title: A restriction map of the ribosomal RNA genes and the short single-copy DNA sequence of the pearl millet chloroplast genome.
abstract: The chloroplast rDNA genes of pearl millet (Pennisetum americanum) have been cloned and physically mapped. The chloroplast genome of the pearl millet contains two identical rRNA genes located on DNA sequences that are inverted with respect to one another and separated by 12 kb of single-copy DNA. The rRNA genes were positioned on a restriction endonuclease map by using as hybridization probes specific cloned rDNA sequences from the chloroplast DNA of the alga Euglena gracilis. The 16S and 23S rRNA genes were shown to be approx. 2 kb from one another, and the 5S RNA gene is immediately adjacent to the 23S tRNA gene.
