infection). Peanut
allergy is a potentially life-threatening and lifelong food allergy.
Research to date suggests some genetic variation, such as an Indonesian
germplasm lacking the protein
Ara h 1
, within peanut germplasm.
Knocking out the genes for the allergenic proteins, using TILLING or
RNAi approaches, has shown promise to derive mutants or transgenic
events lacking allergenic seed proteins. Eliminating seed protein aller-
gens will be a challenge as it is impossible to determine which ones or
how many of them can be eliminated without sacri
cing seed quality or
viability. It is encouraging to note the success of producing a few
transgenic events lacking allergenic proteins with no adverse effect
on seed quality or viability. Such genetic stocks when available to
researchers and crossed with other germplasm with high oil content,
improved fatty acid pro
les, and high Fe and Zn grain contents may lead
to the development of agronomically superior and nutritionally
enhanced peanut cultivars that are also free from toxin and allergens.
