title: Reiterated DNA sequences in a mutant strain of Streptomyces glaucescens and cloning of the sequence in Escherichia coli.
abstract: Streptomyces glaucescens exhibits a high degree of genetic instability. A sequence of 7.2 kb has been found which is present in a few tandemly repeated copies in the wild type strain GLA 0 and is amplified to ca. 500 copies per genome in the mutant strain GLA 1204. This sequence was cloned in Escherichia coli using pBR325 as vector.
