[The effect of salicylic and jasmonic acids on the activity and range of protective proteins during the infection of wheat by the septoriosis pathogen].

The influence of salicylic (SA) and jasmonic (JA) acids as signaling systems mediators on the generation of H2O2 and expression of genes encoding protective proteins was studied in the leaves of wheat Triticum aestivum L. upon infection with the pathogen of septoriosis Septoria nodorum Berk. It was found that presowing treatment of seeds with SA and JA decreased the development of the fungus on the leaves of wheat and had a stimulating effect on the production of H2O2 in the area of infection.

[Comparison of the transcriptional activity of protective protein genes in different wheat cultivars infected with Septoria nodorum Berk].

A comparison was performed with respect to the transcriptional activity of protective protein genes (peroxidase TC 151917, oxalate oxidase AJ556991.1, and proteinase inhibitor EU 293132.1) in five wheat cultivars (Omskaya 35 and 36, Simbirka, Bashkirskaya 26, and Kazakhstanskaya 10) infected with Septoria nodorum Berk, which causes septoria disease.

[Activity of protective proteins in wheat plants treated with chitooligosaccharides with different degrees of acetylation and infection with Bipolaris sorokiniana].

The influence of chitooligosaccharides (COS) with different degrees of acetylation (DA) on the production of hydrogen peroxide (H2O2) and changes in the level of gene expression of pathogenesis-related (PR) proteins (oxalate oxidase AJ556991.1, peroxidase TC 151917, chitinase AV029935L, proteinase inhibitor EU293132.1) in the roots of the wheat Triticum aestivum L.

[Relationship between the aggressiveness and catalase activity of Septoria nodorum berk. in wheat].

A comparative study of hydrogen peroxide (H202) generation, the character of a fungal catalase gene expression, and the catalase activity in wheat plants, infected with Septoria nodorum Berk. strains differing in their aggressiveness, has been carried out. The decreased intensity of H202 accumulation in infected tissues, influenced by an aggressive S.

[Salicylic and jasmonic acids in regulation of the proantioxidant state in wheat leaves infected by Septoria nodorum Berk].

Influence of mediators of the signal systems of salicylic (SA) and jasmonic (JA) acids and their mixture on reactive oxygen species' (ROS) (superoxide radical O2*- and H2O2) generation and activity of oxidoreductases (oxalate oxidase, peroxidase and catalase) in leaves of wheat Triticum aestivum L. infected by Septoria leaf blotch pathogen Septoria nodorum Berk. has been studied.
