 As a result of this, technologies have been developed to remove the selectable antibiotic resistance gene marker.One such technology that has been implemented is the Cre/lox system, where the nuclear encoded Cre recombinase can be placed under control of an inducible promoter to remove the antibiotic resistant gene once homoplasmicity has been achieved from the transformation process.A recent example of transplastomics in agricultural applications was conferring potato plants protection against the Colorado potato beetle.
