Biotechnology and the soybean.
Glyphosate-tolerant soybeans (GTSs), the first biotechnologically improved soybeans to be marketed, became available commercially in 1996. The safety of GTSs was assessed in 2 ways: study of the introduced protein and of the soybean seed and selected processing fractions. Because soybeans are a major source of protein in most farm animals' diets, animal feeding studies in wholesomeness were done to complement the analyses. Analysis of the expressed protein in GTSs [3-phosphoshikimate 1-carboxyvinyltransferase (EC 2.5.1.19)] showed it to be readily digestible and to possess no allergenic concerns. In addition, comparison of the composition of seeds and selected processing fractions from 2 GTS lines with the parental line showed that the lines are equivalent. Feeding studies in various animal species confirmed that the feeding value of GTS lines is comparable with that of the parental line. These studies support the conclusion that GTSs are as safe and nutritious as traditional soybeans marketed currently and can be incorporated safely into feed and food products in the near future.
