Plasticity of photorespiratory activity in Arabidopsis thaliana in response to nitrogen (B04)

• Subject Area: Plant Physiology
• Term: since 2024
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 512328399

B4 (Fernie, Nikoloski) studies plasticity in photorespiration to variation in nitrogen availability. Photorespiration recycles the toxic product from the oxygenation reaction of RubisCO into the central carbon metabolism; it is thus wasteful, but also essential. The rate of photorespiration is plastic to nitrogen availability. The project will combine high-throughput metabolite measurements and refined constraint-based computational modelling to estimate photorespiratory fluxes across a panel of Arabidopsis accessions grown in a range of environments. Based on this, plasticity genes will be identified and functionally analysed.
