Quorum-sensing-controlled processes are considered to be important for the competitiveness of microorganisms in the rhizosphere. They affect cell-cell communication, biofilm formation, and antibiotic production, and the GacS-GacA two-component system plays a role as a key regulator. In spite of the importance of this system for the regulation of various processes, strains with a Gac(-) phenotyp...

The interaction between plants and microorganisms, which is the driving force behind the decontamination of petroleum hydrocarbon (PHC) contamination in phytoremediation technology, is poorly understood. Here, we aimed at characterizing the variations between plant compartments in the microbiome of two willow cultivars growing in contaminated soils. A field experiment was set-up at a former pet...

Volatile compounds, such as short chain alcohols, acetoin, and 2,3-butanediol, produced by certain strains of root-associated bacteria (rhizobacteria) elicit induced systemic resistance in plants. The effects of bacterial volatile compounds (BVCs) on plant and fungal growth have been extensively studied; however, the impact of bacterial BVCs on bacterial growth remains poorly understood. In thi...

Agricultural practices can affect root-associated microbiota, but the effect of fertilization is still poorly examined. The aim this study was to obtain 16S and ITS metagenomic profiles tomato rhizosphere root endosphere under mineral (NPK) in open field experiment south West Siberia. We found 6 bacterial 3 fungal phyla roots 24 16 rhizosphere. Proteobacteria Actinobacteria together contributed...

Bioaugmentation is commonly employed as a remediation technology. However, numerous studies indicate that introduced microorganisms often do not survive in the environment and thus do not increase contaminant remediation. This review details several new approaches that may increase the persistence and activity of exogenous microorganisms and/or genes following introduction into the environment....

Microorganisms are a substantial component of the rhizosphere, and activity composition rhizosphere microbial populations markedly affect interactions between plants soil environment. In addition, microbiota can positively influence plant development, growth vitality. vineyards, management practices both grapevine root directly microbiota, but exact mode action is largely unknown. Recently, how...

The extensive global use of bisphenols (bisphenol A (BPA) and its analogs) is serious concern to human health aquatic ecosystems. Aquatic plants rhizosphere microorganisms can largely affect the environmental fate bisphenols. In this study, association between common reed, which distributed widely in environment, existing surrounding area roots was studied illustrate capabilities possible mecha...

The process of migration organic carbon from the biochar into substrate and aqueous phase was simulated. in passive washing mode evaluated. Part washed with water passed phase, other part remained mass biochar. Biochar can be a source available carbon, providing nutrition to rhizosphere microorganisms that improve mineral plants, both short long term.
