Engineering organisms resistant to viruses and horizontally transferred genetic elements

Patent ·
OSTI ID:1859963

Organisms resistant to horizontal gene transfer (HGT), and compositions and methods of use thereof are provided. The organisms are typically genomically recoded organisms (GRO), typically cells, having a genome in which at least one endogenous codon has been eliminated by reassignment of the codon to a synonymous or non-synonymous codon. The GRO typically include a recombinant expression construct for expression of at least one element of a ribosomal rescue pathway, typically lacking the eliminated codon. Typically, the disclosed cells are resistant to completed transfer and/or expression of a horizontally transferred genetic element (HTGE) from another organism compared a corresponding cell having a genome wherein the eliminated codon has not been eliminated. In some embodiments, the organism from which the HTGE is being transferred is a bacterium or a virus.
