Induction of Barnase (death gene) reduces cell growth
This contruct works by expressing background levels of Barstar with Barnase inducible such that it will overwhelm Barstar when induced. Higher levels of Barnase expression resulted in lower rates of growth in the bacteria, affirming the principle of Barnase-based growth control for the genetic fence, and confirming the results from Berkeley 2008. We characterized the growth repression of Barnase under a range of arabinose inducer concentrations.
Our results show that expression of Barnase is effective in reducing cell growth, suggesting that Barnase will enable the genetic fence to prevent growth of iGarden plants outside of their designated areas.
