Figure 8

Expression of PR 4315 lacZ construct in S. typhimurium and other Gram negative hosts. The STM4315 promoter region (PR 4315) was subcloned and transcriptionally-fused to a promoterless lacZ gene on a broad-host-range plasmid and assayed for beta-galactosidase expression in the indicated S. typhimurium strains and other Gram negative hosts. The results are given as a beta-gal expression ratio as indicated in the Y-axis label and in the Materials and Methods.
