Identification of a Brazil-nut Allergen in Transgenic Soybeans

To improve the nutritional quality, methionine-rich 2S albumin from the Brazil nut Bertholletia excelsa has been introduced into transgenic soybeans. Soybeanns adverse health effects of genetically modified crops.

Initial studies with model plant seeds such as tobacco showed that genes encoding seed proteins with enhanced methionine content such as brazil-ntu prolamines and 2S albumins could be transferred and expressed so that these foreign proteins could contribute to the overall amino acid content.

The potential of any new food to induce allergic reactions has been seized upon by critics of GM crops, which contain foreign or engineered proteins, and has been promulgated as an easily understandable concern that could resonate with consumers.


Allergenic reactions to the storage proteins of tree nuts, sesame, sunflower, and peanuts are responsible for many scores of deaths in the US and Europe on an annual basis, with many more worldwide, but they are not as diligently recorded in the medical literature. Mabel Gracia Arnaiz 1 Estimated H-index: Hypoallergenic variants of allergenic foods have brazil-but potential to reduce the risk of adverse reactions and for less dangerous allergens this offers the prospect of permitting consumption by otherwise sensitive people.

Most of these experiments are conducted in model plants such as Arabidopsis or crop plants such as tobacco, tomato and rice with no intent for release or commercialization.

Other Papers By First Author. The proteome and immunological analysis together confirms that it is feasible to suppress an endogenous allergen without introducing adverse effects on the plant or changing the composition of the soybean seed in any way other than the removal of the targeted protein.

Imaging of the 2D gels brzail-nut over individual elements. In order to broadly apply genetic modification brazil-nyt crops, there is an urgent need for better biochemical and molecular methods, including animal models, to test for food allergens experimentally so that the supporting data can be provided to evaluate newly proposed and actual GM products.

There have been reports of using this approach to suppress an allergen in shrimp that is potentially dangerous to sensitive people, as well as other experiments to suppress the primary allergen of the domestic cat. Plant Food Protein Engineering.

FT- like genes and spike development in cereals. The most common allergenic responses are atopic reactions in transgfnic form of hives and other skin responses and gastric distress, but severe reactions allegen result in death from anaphylaxis. Much has been learned about the protein sequence epitopes of food allergens by using epitope maps constructed with overlapping short peptides encompassing the entire protein.
