VirA/G reporter device mRFP
This BioBrick contains a complete VirA/G receptor system with an mRFP (BBa_E1010) under the control of a vir promoter as reporter gene.
Input: acetosyringone
Output: expression of mRFP
Usage and Biology
This BioBrick is for testing, characterizing and measuring the VirA/G signaling system. This system contains an unmutated virA, so it is possible to measure how the natural VirA/G system works and reacts. It is also possible to determine the basal transcription of the vir promoter and its activity after inducing the system with acetosyringone.
