A gene-edited version of edible Agaricus bisporus mushrooms (unedited mushroom shown) doesn’t need to be regulated as a genetically modified crop, agriculture officials say.
A mushroom whose genes have been edited with molecular scissors known as CRISPR/Cas9 doesn’t need to be regulated like other genetically modified crops, the U.S. Department of Agriculture said April 13 in a letter to the mushroom’s creator. The edible fungus is the first CRISPR-edited crop to clear USDA regulation.
SUMMARY: "On Halloween, AquaBounty, the company that wants to feed you genetically engineered salmon, saw its fortunes change. A well-connected biotech company called Intrexon swooped in to buy around half the stock of the near-bankrupt AquaBounty. Intrexon is run by the former head of Monsanto and a former vice-president from Pfizer and McDonalds. Intrexon’s senior vice president and animal science head is Thomas Kasser, a 20-year veteran from Monsanto, where he worked on recombinant bovine growth hormone (rBGH).

University of Maryland entomology professor Raymond St. Leger has discovered how to use scorpion genes to create a hypervirulent fungus that can kill specific insect pests, including mosquitoes that carry malaria and a beetle that destroys coffee crops, but does not contaminate the environment as chemical pesticides do.

26/06/2007- The simple, run-of-the-mill, salad-variety mushroom has upped its super powers to become a potential future disease-busting hero, according to US researchers.
A genetic modification is all it would take for the common button mushroom (Agaricus bisporus) to become the new Superman as a therapeutic protein-producing factory, taking the wind out of conventional cell lines.

FOR the first time, a fungus has been genetically modified to be more deadly
to the weed it blights. The snag is that the GM fungus kills crop plants as
While the modified fungus will not be released as a result of the findings,
the case shows how genetic modification can have unintended consequences. It
is also proof, were any needed, that biotechnology could be harnessed to
create weapons that attack crops (see "'Act now' plea on bioterror threat").
