ABSTRACT
Breeding for chemical modifications in crops has been practiced for a long time. The modern era brought the right breakthrough, namely by the development of chemical screening techniques. Crop plants are increasingly used for various industrial applications. Future plants will be used as factories for vaccines and pharmaceuticals. Immunizing mice with transgenic potatoes, accumulation of micronutrients or ferritin (important iron storage) in cereals, overexpression of cystein-rich metallothionine-like proteins in rice, cholera vaccines from banana, Pak-choi salad with enriched content of antioxidants, or production of nonallergenic seed albumins, are only a few examples of this branch of breeding.
