“…In contrast, the gua iacol peroxidase activity was higher under the same conditions. Of note, the higher activity of the studied antioxidant enzymes, which was due to JA influence, was also observed in other plants [14,22,23]. As was found, JA and methyl jasmonate can induce new molecular species of SOD and peroxidase in wheat and castor bean leaves [22,23].…”

As was found, JA and methyl jasmonate can induce new molecular species of SOD and peroxidase in wheat and castor bean leaves [22,23]. It is possible that a sta ble function of the antioxidant system in the JA pre treated wild type Arabidopsis plants resulted in the maintenance of the photosynthetic pigment pool under salt stress (table).…”

“…As noticed, there is evidence of lower sodium accumulation by JA pretreated plants subjected to salt stress [8], as well as oxidant system induction [23]. JA was shown to participate in the reg ulation of the syntheses of flavonoid [15] and ascorbic acid [24,25], which are involved in antioxidant func tions.…”

The effects of exogenous jasmonic acid (JA) on antioxidant enzymes in four week old leaves of wild type Arabidopsis thaliana L. (Columbia 0) and jin1 (jasmonate insensitive 1) mutant plants with defective jasmonate signaling were investigated under normal conditions and under salt stress (200 mM NaCl, 24 h). The wild type plants responded to JA by an increase in the activities of Cu/Zn superoxide dismutase, catalase, and guaiacol peroxidase, while there was no change in the case of the mutant plants. In response to the salt stress of both the wild type and mutant genotypes, the activities of superoxide dismutase, catalase, and guaiacol per oxidase were unchanged, decreased, and increased, respectively. The JA treated wild type plants showed the highest activity of all three enzymes as compared with the mutant plants. Salinity caused a decrease in chloro phyll content in the wild type and jin1 plants. Preliminary JA treatment of the Col 0 plants resulted in a normal content of photosynthetic pigments after the salt stress, while the positive JA effect was insignificant in the jin1 mutants. It was concluded that the MYC2/JIN1 protein is involved in the JA signal transduction and plant adaptation to salt stress.

“…10 -6 M, as well as JA solutions with concentrations of 10 -5 , 10 -6 and 10 -7 M were previously added to the experimental versions of the nutrient media. These concentrations were chosen by us as optimal due to the data previously obtained in our laboratory on the influence of SA and JA on the degree of development of SNB in various wheat cultivars in the pathosystem (Yarullina et al, 2011).…”

RNA interference is a gene silencing mechanism that plays an important role in genetic regulation in a number of eukaryotes. Argonaute (AGO) proteins are central to the complex RNA interference system. However, their role in this mechanism, both in the host plant organism and in the pathogen, has not yet been fully elucidated. In this work, we identified and phylogenetically analyzed the SnAGO1, SnAGO2, SnAGO3, and SnAGO18 genes of the pathogenic fungus Stagonospora nodorum Berk., and analyzed their expression under conditions of infection of plants with varying degrees of resistance to the pathogen. The expression level against the background of plant immunization with the resistance inducers salicylic and jasmonic acids was assessed. In addition, the activity of these genes in the culture of the fungus in vitro was studied under the direct influence of resistance inducers on the mycelium of the fungus. Earlier activation of the SnAGO genes in in vitro culture under the influence of salicylic and jasmonic acids suggests their sensitivity to it. In an in vivo system, plant immunization to induce the accumulation of pathogen SnAGO transcripts was found. At the same time, the SnAGO genes of the fungus S. nodorum, when interacting with plant cells, reacted depending on the degree of host resistance: the highest level of transcripts in the resistant variety was observed. Thus, our data prove that the SnAGO genes of the fungus S. nodorum effectively interact with the host defense system in direct proportion to the degree of resistance of the latter to the pathogen. It was proposed to use the ratio of the transcriptional activity of the fungal reference gene SnTub to the host TaRLI gene as a marker of disease development in the initial period of the infectious process.

“…3). It was previously shown that infection of wheat with covered smut and leaf blotch resulted in an increase in oxalate oxidase activity and the level of H 2 O 2 in plant tissues under the influence of resistance inductors [33,34]. The effect of ethylene on activity of peroxidases, the "twofold purpose" enzymes, which are involved into the generation and utilization of ROS in the pro cess of plant infection, was not studied [5,35].…”

The effect of 1 methylcyclopropene (1 MCP), which inhibits the reception of ethylene, on the following has been studied: hydrogen peroxide generation, oxalate oxidase activity, peroxidase activity, cata lase activity, and lignin accumulation in infected leaves of soft spring wheat (Triticum aestivum L.) cultivars that differ in their resistance to the leaf blotch disease, caused by the hemibiotrophic fungus Septoria nodorum Berk. A decrease in the development of leaf blotch in wheat leaves under the influence of 1 MCP was, on one hand, followed by an inhibition of catalase activity; on the other hand, it was accompanied by an increase in oxalate oxidase and peroxidase activity, as well as an accumulation of H 2 O 2 in tissues and lignin in the infected zone. The role of the ethylene reception system in the defense response of plants to infection with a hemi biotrophic pathogen, that causes leaf blotch disease, is discussed.
