The second wave involves producing plants with qualityadded characters that would increase agronomic efficiency (e.g., salttolerant tomatoes) or nutritional enhancements (e.g., highlysine corn). Highlysine corn is more palatable and significantly more digestible than Pharming refers to the use of genetic engineering to Pharming
