Figure 5. Qrr1 shows different capabilities in regulating multiple targets.
Fluorescence from plasmid-encoded V. harveyi AphA-GFP (pYS069; (A)), LuxR-GFP (pYS141; (B)), LuxO-GFP (pYS142; (C)) translational fusions were measured in E. coli MC4100 carrying an empty vector (pRHA109), a vector expressing a rhamnose-inducible qrr1 gene (pYS122) or qrr4 gene (pSTR0227). GFP from three independent cultures was measured for each strain and the means and SEMs are shown.
