Fig. 2From: Regulation of bacteria population behaviors by AI-2 “consumer cells” and “supplier cells”The plasmid used for the construction of reporter cells. The structure of lsr operon was depicted in the picture. The lsr is a bidirectional promoter. Three elements: lsr promoter, gfp, rrnB T1 terminator were ligated to pTrcHisB so that the plasmid pLGFP can respone to the intrecellular AI-2-P concentrationBack to article page
