technologyreview – People are arguing about whether genetically modified foods should carry labels. But the next generation of GMOs might not only be unlabeled—they might be unregulated.
Over at Scientific American you can read a 6,000-word story about how one such organism, a GM mushroom, was created. The short version is that a plant scientist named Yinong Yang used the gene-editing technique called CRISPR to snip out a few DNA letters in the genome of “Agaricus bisporus, the most popular dinner-table mushroom in the Western world.”
The result: he turned off an enzyme that turns mushrooms brown.
