The work is devoted to the study of the mechanisms that reveal the effective adaptive interactions of plants with microorganisms in the rhizosphere. The team of authors for the first time systematically evaluated the soil microbiome of agrophytocenoses and its trophic functional activity. The taxonomic structure and biodiversity of prokaryotes metagenome of plants rhizosphere has been determined by the pyrosequencing method. The experiments have been conducted successfully and show the interactions in sterile plant cultures with the production of planting material and microorganisms and their preparative forms. Physiological features and specifics of corresponding reactions of model cultures to stress factors and possibility of control of the formation of plants rhizosphere concerning a complex of factors are shown.

The results of a comprehensive study of the adaptive potential of plant-microbial interactions of the rhizosphere allowed to scientifically substantiate the feasibility of combining biotechnological methods of obtaining healthy regenerating plants with biological methods of protection, in particular, the authors showed the effect of chitosan and its biologically active compositions, substances of phenolic nature and microbial preparations for morphogenesis and antioxidant potential of plants.

The authors deepen the understanding of the influence of plant root exudates on the functional structure and activity of the soil microbial complex, the intensity, and direction of the processes of microbial transformation of organic compounds in the rhizosphere; about the corresponding reactions and elicitor-induced systemic immunity of plants, which is the basis for the creation of new environmentally friendly agrobiological means for growing organic agricultural products.

The research results are of great practical importance for a wide range of facilities for the evaluation and optimization of new environmentally sound agricultural measures, as they underlie the disclosure of biological potential to increase crop productivity, as well as developing strategies for any, including highly profitable agricultural production.

Number of publications: ncluding 32 articles (5 - Scopus, 2 - Web of Science), 1 monograph, 2 guidelines, 1 patent for a utility model, and 24 abstracts. The total number of references to publications and h-index on the topic of the work: 54/3 (Google Scholar), 5/1 (Scopus).
