Three dimensional reconstruction of plant roots via low energy x-ray computed tomography
Plant roots are vital organs for water and nutrient uptake. The structure and spatial distribution of plant roots in the soil affects a plant's physiological functions such as soil-based resource acquisition, yield and its ability to live under abiotic stress. Visualizing and quantifying roots' …

Unearthing the mechanisms of the mycorrhizal-bacterial symbiosis in plant roots using a metatranscriptomic approach
… conserved symbiosis with a majority of land plants which provides plant hosts with increased capability for soil nutrient uptake. These endosymbiotic fungi are themselves colonized by a diverse group of bacteria, including both parasitic and symbiotic species. Recently several obligate …

Do Roots Bind Soil? Comparing the Physical and Biological Role of Plant Roots in Streambank Fluvial Erosion
… quantify the physical and biological effects of roots on streambank fluvial erosion. A series of laboratory-scale erosion tests were conducted using a mini jet erosion testing device and a recirculating flume channel to address this goal. Several soil and vegetation factors that influence fluvial …

The role of living plant roots and cattle manure as a soil amendment in the alleviation of compacted coal mine soils
… mine soils, compaction is of great importance in plant growth and the environment because its high levels may adversely result in the degradation of soil structure, reduced nutrient distribution and reduced root growth, which eventually decreases plant growth. To ensure a productive vegetation, …

Plants Roots Penetration Mechanism on Green Roof Waterproofing Membranes
… of a method which allows clear observation of plant roots during its growth. Preliminary study based on the Forschungsgesellschaft Landschaftsentwicklung Landschaftsbau e.V. (FLL) was carried out. It proved that plant roots will damage waterproofing, although there is little information …

Soil stabilization properties of flexible intruders
In many locations, soil is held in place by the roots of plants. When these plants are removed or die, the soil loses its cohesive strength and erodes away. We seek to create artificial soil stabilizers that use the same physical principles as the plant roots. To investigate how flexible materials …

A methodological investigation into the roots of the resurrection plant, Xerophyta viscosa, for further proteomic analyses
… on the hydrated root tissues of the resurrection plant, Xerophyta viscosa Baker, aeroponically grown plant roots were subjected to various proteomic techniques. Three protein extraction methods were investigated, of which one method, was the most suited in isolating total protein from the root …

The analysis of Metarhizium robertsii potential as endophytic plant root coloniser, plant growth enhancer and antagonist to bean root pathogen Fusarium solani f. sp. phaseolis.
… fungus Metarhizium robertsii also colonizes plant roots endophytically, thus showing potential as a plant symbiont. M robertsii is not randomly distributed in soils but preferentially associates with the plant rhizosphere when applied in agricultural settings. Root surface and endophytic …

A novel non-invasive optical method for quantitative visualization of pH and oxygen dynamics in soils
… scales. Soil structures such as aggregates, roots, layers or macropores enhance the patchiness of these distributions. At the same time it is difficult to access the spatial distribution and temporal dynamics of these parameter. Noninvasive imaging techniques with high spatial and temporal …

Development of Multifunctional Electrical Impedance Spectroscopy System for Characterization in Plant Phenotyping
Plant phenotyping plays an important role for the thorough assessment of plant traits such as growth, development, resistance, physiology, etc. Assessing the nutrients and water contents by obtaining the spectroscopy data is essential for plant characterization, and photosynthesis. The conventional …

The influence of fungi upon soil structure and soil water relations
… increases in fungal biomass and enmeshment by plant roots. Soil in the direct vicinity of plant roots showed the most significant increases in aggregated structures, indicating that plant root enmeshment was one of the predominant factors in soil aggregation. Soil water repellency was directly …

Identification of the Polar Flagellum Genes in Azospirillum brasilense
… a nitrogen fixing rhizobacterium, can colonize plant roots and increase the yield of economically important cereals, such as rice and grasses. This organism has a mixed pattern of flagellation: a single polar flagellum for motility in liquid medium and lateral flagella which might be involved in …

Truffle crops and soil drugs : new fungal practices and epistemologies for the 21st century
… how a beneficial relationship between plant roots and fungi has become meaningful in twenty-first century industrial societies. This fungus-root connection, which exists with over eighty percent of plant species, is called the mycorrhizal symbiosis.

Vanadium uptake and transport in higher plants
… and transport of vanadium in several higher plant species has been examined. Studies utilizing excised Hordeum roots have revealed the uptake patterns of two different ionic species of vanadium (V02+ and V03) to be similar. Both ionic forms exhibited a large extracellular component in their …

Elucidating the Molecular Pathways Involved in the Fitness and Water Stress Response of Pseudomonas synxantha 2-79 in the Plant Rhizosphere
… molecular adaptation of 2-79-like bacteria to plants growing in dry soils is poorly understood. We hypothesized that the ability of 2-79 to colonize and persist in the rhizosphere of water-stressed plants is underpinned by the formation of hydrating biofilms and the utilization of root exudates …
