title: A mutation of Streptomyces lividans which prevents intraplasmid recombination has no effect on chromosomal recombination.
abstract: A mutation (rec-46) of Streptomyces lividans, previously shown to prevent (or greatly diminish) homologous and illegitimate intraplasmid recombination, was shown to have no effect on generalised chromosomal recombination occurring in matings or in protoplast fusions, nor to affect homologous recombination between a recombinant plasmid and the host chromosome. By comparison with Escherichia coli mutants defective in various aspects of recombination, the rec-46 mutation is similar to those in recF, recJ, recO and topA.
