Module 2: What is gene editing and how does it differ from other crop breeding techniques?

Gene editing (also known as genome editing and sometimes referred to as precision breeding) is a technology that allows breeders to make precise, targeted changes to the genetic code (DNA) of plants or animals. It can be used to introduce beneficial new traits such as resistance to pests and diseases, improved nutritional value and climate resilience. 

Gene editing can be much faster than conventional breeding techniques, which can take decades to achieve the same results, and it differs from genetic modification (GM) in that foreign DNA does not need to be present in the resultant plant or animal. In addition, it allows the creation of genetic changes that could happen naturally or as a result of “traditional” breeding methods, resulting in gene edited plants/animals that are indistinguishable from non-gene edited counterparts.
