title: Changes in envelope permeability during chloroplast development.
abstract: The permeability of the plastid envelope during the development of Avena sativa plastids was investigated by light scattering and uptake of various labelled compounds (malate, succinate, glutamate, α-ketoglutarate, citrate, glycine, sucrose). The results presented show that a primary event during greening is a change in permeability, thereby allowing an increased 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.
