The influence of stonewool substrate on the exudation major soluble carbon nutrients and auxin precursor tryptophane for Pseudomonas biocontrol agents was studied. To this end, composition organic acids sugars, as well that tryptophane, axenically collected exudates seed, seedlings, roots tomato, cucumber, sweet pepper determined. results were follows. i) total amount acid is much higher than sugar. ii) Exudation both sugars increases during plant growth. iii) Citric, succinic, malic...
Drought tolerant rhizobacteria of the genus Bacillus, Enterobacter, Moraxella and Pseudomonas colonizing root system Acacia arabica were isolated to mitigate drought stress wheat (Triticum aestivum L.). In vitro auxin production by was quantified Ultra High Performance Liquid Chromatography (UPLC). Analysis crude extracts detected indole-3-acetic acid (IAA), indole-3-carboxylic (ICA) indole-3-lactic (ILA). Highest IAA 25.9 µg ml−1 observed for Bacillus amyloliquefaciens S-134. Pot trials...
Abstract Plant‐growth‐promoting rhizobacteria ( PGPR ) utilise amino acids exuded from plant root systems, but hitherto there have been no direct measurements of rhizosphere concentrations the acid 1‐amino‐cyclopropane‐1‐carboxylic ACC following inoculation with containing enzyme deaminase. When introduced to two potato Solanum tuberosum cultivars (cv. Swift and cv. Nevsky), various deaminase Achromobacter xylosoxidans Cm4, Pseudomonas oryzihabitans Ep4 Variovorax paradoxus 5C ‐2) not only...
The effects of the pathogenic fungus Fusarium oxysporum f. sp. radicis-lycopersici and bacterial biocontrol strain Pseudomonas fluorescens WCS365, both microbes, on amounts composition root exudate components tomato plants grown in a gnotobiotic stonewool substrate system were studied. Conditions selected under which introduction F. caused severe foot rot, whereas inoculation seed with P. WCS365 decreased percentage diseased from 96 to 7%. This is much better disease control level than was...
Resolving the physiological mechanisms by which rhizobacteria enhance plant growth is difficult, since many such bacteria contain multiple growth-promoting properties. To understand further how 1-aminocyclopropane-1-carboxylate (ACC) deaminase (ACCd)-containing rhizobacterium Variovorax paradoxus 5C-2 affects growth, flows and partitioning of mineral nutrients abscisic acid (ABA) ABA metabolism were studied in pea (Pisum sativum) plants following rhizosphere bacterial inoculation. Although...

Cadmium (Cd) is one of the most widespread and toxic soil pollutants that inhibits plant growth microbial activity. Polluted soils can be remediated using plants either accumulate metals (phytoextraction) or convert them to biologically inaccessible forms (phytostabilization). The phytoremediation potential a symbiotic system comprising Cd-tolerant pea (Pisum sativum L.) mutant SGECdt selected microorganisms, such as growth-promoting rhizobacterium Variovorax paradoxus 5C-2, nodule bacterium...
Gram-stain-negative strains V5/3MT, V5/5K, V5/5M and V5/13 were isolated from root nodules of Vicia alpestris plants growing in the North Ossetia region (Caucasus). Sequencing partial 16S rRNA gene (rrs) four housekeeping genes (dnaK, gyrB, recA rpoB) showed that isolates V. most closely related to species Microvirga zambiensis (order Rhizobiales , family Methylobacteriaceae ) which was described for single isolate nodule Listia angolensis Zambia. Sequence similarities between -related M....
The phytohormone abscisic acid (ABA) plays an important role in plant growth and response to abiotic stress factors. At the same time, its accumulation soil can negatively affect seed germination, inhibit root increase sensitivity pathogens. ABA is inert compound resistant spontaneous hydrolysis biological transformation scarcely understood. Recently, strain Rhodococcus sp. P1Y was described as a rhizosphere bacterium assimilating sole carbon source batch culture affecting concentrations...
Streptomycetes produce a huge variety of bioactive metabolites, including antibiotics, enzyme inhibitors, pesticides and herbicides, which offer promise for applications in agriculture as plant protection growth-promoting products. The aim this report was to characterize the biological activities strain Streptomyces sp. P-56, previously isolated from soil an insecticidal bacterium. metabolic complex obtained liquid culture P-56 dried ethanol extract (DEE) possessed activity against vetch...
Aluminium being one of the most abundant elements is very toxic for plants causing inhibition nutrient uptake and productivity. The aim this study was to evaluate potential microbial consortium consisting arbuscular mycorrhizal fungus (AMF), rhizobia PGPR counteracting negative effects Al toxicity on four pea genotypes differing in tolerance. Pea were grown acid soil supplemented with AlCl3 (pHKCl = 4.5) or neutralized CaCO3 6.2). Inoculation increased shoot and/or seed biomass...
The present work was designed to study the role of phytohormones, cytokinin and auxin, in symbiosis development between pea Pisum sativum L. Rhizobium leguminosarum bv. viciae. To achieve this aim, temporal expression patterns genes related auxin biosynthesis, perception, response were studied. It found that most these showed specific transcriptional regulations upon nodulation at various stages following inoculation. Once they purified using chromatographic methods, endogenous cytokinins...
