Fine-structure mapping of the rts, rplK, rplL, and rpoB genes of Escherichia coli

Abstract
The specialized transducing phage .lambda.cI857S7drifd18 was used as a donor in a transductional mapping of 4 genes in the rif region of the E. coli genome. The gene order was rts-2.9-rplK-1.4-rplL-0.8-rpoB, where the numbers indicate intermarker distances in kilobases. The possible orientation of these genes with respect to each other and to neighboring genes is discussed.
