Abstract
This disclosure describes, in one aspect, a cell that includes a biocontainment system. Generally, the biocontainment system includes a coding region whose overexpression decreases growth of the cell, a transcription regulatory region that includes a silent mutation and is operably linked upstream of the coding region, and a polynucleotide that encodes a programmable transcription activator engineered to bind to the transcription regulatory region in the absence of the silent mutation. Thus, in the absence of the silent mutation, the programmable transcription activator induces overexpression of the coding region; in the presence of the silent mutation, the programmable transcription activator does not initiate overexpression of the coding region.
