Acquisition of phosphorus and nitrogen in the rhizosphere and plant growth promotion by microorganisms (2009, background): “…composition of exudates varies widely for different species and root types and is primarily comprised of C compounds, exudates can also contain significant quantities of N, which is either available to microorganisms in the rhizosphere or can be recaptured by plants (Bertin et al. 2003; Uren 2007).”
Understanding the roles of nonstructural carbohydrates in forest trees - from what we can measure to what we want to know. (2016, background): “In addition to contributing to soil processes through symbionts, roots exude a wide range of small molecular weight compounds directly into the rhizosphere, including inorganic ions, oxygen and water, enzymes, and a diverse array of C-rich primary and secondary metabolites (Uren, 2007).”
Alleviation of salinity stress in plants by endophytic plant-fungal symbiosis: Current knowledge, perspectives and future directions (2020, background): “Although the concentration of inorganic compounds make up far less of the root exudate composition compared to organic compounds but their role is still significant (Khorassani 2008; Uren 2000).”
Use of plant growth-promoting rhizobacteria to control stress responses of plant roots (2010, background): “The exuded molecules by plant roots are called rhizodeposits, and include carbohydrates, amino acids, fatty acids, nucleotides, organic acids, phenolics, plant growth regulators, putrescine, sterols, and vitamins (Uren 2007).”
Rhizosphere interactions: root exudates, microbes, and microbial communities1 (2014, background): “The qualitative and quantitative composition of root exudates is determined by cultivar, plant species, plant developmental stage, and various environmental factors, including soil type, pH, temperature, and the presence of microorganisms (Badri and Vivanco 2009; Uren 2000).”
CONSEJO SUPERIOR DE INVESTIGACIONES CIENTÍFICAS (2009, background): “El 3060% del carbono fijado en la fotosíntesis puede ser transportado a la raíz, y entre el 40-90% de éste se pierde en forma de exudados radiculares (ERs) o debido a la respiración radicular (Lynch y Whipps, 1990; Uren, 2007).”
The Effect of Tillage System and Crop Rotation on Soil Microbial Diversity and Composition in a Subtropical Acrisol (2012, background): “Besides crops and C:N ratio, root exudates are also key factors that influence microbial communities, as they provide a carbon source to soil microorganisms [22,23].”
Are you what you eat? Physiological constraints on organismal stoichiometry in an elementally imbalanced world (2005, unknown): “Plant roots exude C-rich compounds, including organic acids and phosphatases (to increase P availability), sugars (to increase microbial activity), and ligands (to chelate metals) near the root zone (Uren 2000, Bertin et al. 2003).”
