Dual pathways for regulation of root branching by nitrate.
TLDR
A model in which root branching is modulated by opposing signals from the plant's internal N status and the external supply of NO3-. Expand
An Arabidopsis MADS box gene that controls nutrient-induced changes in root architecture.
TLDR
Transgenic plants in which ANR1 was repressed had an altered sensitivity to NO3- and no longer responded to No3--rich zones by lateral root proliferation, indicating that ANR 1 is a key determinant of developmental plasticity in Arabidopsis roots. Expand

  • 1 May 2000
TLDR
Recent progress in the characterisation of the two families of NO(-3) transporters that have so far been identified in plants are reviewed, their structure and their regulation are considered, and the evidence for their roles in NO (-3) acquisition is considered. Expand
Glutamate in plants: metabolism, regulation, and signalling.

  • 1 July 2007
TLDR
Glutamate signalling is examined from an evolutionary perspective, and the roles it might play in plants, both in endogenous signalling pathways and in determining the capacity of the root to respond to sources of organic N in the soil, are considered. Expand
The Arabidopsis NRT1.1 transporter participates in the signaling pathway triggering root colonization of nitrate-rich patches
TLDR
It is concluded that NRT1.1, which is localized at the forefront of soil exploration by the roots, is a key component of the NO3−-sensing system that enables the plant to detect and exploit NO3-rich soil patches. Expand
Local and long-range signaling pathways regulating plant responses to nitrate.

  • Annual review of plant biology
  • 1 June 2002
TLDR
This review examines signaling mechanisms and their interactions with sugar-sensing and hormonal response pathways used by plants as a signal to reprogram plant metabolism and to trigger changes in plant architecture. Expand
The nutritional control of root development
TLDR
The term `trophomorphogenesis' is proposed to describe the changes in plant morphology that arise from variations in the availability or distribution of nutrients in the environment. Expand
Evidence that L-glutamate can act as an exogenous signal to modulate root growth and branching in Arabidopsis thaliana.
TLDR
It is reported here that, at micromolar concentrations and in a genotype-dependent manner, exogenous l-glutamate is also able to elicit complex changes in Arabidopsis root development, with a remarkable degree of natural variation in l-Glutamate sensitivity. Expand
Nitrate and ammonium nutrition of plants: physiological and molecular perspectives
TLDR
The current picture of the mechanisms responsible for the uptake and efflux of nitrate and ammonium is reviewed, attempting to integrate the large body of physiological data with the recent advances in the molecular biology of nitrates and ammonia transporters in bacteria and algae as well as in higher plants. Expand
Gene expression, cellular localisation and function of glutamine synthetase isozymes in wheat (Triticum aestivum L.)
TLDR
expression of GS genes in leaves was developmentally regulated, with both GS2 and GS1 assimilating or recycling ammonia in leaves during the period of grain development and filling, suggesting major roles in assimilating ammonia during the critical phases of remobilisation of nitrogen to the grain.
