Design Notes

  • The virA gene is under the control a medium strong constitutive promoter so there is enough VirA receptor expressed but not too much so the cell suffers from the expression (VirA is a membrane protein)
  • The virG gene is mutated so it works without an rpoA subunit from Agrobacterium tumefaciens ([http://www.springerlink.com/content/wmq06kua5qkma1au/ YC Jung et al., 2004])
  • Double terminator (forward) to keep expression of mRFP by the constitutive promoter low.
  • mRFP gene to show the activity of the vir promoter.
  • This BioBrick is for measuring the natural VirA/G system.
