Flavonoid concentrations and gene expression. (a) flavonol (b) anthocyanin concentrations and (c) flavonoid gene expression in tubers from six locations. PtCRG, PeCRG, CyCRG, DeCRG, MaCRG are 3-coumuryol rutinoside 5-glucoside conjugates of petunidin, peonidin, cyanidin, delphinidin, and malvidin respectively; Ptd, petunidin derivative; Myr, myricetin-3-O-rutinoside; Rut, quercetin-3-O-rutinoside; Kmp, kaempferol-3-O-rutinoside. The data represents the means ± SE of three biological replicates. Locations with same letter are not significantly different (p < 0.05)
