Replacement found for bacterial DNA in transgenic crops

Possible spread of antibiotic resistance to gut bacteria squelched by using weed genes.

Scientists may have developed a potentially less controversial way to bioengineer plants, by replacing a marker gene normally borrowed from bacteria with a gene from weeds. The new technique could make genetically modified crops less contentious in places such as Europe, the team says.
