In a plant cell the redox reactions involved in the photosynthetic assimilation of CO2 and nitrate are located in four different compartments; the chloroplast stroma, the mitochondrial matrix, the peroxisomal compartment and the cytosol. The present report deals with the question in which way redox equivalents can be transferred between these different compartments and how the redox processes in the various compartments can be coordinated. The experiments shown in the following have all been carried out with spinach leaves grown in hydroponic culture in a 9 h light 15 h dark cycle.
