Projekt
Phenotypic plasticity of the diurnal pattern of starch metabolism in response to a fluctuating environment in Arabidopsis thaliana (B07)
Subject Area
Plant Physiology
Term
since 2024
Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 512328399
B7 (Fettke, Töpfer) will investigate the plasticity of starch metabolism to variation in nitrogen availability and to day length. Plants synthesize transitory starch during the day and degrade it at night to sustain metabolism, including nitrogen assimilation. The project will determine reaction norms for starch-metabolism traits for Arabidopsis accessions in response to different nitrogen levels and to differences in day length. Descriptors of these reaction norms will be used as phenotypes in quantitative-genetic analysis, and a kinetic model of starch metabolism will quantify the contribution of different starch-related parameters to this metabolic plasticity.
