Sequence Homology between Chloroplast DNAs from Several Higher Plants.
An estimate has been made of the amount of sequence homology present in the chloroplast DNA (ctDNA) of several higher plants by the technique of DNA-DNA hybridization. Approximately 85% of tomato, 60% of spinach, 45% of kale, and 15% of barley ctDNA sequences were found to hybridize with tobacco ctDNA under conditions in which maximum hybridization in homologous reactions reached 85%. All heter...
متن کاملNucleotide Sequence Homology Exists between the Chloroplast and Nuclear Ribosomal DNAs of Euglena gracilis.
The nuclear and chloroplast ribosomal DNAs from Euglena were shown to have specific regions of nucleotide sequence homology. The regions of homology were identified by hybridization of restriction endonuclease DNA fragments of cloned chloroplast and nuclear ribosomal DNAs to one another. The regions of homology between these two ribosomal DNAs were in that part of the genes that code for the 3'...
متن کاملDistinction between Nuclear Satellite DNAs and Chloroplast DNA in Higher Plants.
Triton X-100 solubilized chloroplast DNA but not nuclear DNA from a mixture of chloroplasts and nuclei. The buoyant density of chloroplast DNA was different from that of the satellite DNA in all of the species examined (Phaseolus coccineus, Cucumis sativus, Cucumis melo, Antirrhinum majus, Vicia faba, Oenothera fruiticosa youngii). Chloroplast DNA constituted between 4.3% and 0.25% of the total...
متن کاملConservation of sequence arrangement among higher plant chloroplast DNAs: molecular cross hybridization among the Solanaceae and between Nicotiana and Spinacia.
Isolated, nick-translated Pvu II fragments of Nicotiana tabacum chloroplast DNA produce specific intra- and intergeneric hybridization signals with chloroplast DNA digests from several representatives of the Solanaceae. These data, along with similarities in restriction enzyme patterns, permit construction of physical maps for Nicotiana line 92 (a cytoplasmic substitution line), Atropa belladon...
