As inferred from another study on tobacco GTI-antisense plants lacking measurableGNTI activity despite almost wild-type-like CCD patterns on immunoblots [43], GNTI islikely suppressed below detection limits in our potato and tomato GTI-RNAi lines.CCD-reduced foodstuff therefore provides the possibility to improve allergy testingwith whole extracts. This evidence concerns the gene MGAT1 and allergic disease.
