CRISPR is a precise method of gene editing that allows for specific genes to be targeted and modified. In this case, the gene for the enzyme that causes browning was inactivated through CRISPR. Gene gun, gene therapy, and vectoring may also be methods of genetic modification, but they are not the most precise methods for inactivating a specific gene. Radiation breeding is a method of inducing mutations in plants using radiation, but it is not a targeted gene editing approach like CRISPR.
