title: Gene location affects expression level in Salmonella typhimurium.
abstract: Directed translocation of an expressed gene (hisD) provided strains to test for position effects on gene expression in Salmonella typhimurium. The predominant position effect seems to be caused by the gene dosage of a chromosomal site; the orientation of the translocated genes did not affect expression, and no deviant positions were found.
