Transduction analysis using leucine requiring mutants ofSalmonella typhimurium

Abstract

1. Data is presented in support of the hypothesis that inSalmonella typhimuriumthe fragments participating in the transduction of a particular linkage group arise by breakages at constant positions in the genome of the donor bacteria.2. Data from three factor transduction experiments are used to construct a linkage map of theleu-araBregion which defines not only the relative order of the markers but also the relative distances between them.
