The search for effective and environmentally friendly approaches to protecting cultivated plants from pathogens is one of the most pressing areas of plant science, since pathogens often lead to significant losses in crop yields. The discovery and explanation of the phenomenon of RNA interference (RNAi), which is involved in the regulation of the activity of various genes in both the host plant and the pathogen, made it possible to evaluate the possibility of its use for practical purposes. In this work, we analyzed the activity of the Ago1, Ago2 and DCl2 genes of the RNAi system in a number of representatives of the genus Triticum L.: T. timopheevii, T. monococum and the T. aestivum variety “Salavat-Yulaev” during infection with the pathogenic fungus S. nodorum Berk. During the study, we found that the activity of the studied genes of the RNA interfering system of wheat plants actually changed under the influence of the phytopathogen. Thus, our data indicate the involvement of the protein components Ago and DCL, involved in the phenomenon of RNA interference, in the protective response of wheat plants against the phytopathogen S. nodorum.
