Advocates claim that synthetic biology and the so-called New Breeding Techniques (NBTs) are distinct from genetic engineering (GE), write Helena Paul, Elisabeth Bücking & Ricarda Steinbrecher.

The 'new GE' techniques - as they should be named - and their products deserve regulation at least as strict as those applying to GMOs.
