Site‐specific integration of DNA into wild‐type and mutant lox sites placed in the plant genome

The bacteriophage P1 Cre-lox site-specific recombination system has been used to integrate DNA specifically at lox sites previously placed in the tobacco genome. As integrated molecules flanked by wild-type lox sites can readily excise in the presence of Cre recombinase, screening for mutant lox sit... View More
