title: Distinction between Nuclear Satellite DNAs and Chloroplast DNA in Higher Plants.
abstract: 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 leaf DNA in these species, and was present as 5 to 20 copies in each chloroplast.
