American scientists have identified a peanut gene whose protein code opens up the possibility of producing allergen-free nuts.

Researchers from the University of Florida report in the journal Plant Science that they discovered a gene protein that shows no apparent allergic effects when tested in the blood of peanut-sensitive patients.
The identification of the protein, which is apparently unable to bind to immunoglobin, may lay the foundations for producing a hypoallergenic peanut by silencing the other major allergens in peanuts by mutational breeding or though genetic modification.
Researchers agree that a significant amount of further research is required, and that no less a challenge will be consumer acceptance over any method of product development that will likely include genetic modification.
Roughly 1.5 million Americans suffer from a severe allergy to peanuts.
