Compartmentation of Plant Metabolism

Similar to other higher organisms’ plants consist of different organs comprising different cell types. The metabolic requirements of a particular cell depend on its function and therefore, the metabolic environment of these cells differs. Although knowledge about the function and regulation of metabolic pathways rises, the cell-specific adaptation of metabolism is still a neglected field in plant research. Our current research focusses on serine biosynthesis in plants. Serine can be synthesised by two pathways in plants: the photorespiratory pathway in autotrophic cells and the phosphorylated serine biosynthesis pathway (PSBP) in heterotrophic cells (Benstein et al., 2013; Ros et al., 2014). Our main interest is to understand how the function of both pathways is coordinated and to what extend both pathways are interacting or independent.
