title: [Chloroplast DNA cloning in Escherichia coli. II. The properties of the recombinant plasmids bearing the EcoRI fragments of pea chloroplast DNA and the cloning of the DNA sequences with rRNA genes].
abstract: Previously a method of selection of colicine-defective recombinant plasmids by mitomycin C was described. A series of recombinant plasmids (CPS) with various EcoRI-fragments of pea chloroplast DNA has been obtained. This paper describes some properties of cloned fragments replicated in Escherichia coli. The alkali stability of recombinant plasmid DNAs has been demonstrated, indicating the absence of ribonucleotides in their structure. Heterogeneity of chloroplast DNA in nucleotide composition was demonstrated using ultracentrifugation analysis of CPS-plasmid DNAs in CsCl-actinomycin D density gradient. Pea chloroplast rDNA was cloned in recombinant plasmids.
