Linkage map of Salmonella typhimurium, edition VII.

Linkage map of Salmonella typhimurium, Edition VI.

Orientation and order of loci of the met-arg region in the Salmonella typhimurium linkage map.

Salmonella typhimurium-Salmonella monteuideo hybrids were used in P22mediated transduction to obtain information about the Salmonella linkage map (GLATZER, LABRIE and ARMSTRONG 1966). Information on the orientation of the met-arg transducing fragment was included. This fragment is located between metE and metA on the linkage map (SANDERSON and DEMEREC 1965) and contains the loci m t B and F, as...

Genetic map of Salmonella typhimurium, edition VIII.

We present edition VIII of the genetic map of Salmonella typhimurium LT2. We list a total of 1,159 genes, 1,080 of which have been located on the circular chromosome and 29 of which are on pSLT, the 90-kb plasmid usually found in LT2 lines. The remaining 50 genes are not yet mapped. The coordinate system used in this edition is neither minutes of transfer time in conjugation crosses nor units r...

F-Mediated Conjugation, F Strains, and Hfr Strains of Salmonella typhimurium and Salmonella abony

Some wild-type lines of Salmonella spp. contain plasmids which are self-transmissible by conjugation (25). However, most such plasmids have very low frequencies of self-transmission owing to repression of transfer functions; this situation has been extensively analyzed by Datta et al. (6). In addition, most plasmids give infrequent chromosome mobilization because of the low frequency of plasmid...

Fine structure analysis of Salmonella typhimurium glutamate synthase genes.

Glutamate synthase activity is required for the growth of Salmonella typhimurium on media containing a growth-rate-limiting nitrogen source. Mutations that alter glutamate synthase activity had been identified in the gltB gene, but it was not known which of the two nonidentical subunits of the enzyme was altered. To examine the gene-protein relationship of the glt region, two nonsense mutations...
