title: Recombination deficient mutants of Rhizobium meliloti 41.
abstract: Two mutants deficient in homologous genetic recombination have been isolated from Rhizobium meliloti 41 after Tn5 mutagenesis. Both mutants are defective in the induction of temperate phage 16-3 by UV-light, Mytomycin-C or Bleomycin, their UV sensitivity is more pronounced than that of the wild-type strain, and they lack the 'SOS activity' responsible for induced mutations.
