Resistance Against Biotic Stresses

Biotic stresses have been responsible for serious losses in crop yields. The plant protection practices that have been used in the past to protect crops from these losses have reached a pollution level, which has became a major concern for environmentalists.

Therefore, production of crops resistant to biotic stresses including weeds, insects, viruses and other pathogens was the first priority .in crop biotechnology. Significant benefits have already been derived from commercialization of these crops that are resistant to biotic stresses. Major benefits in USA alone are estimated to be billions of dollars every year.
