Duplications of histidine transport genes in Salmonella typhimurium and their use for the selection of deletion mutants.
We demonstrate that tandem duplications of the histidine transport operon can be selected by requesting elevated levels of transport activity to be present. Several strains were constructed which contain duplications heterozygotic for either hisJ, hisQ, or hisP. The size of one duplication which was...
