Highlights•18O-water incorporation into specific acyl-CoAs unambiguously indicates β-oxidation•Fatty acid synthesis and oxidation occur concurrently during oilseed development•Substantial oxidation, comparable to germinating seedlings, initiates early in seed filling•β-oxidation occurs the day night is a regular aspect of cellular metabolismSummaryPlant lipids are an essential energy source for diets sustainable alternative petroleum-based fuels feedstocks. Fatty breakdown germination crucial seedling establishment but unexpected filling. Here, we demonstrate that simultaneous biosynthesis degradation fatty acids begins continues across all phases oil filling throughout photoperiod. Tests camelina, rapeseed, engineered high-oil tobacco line confirmed concomitant oil-producing tissues over development rule rather than exception. Furthermore, show transgenics, designed elevate biosynthesis, failed achieve anticipated increases storage lipid levels due increased degradation, potentially explaining underperformance lines compared expectations more generally.Graphical abstract
