GM maize from site-specific recombination technology, what next?

The term plant genetic engineering has long conveyed a highly efficient and precise process for the manipulation of plant genomes. For nearly two decades, research on recombinase-based applications has steadily advanced the surgical capabilities of plant genome rearrangements. Once considered interesting laboratory exercises, a first crop plant derived from this type of DNA acrobatics is heading to market. Originally configured for a specific application, to remove a selectable marker, it could be the first of more to come — and not just market-free plants.
