This report is part of a serial study applying stable isotope labelling to rice microcosms to track the utilization of recently photosynthesized carbon by active microbiota in the rhizosphere. The objective of the present study was to apply phospholipid fatty acid-based stable isotope probing (PLFA-SIP) to detect the spatial variation of active microorganisms associated with rhizosphere carbon ...

All processes and functions taking place in the rhizosphere are dominated by the activities of plant roots, rhizosphere microorganisms and root-microorganism interactions, and enzymes are recognized as main actors of all activities occurring in rhizosphere environments. Rhizosphere enzymes have, in general, a higher activity than those operating in bulk soil, as the rhizosphere soil is richer i...

The rhizosphere represents the thin layer of soil surrounding plant roots and the soil occupied by the roots, supports large active groups of microorganisms. The vast organic compounds (amino acids, sugars etc.) secreted by plant roots in the rhizosphere provide a food source for microorganisms increasing microbial biomass and their activity in the rhizosphere. Antibiotics are antimicrobial com...

All the microorganisms produce primary and secondary metabolites which have various industrial applications. Metabolites such as antibiotics are mainly produced by the filamentous microorganisms such as bacteria and fungi. The rhizosphere is a narrow zone surrounding and influenced by plant roots and also a hot spot for several organisms. Organisms found in vicinity of roots include bacteria, f...

Millions of microbial taxa inhabit the rhizosphere and could be used as biofertilizers, biopesticides, and/or for bioremediation. Only a fraction of these microbes have been described and/or are being utilized. Most are dispersed in collections, but coordination of their accessibility and availability is challenging. Here, we present the Pan-European Rhizosphere Resource Network (PERN), which i...

Modulation of the effect of wheat germ agglutinin (WGA) with hapten, N-acetyl-D-glucosamine (GlcNAc), in case of pre-sowing treatment of spring wheat (Triticum aestivum cv Rannyaya 93) seeds, on the biological components of the system ’’plant – soil – microorganisms” was studied. The application of WGA (100 nM) stimulated root formation, biomass production, total chlorophyll content and wheat g...

ing in the rhizosphere for decades, in the form of plant growth-promoting microorganisms. Efforts to incorporate microbial management into mainstream practices have not been successful. In fact, the same practices that increased yields in the last 50 years (namely fertilizers, herbicides, and pesticides) have largely eradicated natural rhizosphere microbes in agrosystems (Matson et al. 1997) an...

The rhizosphere was defined over 100 years ago as the zone around the root where microorganisms and processes important for plant growth and health are located. Recent studies show that the diversity of microorganisms associated with the root system is enormous. This rhizosphere microbiome extends the functional repertoire of the plant beyond imagination. The rhizosphere microbiome of Arabidops...

Rhizosphere, the interface between soil and plant roots, is a chemically complex environment which supports the development and growth of diverse microbial communities. The composition of the rhizosphere microbiome is dynamic and controlled by multiple biotic and abiotic factors that include environmental parameters, physiochemical properties of the soil, biological activities of the plants and...

Background: In consideration for the increasing widespread use of genetically modified (GM) crops, one of the important issues for assessment is the effect of GM crops on soil microbial communities Objectives: In this study, T2 chitinase-transgenic cotton (line #57) and its non-transgenic line were investigated for bacterial and fungal dynamics...
