@article{Jackson2008RootsNT, title={Roots, nitrogen transformations, and ecosystem services.}, author={Louise E. Jackson and Martin Burger and Timothy R. Cavagnaro}, journal={Annual review of plant biology}, year={2008}, volume={59}, pages={ 341-63 } }
This review considers some of the mechanistic processes that involve roots in the soil nitrogen (N) cycle, and their implications for the ecological functions that retain N within ecosystems: 1) root signaling pathways for N transport systems, and feedback inhibition, especially for NO(3)(-) uptake; 2) dependence on the mycorrhizal and Rhizobium/legume symbioses and their tradeoffs for N acquisition; 3) soil factors that influence the supply of NH(4)(+) and NO(3)(-) to roots and soil microbes…

Several mechanisms by which organic N (ON) uptake and assimilation may increase crop NUE are proposed, such as by reducing N assimilation costs, promoting root biomass growth, shaping N cycling microbial communities, recapturing exuded N compounds, and aligning the root uptake capacity to the soil N supply in highly fertilized systems.
Effects of soil nitrogen availability on rhizodeposition in plants: a review

- Environmental Science
- 2006
This review considers how molecular approaches contribute to the exploration of rhizosphere resource exchange, highlighting several recently developed methods linking microbial identity with substrate uptake and gene expression, and parallels linking empirical investigation in the rhzosphere with the quest for understanding general rhizospheric function in Earth’s diverse ecosystems.

Grazing promoted root exudation of carbon, which was quickly assimilated into a burgeoning microbial population in the rhizosphere of clipped plants, which fed back on soil inorganic N pools, plant N uptake, leaf N content, and photosynthesis.

The presented model is based primarily on knowledge about the physiology of a few leguminous crop species and of ecosystem processes in managed, perennial grassland in temperate climatic conditions, and may stimulate thinking about functional relationships between symbiotic N2 fixation and terrestrial ecosystems at various system levels.
MOLECULAR CONTROL POINTS IN RHIZOSPHERE FOOD WEBS

A framework of regulation in the rhizosphere that functions through molecular ''control points'' is suggested, which define control points as regulatory elements that are carried on by selection processes to confer fitness on individual organisms and thereby have effects that propagate through other trophic levels.
