摘要：

Non-green plastids are important sites for the biosynthesis of starch and fatty acids, which are essential for plant development and reproduction, and have a significant role in human nutrition. Unlike chloroplasts, all the metabolites for these processes in non-green plastids have to be imported via specific transport proteins. Recent advances in unravelling the molecular structures and substrate specificities of the transporters connecting the biochemical pathways between cytosol and stroma now make it possible to develop models for metabolic fluxes in these pathways. The basic principle of adapting the transport capacities of the plastid envelope to the physiological needs of the plant is the variable production of closely related transporters with overlapping substrate specificities.
