Nitrate transport and signalling.
TLDR
From the range of concentrations present in the soil it is proposed that the HATS functions chiefly as a sensor for root NO(3)(-)-inducible part of HATS, which is important for a second function in sensing NO( 3)(-) availability at the surface of the root. Expand
Analysis of the NRT2 Nitrate Transporter Family in Arabidopsis. Structure and Gene Expression
TLDR
The phylogenetic relationship between NRT2 proteins belonging to several kingdoms is investigated and the structure of the different members of the Arabidopsis family is compared and the significance of each paralog on the basis of the relative levels of gene expression is evaluated. Expand
Characterization of a Two-Component High-Affinity Nitrate Uptake System in Arabidopsis. Physiology and Protein-Protein Interaction1[W]
TLDR
Results show that AtNAR2.1 is essential for HATS of nitrate in Arabidopsis, and that constitutive root expression of a tobacco gene, NpNRT2. Expand
The Arabidopsis Nitrate Transporter NRT2.4 Plays a Double Role in Roots and Shoots of Nitrogen-Starved Plants[C][W]
TLDR
Functional analysis in Xenopus laevis oocytes and in planta showed that NRT2.4 is a nitrate transporter involved both in root nitrate uptake at very low nitrate concentration and in delivering nitrate to the shoot phloem under nitrogen starvation. Expand
Arabidopsis Roots and Shoots Show Distinct Temporal Adaptation Patterns toward Nitrogen Starvation1[W]
TLDR
This multilevel spatiotemporal global study revealed numerous new patterns of adaptation mechanisms to N starvation in adult Arabidopsis plants, which will give new insight for the production of crops with increased N use efficiency. Expand
An Arabidopsis T‐DNA mutant affected in Nrt2 genes is impaired in nitrate uptake
TLDR
It is demonstrated that plant NRT2 proteins do have a role in HATS, and the de‐regulated expression of a Nicotiana plumbaginifolia Nrt2 gene restored the mutant nitrate influx to that of the wild‐type. Expand
Differential regulation of the Chlamydomonas Nar1 gene family by carbon and nitrogen.
TLDR
The expression patterns for Nar1 transcripts showed differential responses to changes in nitrogen or carbon status, as well as a particular regulation by the nitrate assimilation regulatory gene Nit2, which supports the idea that NAR1 proteins may participate in adjusting both nitrite and carbon utilization by Chlamydomonas cells. Expand
Leaf nitrogen remobilisation for plant development and grain filling.
TLDR
The contribution of nitrogen remobilisation efficiency (NRE) to global nitrogen use efficiency ( NUE), and tools dedicated to the determination of NRE are described are described. Expand
Plant homologs of the Plasmodium falciparum chloroquine-resistance transporter, PfCRT, are required for glutathione homeostasis and stress responses
TLDR
It is concluded that a family of three plastid thiol transporters homologous to the Plasmodium falciparum chloroquine-resistance transporter, PfCRT play a significant role in regulating GSH levels and the redox potential of the cytosol. Expand
Nitrate transport in plants: which gene and which control?
TLDR
This is a review of recent progress in the characterization of the NRT2 nitrate transporters, the composition of this family in Arabidopsis, their possible role in nitrate acquisition, and some aspects of their regulation in plants. Expand
