Nitrogen uptake, assimilation and remobilization in plants: challenges for sustainable and productive agriculture.
TLDR
This review presents the complexity of NUE and supports the idea that the integration of the numerous data coming from transcriptome studies, functional genomics, quantitative genetics, ecophysiology and soil science into explanatory models of whole-plant behaviour will be promising. Expand
Bay-0 × Shahdara recombinant inbred line population: a powerful tool for the genetic dissection of complex traits in Arabidopsis
TLDR
The accuracy of QTL detection is confirmed using the Bay-0 × Shahdara RIL population, which constitutes the largest in size available so far in Arabidopsis, which represents a powerful tool which is currently being used to undertake the genetic dissection of complex metabolic pathways. 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
The nodule inception-like protein 7 modulates nitrate sensing and metabolism in Arabidopsis.
TLDR
It is reported that Arabidopsis thaliana NIN-like protein 7 (NLP7) knockout mutants constitutively show several features of nitrogen-starved plants, and that they are tolerant to drought stress. 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 putative high-affinity nitrate transporter NRT2.1 represses lateral root initiation in response to nutritional cues.
TLDR
It is proposed that Arabidopsis NRT2.1 acts either as a nitrate sensor or signal transducer to coordinate the development of the root system with nutritional cues and that this role is independent of nitrate uptake. Expand
Molecular and functional regulation of two NO3- uptake systems by N- and C-status of Arabidopsis plants.
TLDR
Observations show that expression of Nrt2;1 is under feedback repression by N-metabolites resulting from NO3- reduction, and changes in the Nrt1 mRNA level are not always associated with similarChanges in the activities of high- or low-affinity No3- transport systems. Expand
Nitrate transport and signalling in Arabidopsis.
TLDR
A global picture of the nitrate transporters so far identified and the recent advances in the molecular knowledge of the so-called primary nitrate response, the rapid regulation of gene expression in response to nitrate are focused on. 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
