Figure 1From: An investigation of horizontal transfer of feed introduced DNA to the aerobic microbiota of the gastrointestinal tract of ratsOverview of the generation of the replacement recombination vectors pM1, pM2 and pM3. The plasmids pM2 and pm3 were mixed with standard rat feed for the feeding trials. KmR; kanamycin-resistance (npt I); strepR: streptomycin resistance; gfp: gfpuv-gene (enhanced GFP) with native promoter. Figures are not to scale.Back to article page
