FIG. 2.

Seven transposon insertions in non-dot/icm genes that suppress the lethality caused by loss of dotL were isolated. The insertions were found in five genes, i.e., ldsB, cpxR, yitW, ldsA, and djlA. A map of the region surrounding the site of the insertion(s) is shown, with the gene responsible for suppressing ΔdotL lethality indicated with gray arrows, the genes surrounding the site of insertion indicated with white arrows, and the sites of the transposon insertions shown with vertical black arrows. For each strain, the ability of the dotL⁺/ΔdotL::Cm^r merodiploid to resolve to the ΔdotL::Cm^r locus is indicated in the far right column, with the frequency of ΔdotL mutant recovery normalized to the ΔdotA strain JV1005 (100%).
