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.

Transcription of the chloroplast DNA: a review
Biochimie, 1986The transcription systems of chloroplasts and bacteria share different properties. The genetic material of chloroplasts is organized in the same way as bacterial nucleoids. The regulatory DNA sequences for transcription have a strong homology with their E. coli counterparts and some regulatory mechanisms could be conserved.

The demise of chloroplast DNA in Arabidopsis
Current Genetics, 2004Although it might be expected that chloroplast DNA (cpDNA) would be stably maintained in mature leaves, we report the surprising observation that cpDNA levels decline during plastid development in Arabidopsis thaliana (Col.) until most of the leaves contain little or no DNA long before the onset of senescence.

Replication of Chloroplast DNA of Tobacco
Science, 1966An experimental method has been designed for determining the relative rates of replication of the chloroplast and nuclear DNA's of Nicotiana tabacum . By this method chloroplast DNA in week-old seedlings is being replicated several times faster than nuclear DNA.

The chloroplast DNAs of flax genotrophs
Plant Molecular Biology, 1982The chloroplast DNA of L. usitatissimum var. "Stormont Cirrus" has been mapped with respect to the recognition sites for the enzymes SalP1, Sst1 and SalG1. It is a circular molecule of about 160 kilobasepairs, with an inverted repeat containing the rDNA.

Chloroplast DNA inheritance in Populus
Theoretical and Applied Genetics, 1992The inheritance of chloroplast (cp) DNA was examined in F1 hybrid progenies of two Populus deltoides intraspecific controlled crosses and three P. deltoides × P. nigra and two P. deltoides × P. maximowiczii interspecific controlled crosses by restriction fragment analysis.

Chloroplast DNA systematics: a review of methods and data analysis
, 1994The field of plant molecular systematics is expanding rapidly, and with it new and refined methods are coming into use. This paper reviews recent advances in experimental methods and data analysis, as applied to the chloroplast genome.

Chloroplast biosystematics: Chloroplast DNA as a molecular probe
Biosystems, 1985The classification of plants has traditionally been dependent upon the comparative analysis of morphological and biochemical data. In this paper the use of molecular probe analysis of chloroplast DNA (ctDNA) is used to expand the data base used in taxonomic studies.

isolation of Wheat Chloroplasts and Chloroplast DNA
2003Chloroplasts in common with other plastids and mitochondria have their own nucleic material, in the form of multiple copies of a circular DNA molecule, normally of 120-160 kbp.

Nicotiana chloroplast genome III. Chloroplast DNA evolution
Theoretical and Applied Genetics, 1982Nicotiana chloroplast genomes exhibit a high degree of diversity and a general similarity as revealed by restriction enzyme analysis. This property can be measured accurately by restriction enzymes which generate over 20 fragments. However, the restriction enzymes which generate a small number (about 10) of fragments are extremely useful not only in ...
