4 Genetic elements used in approved genetically modified agricultural crops - implications for screening and product-specific detection methods

Almost all approved genetically engineered crops (List of Tables: Tables 3-10) were first approved in the United States. Exceptions are the genetically modified chicory from Bejo-Zaden (ID 35), genetically engineered tobacco from Seita (ID 32) and the genetically modified carnations approved in Australia. An analysis of the genetic elements used for the generation of the 28 distinct genetically engineered agricultural crops approved in the United States and the European Community therefore represents a comprehensive basis for the development of nucleotide-based detection methods. These 28 approved products include the following crops: chicory (1), corn (6, products derived from the same transformation events such as ID 14 and ID 61 are treated as a single product in this inventory), cotton (4), papaya (1), potato (2), rapeseed (4), soybean (2), squash (2), tobacco (1) and tomato (5). For several products, plants (lines) originating from several distinct transformation events have been approved. This has resulted in minor differences in the content of certain genetic elements present in these lines. These differences are indicated by brackets (List of Tables: Tables 3-5) or by asterisks in the relevant Tables (List of Tables: Tables 16-19).
