Streptomycin or spectinomycin treatment of an E. coli strain, carrying the strR and spcR alleles on the chromosome and the wild-type (sensitive) alleles on the episome, selects for inactivation of the relevant sensitive allele. After Mu induced mutagenesis, in the absence of selection against extend

A mutant of Escherichia coli which was isolated for temperature-sensitive growth was found to harbour a structural alterations in protein S16 (Isolo et al., 1978). The mutation was localized by matings with various Hfr strains and by Plkc-mediated transduction. The results showed that it mapped very
A mutant of E. coli selected for temperature-sensitive growth on rich medium harbored an altered ribosomal protein S6 (Isono et al., 1976). This mutant was found to possess at least two mutations, one being responsible for the temperature-sensitivity and the other for the S6 alteration. Crosses with
Specialized transducing phages carrying segments of the Escherichia coli chromosome from the rbs-ilv region including rrn genes have been isolated. These phages carry rrn transcription units coding for 16S and 23S rRNA with the direction of transcription clockwise towards the ilv operon. While one o
