GY, “Green Peel” young fruit; PY, “Purple Peel” young fruit; GM, “Green Peel” mature fruit; PM, “Purple Peel” mature fruit. Metabolite fold changes, value >1.0 represents increase; value < 1.0 represents decrease. Differentially accumulated phenolic compounds were identified by threshold VIP (variable importance in projection) ≥1, and fold change ≥2 (upregulation) or ≤ 0.5 (downregulation).
