Rhizosphere/Soil Microorganisms in the Phytoremediation of Biphenyl and Dioxane
… and dioxane biodegradation by poplar and willow rhizosphere microorganisms was studied in a phytoremediation test-plot contaminated with biphenyl and dioxane. A dioxane-degrading consortium enriched from the contaminated rhizosphere soil did not use dioxane as the sole source of carbon and …

Plant genotype, immunity and soil composition control the rhizosphere microbiome
… The microbiome community structure of the plant rhizosphere in each generation was characterised using ARISA DNA fingerprinting and 454 sequencing. Rhizosphere bacterial and fungal communities are different from those in bulk soil and there are also differences in the microbial community between …

Defining the Host Genetic Control of the Barley Rhizosphere Microbiota
… plant roots, collectively referred to as the rhizosphere microbiota, to uncouple profitable crop yield from the input of synthetic compounds in the agroecosystem. In the last decade technical advances have allowed scientists to gain unprecedented insights into plant-microbiota interactions in …

Metatranscriptomic analysis of community structure and metabolism of the rhizosphere microbiome.
Plant-microbe interactions in the rhizosphere, the region of soil influenced by plant roots, are integral to biogeochemical cycling, and maintenance of plant health and productivity. Interactions between model plants and microbes are well understood, but relatively little is about the plant …

N2 fixation and rhizosphere ecology of aspalathus linearis subsp. linearis(rooibos tea)
Aspalathus linearis subsp. linearis grows in acid sands of the Cedarberg with pH ranging from 3.8-5.5. Under these conditions:, some essential nutrients are likely to be limiting. In this study, the response of Aspalathus linearis subsp. linearis to N, P, Ca and B was investigated I under field and …

Comparative Analysis of Rhizosphere and Endosphere Microbiome of Different Blueberry Species (Vaccinium sp.)
… with respect to the microbial composition of the rhizosphere and root endosphere. The metagenome analysis showed the presence of various metabolic pathways associated with the interaction. The physiological profiling showed the utilization of different carbon sources by the microbes associated …

Effects of plant flavonoids on the fate of polynuclear aromatic hydrocarbons in rhizosphere soil
… believed that PAH degradation may be enhanced in rhizosphere soil due to the improved aeration condition and the active soil microbial community sustained by root exudates. Whether certain root exudates would influence PAH degradation or bioavailability in soil is not adequately understood. …

Investigating Rhizobium Leguminosarum Metabolism and Rhizosphere Colonization Using High-Throughput Genomics and Erythritol Enrichments
… stress mitigation, sugar transport, and rhizosphere quorum sensing. The results suggest that erythritol may act as a chemical signal that triggers a specialized response in R. leguminosarum 3841 to out-compete other soil bacteria in colonizing the rhizosphere, thereby nodulating legume …

Influence of plant species, location, and seasonality on rhizosphere bacterial communities in freshwater wetlands
… and growth and abiotic stress tolerance. Rhizosphere microbial communities have been shown to vary according to differences in wetland vegetation. Owing to the complexity of factors influencing soil microbial community structure, a greater knowledge of the relationship between rhizosphere …

Understanding Zea mays genetic influence on the structure and function of the rhizosphere microbiome
Assembly of the plant rhizosphere microbiome is driven by plant genetic and evolutionary history. Plant microbiomes play a major role in altering plant resilience, fitness, nutrition, and productivity. Plant hosts selectively filter microorganisms that colonize their rhizosphere. This selective …

Exploring candidate genes and rhizosphere microbiome in relation to iron cycling in Andean potatoes
… in the potato genome). The microorganisms in the rhizosphere react intensely with the various metabolites released by plant roots in a variety of ways such as positive, negative, and neutral. These interactions can influence the uptake and transport of micronutrients in the plant roots. Therefore, …

Investigating Structure and Function of Rhizosphere Associated Microbial Communities in Natural and Managed Plant Systems
… sustainability. Microbial communities in the rhizosphere are known to potentially have beneficial effects on plant growth. Diazotrophs, for example, are bacteria that can convert the atmospheric nitrogen to ammonia, a process called 'nitrogen fixation.' Utilizing the natural process of …

Switchgrass Yield, Nutrient Uptake, And Rhizosphere Microbial Community Composition As Affected By Cultivar And Soil Fertility
… bioenergy crop management decisions may alter rhizosphere microbial populations and associated ecosystem functions such as carbon and N cycling, this research also incorporated next-generation sequencing technology to examine bacterial and fungal community composition as a function of …
