Quantitative metabolic profiles of tomato flesh and seeds during fruit development: complementary analysis with ANN and PCA (NMR data)

Global approach to characterize changes in metabolic profiles in two interdependent tissues Seed and Flesh from the same tomato fruits during tomato fruit development. Tomato, an essential crop in terms of economic importance and nutritional quality, is also used as a model species for all fleshy fruits and for genomics of Solanaceae. Tomato fruit quality at harvest is a direct function of its metabolite content, which in turn is a result of many physiological changes during fruit development. The aim of the work reported here was to develop a global approach to characterize changes in metabolic profiles in two interdependent tissues from the same tomato fruits. Absolute quantification data of compounds in flesh and seeds from 8 days to 45 days post anthesis (DPA) were obtained through untargeted (proton nuclear magnetic resonance, 1H-NMR).
