Availability of Mn, Zn and Fe in the rhizosphere (2015, background): “This may result from an inherently low nutrient status of soil, low mobility of nutrients within soil, poor solubility of the given chemical form of the nutrient, or the soil-microbe-plant interactions (eg. Rengel, 2002a; Marschner et al., 2011).”
Taxonomical and functional microbial community selection in soybean rhizosphere (2014, background): “Iron is poorly available in most soils and, in the rhizosphere, Fe is mobilized by plant- or microbe-derived compounds, and there is an intense competition for Fe uptake (Marschner et al., 2011).”
Microbial interactions in the rhizosphere: beneficial influences of plant growth-promoting rhizobacteria on nutrient acquisition process. A review (2015, background): “Considering that the higher microbial growth rate (and hence the higher rate of C source consumption) is estimated to be in correspondence of the root distal elongation zone (Marschner et al. 2011), the very localized release of exudates (root tip) can prevent microbial degradation, enhancing their ”
Distribution of microbial- and root-derived phosphatase activities in the rhizosphere depending on P availability and C allocation – Coupling soil zymography with 14C imaging (2013, background): “While plants mostly take up P at the root tip and in the proximal elongation zone, microbial P uptake is highest in the root hair zone, i.e. in the zone of maximal rhizodeposition (Marschner et al., 2011).”
Current overview on the study of bacteria in the rhizosphere by modern molecular techniques: a mini‒review (2015, background): “The limitations of real‒time PCR are related to primer specificity, amplification efficiency, and the concentration of RNA in rhizosphere sample, which may be too low for accurate detection (Marschner et al., 2011).”
Ecophysiology of iron homeostasis in plants (2016, background): “Thus, several compounds secreted by roots form stable Fe chelates such as malic acid, citric acid, phenolic acid and piscidic acid (Guerinot and Yi 1994; Marschner et al. 2011).”
Culture-independent molecular tools for soil and rhizosphere microbiology (2013, methodology): “These methods range from DNA-based techniques [32,33], microscopic observation of labeled microorganisms colonizing roots [34,35], and incorporation of labeled nutrient substrates [36–38].”
Acquisition of phosphorus and other poorly mobile nutrients by roots. Where do plant nutrition models fail? (2011, background): “Besides the release of exudates by plant roots, rhizosphere microorganisms may contribute to the mobilization of poorly available nutrients via the release of microbial metabolites, which is largely documented for P and Fe (Marschner et al. 2011).”
Enzymes of importance to rhizosphere processes (2015, background): “releasing various amounts and different compositions of exudates (Marschner et al., 2011).”
Plant nitrogen uptake drives rhizosphere bacterial community assembly during plant growth (2015, background): “…Padilla et al., 2013) increasing organic carbon availability : þ1 970 491 1965. l). through root exudation (Nannipieri et al., 2008; Kuzyakov, 2010; Bird et al., 2011) and decreasing water and nutrient availability through uptake (Jackson et al., 1989; Herman et al., 2006; Marschner et al., 2011).”
Root Exudation: The Ecological Driver of Hydrocarbon Rhizoremediation (2016, background): “The greatest concentration of exudates occurs mostly at the root tips and at sites of lateral branching, decreasing with increasing distance from the root surface [54,67,144,150].”
The rhizosphere microbiome: significance of plant beneficial, plant pathogenic, and human pathogenic microorganisms. (2013, background): “For more detailed overviews of the mechanisms by which rhizosphere microorganisms influence iron uptake by plants, we refer to Lemanceau et al. (2009a, b), and Marschner et al. (2011).”
Distribution of phosphatase activity and various bacterial phyla in the rhizosphere of Hordeum vulgare L. depending on P availability (2015, background): “…a spatial separation between plant and microbial organic P mineralization in the rhizosphere of Lupinus albus has been shown (Spohn and Kuzyakov, 2013a), which seems to support the concept by Marschner et al. (2011) of a spatial differentiation of organic P mineralization in the rhizosphere.”
