Allergen-free GM plants may boost food safety

Significant research has focused on removing the allergens from peanuts, as these can be deadly. The science has focused on three types of proteins: Ara h1, h2, and h3. "Of these three allergenic proteins, the Ara h 2 glycoprotein is the most potent allergen, with nearly 50-fold greater potency than Ara h 1," wrote Singh and Bhalla.
Using gene silencing techniques, researchers have reported the production of peanut plants with virtually no Ara h2, said the reviewers.
