Isolation of chloroplasts and chloroplast DNA

1994
That 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, 1986
The 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 chloroplast DNAs of flax genotrophs

Plant Molecular Biology, 1982
The 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.

The demise of chloroplast DNA in Arabidopsis

Current Genetics, 2004
Although 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.

Chloroplast DNA inheritance in Populus

Theoretical and Applied Genetics, 1992
The 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.

DNA Biosynthesis in Chloroplasts

Journal of Experimental Botany, 1988
Utilisation d'une nouvelle methode d'extraction de l'ADN (precipitation de proteines par la chaleur) pour etudier l'ADN chloroplastique. Influence du vieillissement, de la lumiere, des ions metalliques et des adenylates sur l'incorporation de thymidine ...

Nicotiana chloroplast genome III. Chloroplast DNA evolution

Theoretical and Applied Genetics, 1982
Nicotiana 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 ...

isolation of Wheat Chloroplasts and Chloroplast DNA

2003
Chloroplasts 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.

Chloroplast biosystematics: Chloroplast DNA as a molecular probe

Biosystems, 1985
The 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.

Hybridization of bean chloroplast transfer RNAs to chloroplast DNA

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1976
Bean (Phaseolus vulgaris) chloroplast tRNAsLeu and tRNAsPhe hybridize to chloroplast DNA, whereas the corresponding cytoplasmic tRNA species do not, suggesting that chloroplast transfer RNAs are coded for by chloroplast DNA. The hybridization of the three chloroplast tRNAsLeu or of the two tRNAsPhe isoacceptors is not additive, and the isoacceptors ...
