The plant metabolome is sensitive to variations in the growth environment, as evidenced by metabolomic profiling. Changes in the levels of specific metabolites can be quantified via high-resolution magic angle spinning (HR-MAS) nuclear magnetic resonance (NMR) spectroscopy and can help identify key meta-bolic pathways related to environmental stress. We study here the metabolic response of wheat seeds to fungicidal stress during germination. A delay in ger-mination and a decrease in percentage germination were observed for fungicide-treated seeds. Our work validates the use of HR-MAS NMR spectroscopy as a novel method to gain quantitative information about the influences of micro-stresses on nutritional back-grounds in plants.
