Abstract Seeds of Brassicaceae species produce a large diversity specialized metabolites (SMs) that strongly influence their quality, with beneficial or toxic effects on human and animal nutrition, provide resistance to biotic abiotic stresses. While the distribution these compounds has been described in leaves roots tissues, very limited information is available about spatio-temporal accumulation seeds model crop plants. Camelina sativa (camelina) an oilseed cultivated for industrial uses. we previously explored detail SM plasticity, no expression SM-related proteins genes camelina seeds. In this study used untargeted metabolomics (LC-MS/MS), proteomics (DIA) transcriptomics (RNA-Seq) analyse synthesis, transport, modifications degradations SMs are accumulated different seed tissues (i.e. coat, endosperm, embryo) at 6 developmental 2 germination stages. Our results showed specific patterns many SMs, related genes, during coat embryo development. We also that, differently from Arabidopsis thaliana seeds, defence antinutritional glucosinolates were both corresponding degradation products isothiocyanates present high level embryos dry C. . Characterizing spatial dynamics will contribute development crops optimized quality nutrition.
