Many solanaceous crops are an important part of the human daily diet. Fruit polyphenolics
are plant specialized metabolites that are recognized for their human health benefits and their
defensive role against plant abiotic and biotic stressors. Flavonoids and chlorogenates are the
major polyphenolic compounds found in solanaceous fruits that vary in quantity, physiological
function, and structural diversity among and within plant species. Despite their biological significance,
the elucidation of metabolic shifts of polyphenols during fruit ripening in different fruit tissues, has not
yet been well-characterized in solanaceous crops, especially at a cross-species and cross-cultivar level.
Here, we performed a cross-species comparison of fruit-metabolomics to elucidate the metabolic
regulation of fruit polyphenolics from three representative crops of Solanaceae (tomato, eggplant,
and pepper), and a cross-cultivar comparison among different pepper cultivars (Capsicum annuum cv.)
using liquid chromatography-mass spectrometry (LC-MS). We observed a metabolic trade-off between
hydroxycinnamates and flavonoids in pungent pepper and anthocyanin-type pepper cultivars and
identified metabolic signatures of fruit polyphenolics in each species from each different tissue-type
and fruit ripening stage. Our results provide additional information for metabolomics-assisted
crop improvement of solanaceous fruits towards their improved nutritive properties and enhanced
stress tolerance.
