Essential nucleoid proteins in early chloroplast development
Trends in Plant Science, 2013The plastid transcription machinery can be biochemically purified at different organisational levels as soluble RNA polymerase, transcriptionally active chromosome, or nucleoid. Recent proteomic studies have uncovered several novel proteins in these structures and functional genomic studies have indicated that a lack of many of these proteins results ...

Changes in envelope permeability during chloroplast development
Planta, 1976The 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 ...

Nuclear Genes Controlling Chloroplast Development
1980We are interested in defining the controls of plastid differentiation in Zea mays L., a C4 plant containing dimorphic mesophyll and bundle sheath plastids as well as chromatoplasts, amyloplasts and proplastids in meristematic zones. One approach’ is to examine normal plastid developmental pathways at the light and electron microscope level and by ...

Evolutionary Aspects of Chloroplast Development
1984Life began nearly 3.8 billion years ago, within a remarkably short time after formation of the earth. The rapidity in the appearance of living structures raises the possibility that this event could have happened more than once. Nevertheless, the near universality of the genetic code can be explained most directly by assuming that all current genomes ...
