Quantification of seven phloem-associated metabolites in six melon lines. Metabolites associated with the melon fascicular phloem were analysed by GC–MS (displayed in orange) and quantified as the area under the chromatogram peak (no units) corrected by leaf sample weight (g). Metabolites associated with the melon extra-fascicular phloem were analysed by LC–MS (displayed in light blue) and expressed as nM.mg⁻¹. Five melon plants were analysed four each melon genotype. PI 161375 and PI 482398 carry different Vat resistance alleles, Védrantais and Charentais T are susceptible to aphids. Their isogenic and near-isogenic lines with resistance donors are noted [Védrantais]^{R_PI 161375} and [Charentais]^{R_PI 482398}. Statistical comparisons were made between the Védrantais isogenic lines and between the Charentais T near-isogenic lines using a non- parametric bilateral Kruskal–Wallis test
