The Metabolic and Genetic Bases of High Carotenoid Deposition in Orange-Fleshed Potato Tuber.

Journal of agricultural and food chemistry - 8 Jul 2026

Abstract excerpt

Orange-fleshed (O) potato tubers are rich in nutritionally beneficial carotenoids. However, the metabolic and regulatory mechanisms underlying their accumulation remain incompletely understood. Metabolomic profiling identified 32 carotenoids and showed that the O genotype reached peak carotenoid accumulation at the early swelling stage, with 17 xanthophylls present at higher levels than in a white-fleshed (W)...
