Figure 8From: Analysis of a taurine-dependent promoter in Sinorhizobium meliloti that offers tight modulation of gene expression Schematics depicting integration of plasmids into the S. meliloti chromosome to generate depletion strains. Integration of (A) pJC468 or (B) pJC470 placed the only intact copy of pleC or tatB, respectively, under control of the P tauA promoter. The sizes of the regions that enabled homologous recombination are shown below each plasmid.Back to article page
