Metabolomic Responses of Arabidopsis Suspension Cells to Bicarbonate under Light and Dark Conditions.

ABSTRACT: Global CO₂ level presently recorded at 400 ppm is expected to reach 550 ppm in 2050, an increment likely to impact plant growth and productivity. Using targeted LC-MS and GC-MS platforms we quantified 229 and 29 metabolites, respectively in a time-course study to reveal short-term responses to different concentrations (1, 3, and 10 mM) of bicarbonate (HCO₃^-) under light and dark conditions. Results indicate that HCO₃^- treatment responsive metabolomic changes depend on the HCO₃^- concentration, time of treatment, and light/dark. Interestingly, 3 mM HCO₃^- concentration treatment induced more significantly changed metabolites than either lower or higher concentrations used. Flavonoid biosynthesis
