Input and Output Traits
There are numerous transgenes used today that code for both input and output traits. Input traits are those that potentially alter inputs needed in production. An example would be Bt corn where the need to apply a pesticide to control European corn borer is eliminated. Another example would be Roundup resistant crops that allow producers to spray Roundup for weed control without damaging crop plants. Output traits, on the other hand, are those that alter the harvested product. An example would be high-oleic acid soybeans, which have improved the product for food and industrial uses.
