“…For example, IAA from Azospirillum brasilense Sp245 stimulates early plant development and increases significantly the plants and roots yield (in dry weight) and the N-uptake efficiency of wheat [71,80]. The ability to synthesize ABA, particularly under stressful conditions, for example, salinity, and to affect the ABA level in plants was detected in PGPB from the genera Azospirillum, Bacillus, Pseudomonas, Brevibacterium and Lysinibacillus [15,81,82]. Both plants and bacteria can be synthesized via several pathways, including the indole-3-pyruvic acid (IPA), indole-3-acetamide (IAM) and indole-3-acetonitrile (IAN) pathways, which are often regulated by tryptophan, carbon and nitrogen availability, a reduction in growth rate and abiotic factors such as temperature, pH and oxygen [79].…”

Free-living plant growth-promoting rhizobacteria (PGPR) have favourable effect on plant growth, tolerance against stresses and are considered as a promising alternative to inorganic fertilizer for promoting plant growth, yield and quality. PGPR colonize at the plant root, increase germination rates, promote root growth, yield, leaf area, chlorophyll content, nitrogen content, protein content, tolerance to drought, shoot and root weight, and delayed leaf senescence. Several important bacterial characteristics, such as biological nitrogen fixation, solubilization of inorganic phosphate and mineralization of organic phosphate, nutrient uptake, 1-aminocydopropane-1-carboxylic acid (ACC) deaminase activity and production of siderophores and phytohormones, can be assessed as plant growth promotion traits. By efficient use, PGPR is expected to contribute to agronomic efficiency, chiefly by decreasing costs and environmental pollution, by eliminating harmful chemicals. This review discusses various bacteria acting as PGPR, their genetic diversity, screening strategies, working principles, applications for wheat and future aspects in terms of efficiency, mechanisms and the desirable properties. The elucidation of the diverse mechanisms will enable microorganisms developing agriculture further.

“…Reducing the stressful impact of unfavorable temperatures and the lack of excess of soil moisture under bacterization corresponds, in general, to already known data [1-3, 5-6, 13-15] and is attributed to the release of growth-promoting substances by bacteria (hormones, vitamins, etc.) [3,13,17], improvement of mineral nutrition [13], or activation of antioxidant enzyme systems [13,15].…”

“…Application of some microorganisms improving nitrogen and phosphorous nutrition of plants, having a stimulating effect and reducing infestation by phytopathogens, is one of the effective methods to enhance resistance of agricultural plants to stress abiotic factors [1,2,5,[13][14][15][16]. Therefore, a positive effect of plant treatment with different bacterial strains under abiotic stress is demonstrated in several studies.…”

Effect of bacterization with Aeromonas media GS4 and Pseudomonas extremorientalis PhS1 on wheat seedlings under different abiotic conditions * We studied the effect of soft wheat seed treatment (Triticum aestivum L.) with two bacterial strains (Aeromonas media GS4 and Pseudomonas extremorientalis PhS1) isolated from earthworm coprolites on the growth and development of wheat seedlings in a 12-day laboratory experiment, as well as on root rot disease and the activity of guaiacoldependant peroxidase under optimal conditions and abiotic stress (elevated and low temperatures and moisture content). We established that growing nonbacterized wheat plants under stress abiotic conditions reduced the height of plants compared to growing under optimal abiotic conditions, and seed bacterization with P. extremorientalis PhS1 strain increased wheat plant height (by 9-15%) under stress abiotic conditions compared to the nonbacterized plants. Bacterization with both strains decreased infestation of wheat seedlings (2.5-4 times) by root rots under unfavorable abiotic conditions compared to nonbacterized plants. In addition, under optimal and arid conditions, bacterization with P. extremorientalis PhS1 strain was the most effective, and under humid conditions it was bacterization with A. media GS4 strain. We showed that the activity of guaiacoldependant peroxidase correlates with the development of plant resistance to abiotic stress. In our experiments, plant bacterization resulted in a 2-fold increase in peroxidase activity both in leaves and roots of wheat plants compared to the nonbacterized plants. As the result, the ability of bacteria to activate peroxidase can serve as an information indicator of strengthening protective mechanisms of plants during bacterization. The paper contains 4 Figures and 34 References.

The paper highlights the problem of nitrogen fixation in a biological manner and considers prospects for the use of bacterial agents of an associative nature as an element of biotechnology in practice. Studies of promising domestic bacterial agents, based on associative nitrogen fixers, were carried out on zonal soils (chernozems) in the Rostov Region. The presented materials of scientific studies on preparative forms based on nitrogen-fixing microorganisms showed high performance, which was manifested in the progress of crop yields, and therefore these data can be used in agricultural production. Application of bacterial agents with nitrogenfixing species is profitable, since their cost is not high and the increase in additional crop production fully covers the costs and it cuts down the introduction of mineral nitrogen fertilizers. Nevertheless, it should be noted that the environmental aspect of bacterial agents' application consists in obtaining a clean source of nitrogen by cultivated plants and reduces pollution of the soil, atmosphere and water bodies.
