Transgene-free plant breeding using genome editing
Plant geneticists from Tübingen have used genome deletion to breed a variety of tomato that is resistant to powdery mildew. The CRISPR/Cas9 technology that they used enabled them to achieve this in a relatively short period of time. They also demonstrated beyond any doubt that the new tomato variety contains no foreign DNA and is indistinguishable from naturally occurring deletion mutants.
