Publisher Summary Chloroplasts are organelles specializing in the conversion of radiant energy to chemical energy. The chloroplast is involved in photosynthesis and consequently cells that contain chloroplasts are autotrophic, which means that they are able to make their own food from inorganic molecules by using the radiant energy of sunlight.

Chloroplast Elongation Factors are Synthesized in the Chloroplast
European Journal of Biochemistry, 1979The elongation factor G (EF‐Gchl) and elongation factor Tu (EF‐Tuchl) present in spinach chloroplasts become labelled when isolated chloroplasts are incubated in the light with radioactive methionine. EF‐Gchl and EF‐Tuchl account for approximately 0.04% and 0.2% respectively of the total radioactivity incorporated by isolated organelles.

Current Opinion in Genetics & Development, 1992
New features of chloroplast gene expression are continually being discovered, particularly in the area of post-transcriptional RNA processing. RNA editing of chloroplast pre-mRNAs occurs in both monocotyledons and dicotyledons, and involves both initiator and internal codons.

The ultrastructure of chloroplasts
Experimental Cell Research, 19551. 1. On ultrathin sections of chloroplasts from Aspidistra elatior the electron microscopic study has revealed that the grana consist of layered columns. 2. 2. The grana are organized in double membrane discs the two membranes of which are about 65 A thick. These membranes bound a narrow, closed space the height of which also is about 65 A. The

IT has been concluded from experiments with barley leaves that chloroplasts contain cytochromes ƒ and b 6 and no cytochrome c 1. We have been able to extend the observations to two other widely differing species and to record certain characteristics of the cytochromes present.

Plant Molecular Biology, 1992
The chloroplast genome consists of homogeneous circular DNA molecules. To date, the entire nucleotide sequences (120-190 kbp) of chloroplast genomes have been determined from eight plant species. The chloroplast genomes of land plants and green algae contain about 110 different genes, which can be classified into two main groups: genes involved in gene

Conjugated Polymer Nanoparticles to Augment Photosynthesis of Chloroplasts.
Angewandte Chemie, 2017By coating chloroplasts with conjugated polymer nanoparticles (CPNs), a new bio-optical hybrid photosynthesis system (chloroplast/CPNs) is developed. Since CPNs possess unique light harvesting ability, including the ultraviolet part that chloroplasts ...

Dielectrophoresis of chloroplasts
Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1971Abstract Dielectrophoresis is the migration of neutral particles in a nonuniform electric field (a.c. or d.c.) toward the region of highest field intensity. Dielectrophoresis should be distinguished from electrophoresis which is the migration of charged particles in electric fields.

Isolation of chloroplasts and chloroplast DNA
1994That chloroplasts are green and therefore recognizable by eye should have been an advantage in developing methods for their isolation, but historically it has been a disadvantage. It was relatively easy to grind up cells, subject the brei to differential centrifugation, and obtain a green pellet.

THE ELECTROPHOTOLUMINESCENCE OF CHLOROPLASTS
Photochemistry and Photobiology, 1976Abstract— Delayed light emission emanating from preilluminated chloroplasts can be perturbed with pulsed DC electric fields (200–4000 V cm‐1), The perturbation produces a strong stimulation of chlorophyll luminescence. During the field perturbation the stimulated emission rises to a maximum, typically within 100μs. and then decays.
