“…The object of research was a spring durum wheat cultivar Nikolasha. The seeds before sowing and plants in the tillering phase were inoculated with a suspension of the bacterial strains Azospirillum brasilense Sp245, Sp7, Cd, SR80 and SR88 [17], Ochrobactrum cytisi IPA7.2 [18], as well as Enterobacter cloacae K7 [19], derived from pure bacterial cultures in the logarithmic growth phase. The cell concentration in suspension was 10 8 in 1 ml.…”

The article considers the influence of strains of associative rhizospheric growth-promoting bacteria on the growth and productivity of spring durum wheat. Seeds before sowing and plants in the tillering phase were inoculated with a suspension of rhizospheric bacteria Azospirillum brasilense of strains Sp245, Sp7, Cd, SR80 and SR88, Ochrobactrum cytisi IPA7.2, Enterobacter cloacae K7. Significant differences were observed in terms of productivity of inoculated wheat plants in comparison with the control. Two strains of bacteria A brasilense SR80, SR88 promoted plant growth. Strains of rhizospheric bacteria A. brasilense Sp245, Sp7, SR80, SR88, and E. cloacae K7 under arid conditions of the Volga’s Left Bank of the Saratov Region contributed to an increase in the photo synthetic surface of leaves and the productivity of photosynthesis, which affected the formation of spring durum wheat productivity. Strains of rhizospheric bacteria A brasilense Sp245 and Sp7 positively affected the grain quality. Agrobiotechnology based on associative microsymbionts can be used to optimize environmentally sound technologies for the production of durum wheat (Triticum durum Desf.) in the organic farming system.

“…Similar findings were previously reported by Rodríguez-Romero et al (2008) on micropropagated banana plants with P. fluorescens , with a consistent increase of plant development. Kargapolova et al (2020) have shown the efficacy of the inoculation with Ochrobactrum cytisi on potato microplants. A 50% increase of mitotic index of root meristem cells and 34% increase of shoot length were reported under ex vitro conditions.…”

Plant growth promoting microbes (PGPMs) play major roles in diverse ecosystems, including atmospheric nitrogen fixation, water uptake, solubilization, and transport of minerals from the soil to the plant. Different PGPMs are proposed as biofertilizers, biostimulants, and/or biocontrol agents to improve plant growth and productivity and thereby to contribute to agricultural sustainability and food security. However, little information exists regarding the use of PGPMs in micropropagation such as the in vitro plant tissue culture. This review presents an overview of the importance of PGPMs and their potential application in plant micropropagation. Our analysis, based on published articles, reveals that the process of in vitro classical tissue culture techniques, under strictly aseptic conditions, deserves to be reviewed to allow vitroplants to benefit from the positive effect of PGPMs. Furthermore, exploiting the potential benefits of PGPMs will lead to lessen the cost production of vitroplants during micropropagation process and will make the technique of plant tissue culture more efficient. The last part of the review will indicate where research is needed in the future.

Due to the growing costs of agricultural production and the need to protect the environment, there has been a need to intensify activities leading to an increase in the effectiveness of natural biological processes. These measures should increase the biodiversity of the environment, enable the adaptation of microorganisms and the protection of plants and soils against the background of the concept of sustainable agricultural development. The soil is an important environment in which many elements are transformed, including nitrogen necessary for the proper yielding of plants. The aim of the article is to present the microbiological aspect of nitrogen transformation, starting with a review of historical findings and then to discuss the progress of the latest developments that have contributed to a detailed understanding of the biochemical reactions occurring during nitrogen transformation in soil. Moreover, the aim of the study is to present the current state of knowledge on the dynamics of nitrogen uptake and conversion by various species of microorganisms and the relationship between the activity of nitrogen microorganisms and nitrogen uptake by plants. The article also includes the latest information on the possibility of using microbiological biostimulants supporting plant growth (PGPR) and protection against the effects of phytopathogens.
