โœฆ Synopsis

The permeability of the plastid envelope during the development of Arena saliva plastids was investigated by light scattering and uptake of various labelled compounds (malate, succinate, glutamate, c~ketoglutarate, citrate, glycine, sucrose). The results presented show that a primary event during greening is a change in permeability, thereby allowing an in- creased transport of metabolites across the membranes of very early etio-chloroplast stages. The results are discussed in view of an adaption of the plastid envelope permeability to the changing requirements of externally synthesized precursors and intermediates during development.
