Rhizoeconomics: Carbon costs of phosphorus acquisition (2005, background): “The spatial localization of exudate production near the root apex, prior to the appearance of large microbial populations, may be one means of reducing such competition (Marschner and Römheld, 1996).”
Different roles of rhizosphere effect and long-term fertilization in the activity and community structure of ammonia oxidizers in a calcareous fluvo-aquic soil (2013, background): “It is well known that the microenvironments in the rhizosphere differ markedly from those in bulk soil owing to interactions among root exudations, plant absorption and rhizosphere microorganisms (Neumann and Römheld, 2002; Sørensen, 1997).”
Responses of extracellular enzyme activities and microbial community in both the rhizosphere and bulk soil to long-term fertilization practices in a fluvo-aquic soil (2012, background): “Total PLFA biomass in the rhizosphere significantly increased in comparison with the bulk soil, which can be attributed to root-induced shifts in microbial activity (Neumann and Römheld, 2002).”
Plant-driven selection of microbes (2009, background): “Strategy I involves the stimulation of proton extrusion, enhanced exudation of reductants and chelators (carboxylates and phenolics) and an enhanced activity of plasma-membrane-bound Fe-(III)-reductase (Marschner 1991; Marschner and Römheld 1994; Rengel 1999).”
Influence of enhanced malate dehydrogenase expression by alfalfa on diversity of rhizobacteria and soil nutrient availability (2003, background): “Mobilization of other soil nutrients, such as Fe, Mn, or Zn, has been related to complexation with organic acids contained in root exudates (Dinkekaker et al., 1989; Marschner and Römheld, 2001).”
The dark septate endophytic fungus Phialocephala fortinii is a potential decomposer of soil organic compounds and a promoter of Asparagus officinalis growth (2017, background): “Although P is abundant in agricultural soils, it is mostly in an insoluble form, and it hence cannot be utilized directly by plants (Neumann and Romheld, 2002; Miller et al., 2010; Moe, 2013).”
Roots of the Second Green Revolution (2007, background): “2002), associated with metal mobilisation in the rhizosphere via protons, phenolics and organic acids in dicots and with phytosiderophores in cereals (Neumann and Römheld 2002; Rengel 1999, 2002).”
The role of root exudates and allelochemicals in the rhizosphere (2003, background): “duction and release of root exudates favors the further long-term release of nutrients from the solid phase as nutrients in solution are consumed (Neumann and Romheld, 2002).”
Fertilizer-induced Changes in Rhizosphere Electrical Conductivity: Relation to Forest Tree Seedling Root System Growth and Function (2005, background): “This effect is further confounded by the influence of fertilizer nutrients on ion exchange between root and soil along with root metabolic processes, which may lead to as much as a 2 – 3 unit change in rhizosphere pH compared to bulk soil (Neumann and Romheld 2001).”
Stability and dynamics of enzyme activity patterns in the rice rhizosphere: Effects of plant growth and temperature (2017, background): “The spatial distribution of the rhizosphere is a dynamic function of the soil matrix and plant properties, including root development and morphology, microbial colonization, nutrient uptake, root exudation and rhizodeposition (Dazzo and Gantner, 2012; Neumann and Romheld, 2002).”
Root Development and Nutrient Uptake (2006, background): “The rhizosphere can be defined as the volume of soil influenced by root activity; hence, the physical, chemical and biological characteristics within this zone differ drastically from those of bulk soil (Marschner, 1995; Neumann and Römheld, 2000, 2002).”
