Every land plant exists in a close relationship with microbial communities of several niches: rhizosphere, endosphere, phyllosphere, etc. The growth and yield of potato—a critical food crop worldwide—highly depend on the diversity and structure of the bacterial and fungal communities with which the potato plant coexists. The potato plant has a specific part, tubers, and the soil near the tubers as a sub-compartment is usually called the “geocaulosphere”, which is associated with the storage process and tare soil microbiome. Specific microbes can help the plant to adapt to particular environmental conditions and resist pathogens. There are a number of approaches to modulate the microbiome that provide organisms with desired features during inoculation. The mechanisms of plant–bacterial communication remain understudied, and for further engineering of microbiomes with particular features, the knowledge on the potato microbiome should be summarized. The most recent approaches to microbiome engineering include the construction of a synthetic microbial community or management of the plant microbiome using genome engineering. In this review, the various factors that determine the microbiome of potato and approaches that allow us to mitigate the negative impact of drought and pathogens are surveyed.

Nowadays, the development of the digital environment and the global network covers almost all spheres of life. That is why special attention is focused on the provision of the educational process with appropriate teaching aids and curricula, so that schools, universities, educators, and professional development of educators meet modern national and global challenges and provide support in the field of digital technologies, developing and shaping modern digital competencies. The article presents an analysis of digitalization in higher education and the necessity to improve the professional development of higher school educators and professional development technologies related to this process. Based on an expert survey, educational trends in the era of educational digitalization, innovative pedagogical technologies, and teaching methods are determined. The results of the survey, related to the introduction of new pedagogical and digital technologies in the educational process, allow the authors to design a model for the professional development of educators in the direction of the digital transformation of the educational process.

Rhodiola rosea L. is a valuable medicinal plant with adaptogenic, neuroprotective, antitumor, cardioprotective, and antidepressant effects. In this study, design of experiments methodology was employed to analyze and optimize the interacting effects of mineral compounds (concentration of NO₃⁻ and the ratio of NH₄⁺ to K⁺) and two plant growth regulators [total 6-benzylaminopurine (BAP) and α-naphthylacetic acid (NAA) concentration and the ratio of BAP to NAA] on the growth and the production of total phenolic compounds (TPCs) in R. rosea calluses. The overall effect of the model was highly significant (p < 0.0001), indicating that NH₄⁺, K⁺, NO₃⁻, BAP, and NAA significantly affected growth. The best callus growth (703%) and the highest production of TPCs (75.17 mg/g) were achieved at an NH₄⁺/K⁺ ratio of 0.33 and BAP/NAA of 0.33, provided that the concentration of plant growth regulators was 30 μM and that of NO₃⁻ was ≤40 mM. According to high-performance liquid chromatography analyses of aerial parts (leaves and stems), in vitro seedlings and callus cultures of R. rosea contain no detectable rosarin, rosavin, rosin, and cinnamyl alcohol. This is the first report on the creation of an experiment for the significant improvement of biomass accumulation and TPC production in callus cultures of R. rosea.

The article talks about the problem of optimization of managerial activities of individual psychologicalcharacteristics. In this connection, line managers, taking into account managerial abilities, authoringmethodological tool of evaluation and selection of line managers who are able to disclose their managerialpotential in socio - professional activity conditions is formulated and tested. This study showed the relationshipbetween the individual abilities and managerial activities of line managers. Analysis of the results of the studyrevealed that managerial abilities and individual psychological characteristics define the "effective" ofmanagerial activities of line managers.

The article presents the key foundations to study contemporary economic innovations. The essence of these innovations is considered, as well as the interdisciplinary approach to their research under the conditions of informational support of the economic activity and the rapid development of the knowledge economy. Author describes the economic innovations phenomenology, where the basic role is played by human capital, integrating the corresponding system of knowledge and capabilities of the economic agent. A humanistic approach is developed to consider intellectual capital, where the need to create a system of economic thinking and the appropriate forms of discourse are highlighted.
