The results of our study showed that; out of 25 positive soy and maize products, 15 were negative for the nos terminator while positive for the CaMV 35S promoter (six soy containing, nine maize containing products). As mentioned by many researchers the CaMV 35 S promoter derives from cauliflower mosaic virus and so plants from the Criciferae group (cauliflower, cabbage, broccoli oilseed rape, mustard and other criciferous plants) can be infected.
