🎧 Genome editing and the future of food

Episode summary: Dan Saladino looks at the future role of genome editing in food and farming. A public consultation is underway on technologies such as CRISPR. What could it mean for farmers and consumers? Unlike transgenic technologies (in which DNA is moved from one species to another), genome editing can be used to create changes to the DNA of plants and animals within a species. Helping to explain how the technology works is a plant biologist working at Cold Spring Harbour in the United States, Zach Lippman. He’s using CRISPR to create new types of tomato plants, some of which are higher yielding, more compact and better suited to urban agriculture. Meanwhile, Dr Mike McGrew, a molecular biologist based at the Roslin Institute in Scotland describes how genome editing might help result in future breeds of chickens that are completely resistant to avian influenza, a serious problem for all forms of poultry production. The public consultation has been prompted by the UK government’s desire to change the legal status of…
