The treatment of plants by herbicide glyphosate can affect their resistance to disease. The effect of glyphosate on the expression of pathogenesis-related and resistance genes in transgenic potato infected with two strains of late blight pathogen, Phytophthora infestans was investigated. To do so, an optimal concentration of glyphosate (1.8 mg/L) were been used on transgenic potato, Vesnianka cultivar. a high level of expression of pathogenesis-related genes (especially PR-2) and defense response genes (especially HSR-203j). In these plants, no signs of burn and infection were observed were observed in the potato leaves infected with pathogen, and treated by glyphosate. The results showed that treatment by glyphosate could help to induce the resistance to P. infestans by expressing genes encoding defense response proteins.

Plants are usually attacked by several pathogens such as fungi, bacteria, viruses and other microorganisms. Different defense pathways in plants evolved in reaction to pathogens. It has been shown that plant defense responses to pathogens can be stimulated by plant processing at optimal concentration of glyphosate. In plant genetic engineering, the study of the effects of glyphosate in terms of herbicidal, fungicidal and antibacterial properties has been used to produce weed-resistant plants and to cure some fungal and bacterial diseases of plants. It has been shown that plants treated by glyphosate can react to phytopathogens by inducing an acquired resistance system and expressing of pathogenesis related genes and defense response genes. This article, reviewing studies, showed that, the treatment of plants by glyphosate not only eliminate weeds of farmland but can also induce a systemic acquired resistance to phytopathogens, specially to fungi and bacteria by expressing of proteins and defense response genes.
