Resistance induction in crop plants against insect herbivores and pathogens by elicitors

الملخص EN

Crop plants, during their Jife cycle, protect themselves against the attack of arthropod herbivores and pathogens with van nils resistance mechanisms.

jasmonate and salicylate signaling pathways arc two inducible defense responses that can protect plants against these multiple pests by ءا production and of a number of phytoehemieul؛؛ and defensive proteins such as proteinase inhibitor proteins, polyphenol oxidase and steroid glycoalkaloids as well as pathogenesis-related proteins (PR- proteins) and phytoalexins that target physiological processes ill the attacking organisms.

Secondary metabolites produced by plants in response to induction by biotic or biotic elicitors also include volatile organic compounds that attracl natural enemies of insect herbivores.

Research efforts in the area of inducible plant resistance is now being developed concerning the use of induced plant genes for insect herbivory and pathogen resistance and the potentiaf of using induced resistance (IR) or systemic acquired resistance (SAR) a environmentally safe methods of insect and disease pest control, respectively.

This paper views this research as و body to fully utilize the information in formulating future dcvcÈopment ٠٢ plant protection products and farming practices that can assist growers in controlling ^hropod herbivores and pathogen attack on high cash value plant crops.

The integration of induced host plant resistance and seniiochemieal approaches with other methods of pest management would be accepted as compatible with integrated pest management system in conventional agriculture as well as with organic farming practices.
