces (L) were scaled to the improved varieties (I) group for each metabolite. Numbers 1 to 39 correspond to the 1st to 39th flavonoids in Additional file 2: Table S2. b Correlation index between metabolite contents and their antioxidant activities in the sampling panel. c Manhattan plots of mGWAS of quercetin 3-O-glucoside in 2016. d Contents of chrysoeriol 5-O-hexoside and quercetin 3-O-glucoside and expression of Prupe. 5G006200 and Prupe.5G032800 in peach variety “Zheng Bai 5-6#” during fruit development. e Network between candidate genes regulated by a trans-eQTL (Chr. 7: 18,797,533 bp) and corresponding metabolites. Blue lines indicate the regulations between eQTLs (green circle on Chr. 7) and target genes (purple boxes on Chr. 5). The gray dotted lines indicate the correlations between gene and metabolites
