Acquisition of phosphorus and nitrogen in the rhizosphere and plant growth promotion by microorganisms (2009, background): “Amino acids in soil solution occur as a result of either direct exudation by roots or from the breakdown of proteins and peptides from soil organic matter and microbial biomass turnover as a result of microbial-derived proteases (Jaeger et al. 1999; Owen and Jones 2001).”
Vascular plant success in a warming Antarctic may be due to efficient nitrogen acquisition (2011, background): “As would be expected from the rapid respiration of peptide and amino acid C following uptake by plant”
Rhizodeposition of organic C by plants: mechanisms and controls (2003, background): “The injection of labeled compounds into the rhizosphere indicated that plant capture was of minor importance compared with microbial uptake of glucose and of charged or uncharged amino acids [129, 131, 153].”
Influence of microbial activity on plant–microbial competition for organic and inorganic nitrogen (2006, background): “In contrast, it is generally thought that plant use of organic N is relatively low in temperate ecosystems due to the high rates of N mineralization and availability of inorganic N in these systems (Bardgett et al. 2003; Owen and Jones 2001; Schimel and Bennett 2004).”
Glucose uptake by maize roots and its transformation in the rhizosphere (2006, methodology): “A similar result has also been reported for amino acids in the rhizosphere (Owen and Jones, 2001; Bardgett et al., 2003).”
Root exudation (net efflux of amino acids) may increase rhizodeposition under elevated CO2 (2006, background): “The characteristics of exudation are strongly affected by the presence of microorganisms (Meharg & Killham, 1995) through their uptake of amino acids outside the root (Owen & Jones, 2001) and by their synthesis of specific molecules that enhance net efflux of amino acids (Phillips et al., 2004).”
Do plant species with different growth strategies vary in their ability to compete with soil microbes for chemical forms of nitrogen (2008, background): “…al., 1999; Owen and Jones, 2001; Bardgett et al., 2003; Jones et al., 2005), largely due to the complete coverage of the soil volume by microbes and their high surface-to-volume ratio which places them in a preferential position to filter amino acids more rapidly than plants (Owen and Jones, 2001).”
Carbon flow in the rhizosphere: carbon trading at the soil–root interface (2009, background): “In agricultural soils, however, it has been shown that plants are poor competitors for amino acids and sugars in comparison to the soil microbial community (Owen and Jones 2001; Bardgett et al. 2003; Kuzyakov and Jones 2006).”
