From: A new experimental approach for studying bacterial genomic island evolution identifies island genes with bacterial host-specific expression patterns

Figure 1

The S. typhimurium genomic island STM4305 region. A map of the S. typhimurium genomic island STM4305 region is depicted. The arrows (both open and black) indicate the genes of the region that have been cloned onto R995 using VEX-Capture. The black arrows indicate genes or operons whose expression has been analyzed using RT-PCR or lacZ reporter assays in this study. The genes that comprise island STM4305 are indicated by a bracket below the map. The STM gene number is indicated below each gene. Underlined STM numbers indicate the genes to which primers were designed for RT-PCR analysis. The brackets above the diagram indicate intergenic sections that range in size from 265 to 1658 base pairs and are likely promoter regions. All other regions between the bold arrow genes range in size from -7 to 84 base pairs (except for a 248 bp region between STM4318 and 4319). Note that STM4311, which is present in the sequenced S. typhimurium strain LT2, is not present in strains χ3339 and UK1 (see text and Figure 2. The pheU tRNA gene (STM4321) is indicated as an open box.
