The kinetic complexity of Acetabularia chloroplast DNA
Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1978The kinetic complexity of Acetabularia cliftonii chloroplast DNA is 1.52 +/- 0.26 . 10(9) daltons, compared to 0.2 .10(9) daltons for Chlamydomonas chloroplast DNA. There is an average of three genomes per chloroplast. The unusually large size of the Acetabularia genome may reflect the ancient evolutionary history of this organism.

Distribution of DNA in dividing spinach chloroplasts
Nature, 1974SPINACH chloroplasts, like other higher plant chloroplasts, contain DNA1 and divide2. It has been estimated3–5 that chloroplasts contain many copies of DNA, but in higher plants, which contain large numbers of chloroplasts per cell2,6 it is not known when the DNA of chloroplasts replicates and how it is distributed when they divide.

Inhibition of chloroplast DNA synthesis by cycloheximide
Journal of Molecular Biology, 1971Abstract Cycloheximide, a potent inhibitor of cytoplasmic, but not chloroplast, protein synthesis, inhibits tobacco chloroplast DNA synthesis. Chloramphenicol, an inhibitor of chloroplast but not cytoplasmic protein synthesis, has no effect on chloroplast DNA synthesis.

We had previously reported the isolation of circular chloro-plast (et) DNA molecules from pea leaves. Circular pea ctDNA was found to have a molecular weight of 90×106 with no evidence of inter- or intramolecular heterogeneity. Recently we have extensively studied the size and structure of ctDNAs from pea, bean, spinach, lettuce, corn, and oats.2 As ...

DNA Labeling by Isolated Wheat Chloroplasts
2003In wheat, growth is from a basal meristem: The cells of the young shoot form a developmental array from the tip (oldest) to the base (youngest) of the leaf. In cells from a specific part of the leaf (and so of a certain age), chloroplast DNA is found to be replicating. In seedlings up to 10 d old, chloroplast DNA replication is found in the region from

Isolation and Structural Analysis of Chloroplast DNA
1986Publisher Summary This chapter describes a filter hybridization approach for mapping chloroplast DNA (cpDNA) restriction sites along with several strategies for generating restriction fragments for use as hybridization probes. Approaches for visualizing and mapping cpDNAs that are difficult or impossible to isolate in very pure form are also ...
