For (probably) the first time ever, plants modified with the “genetic scissors” CRISPR-Cas9 has been cultivated, harvested and cooked. D professor in Plant Cell and Molecular Biology served pasta with “CRISPRy” vegetable fry to a radio reporter. Although the meal only fed two people, it was still the first step towards a future where science can better provide farmers and consumers across the world with healthy, beautiful and hardy plants.
CRISPR (Clustered regularly interspaced short palindromic repeats)-Cas9 is a complicated name for an easy, but targeted, way of changing the genes of an organism. The decisive discovery was published in 2012 by researchers at Umeå University, and the “Swiss army knife of genetic engineering” has been predicted to change the world. With CRISPR-Cas9, researchers can either replace one of the billions of “letters” present in an organism’s genome (i.e. the entire gene pool consisting of DNA) or remove short segments, similar to when you edit a written text in a word processor. The technology is called “gene editing” or “genome editing.”
