A major role for the high-affinity nitrate transporter NRT2.1 in increasing root hydraulic conductivity
Title: Dual regulation of root hydraulic conductivity and plasma membrane aquaporins by plant nitrate accumulation and high-affinity nitrate transporter NRT2.1.

Arabidopsis ELONGATED HYPOCOTYL5 (HY5) is a shoot-to-root mobile signal that mediates light promotion of root growth and nitrate uptake. Shoot-derived HY5 auto-activates root HY5 and also promotes root nitrate uptake by activating NRT2.1, a gene encoding a high-affinity nitrate transporter.
Title: Shoot-to-Root Mobile Transcription Factor HY5 Coordinates Plant Carbon and Nitrogen Acquisition.

Glucose elevates NRT2.1 protein levels.
Title: Glucose elevates NITRATE TRANSPORTER2.1 protein levels and nitrate transport activity independently of its HEXOKINASE1-mediated stimulation of NITRATE TRANSPORTER2.1 expression.

Data indicate that leaf nitrogen concentration was lower in mutant nitrate transporter nrt2 than the wild type but was not different for mutant nitrate reductase 2 (nia2) and nitrate reductase 1 (nia1).
Title: Whole-plant and organ-level nitrogen isotope discrimination indicates modification of partitioning of assimilation, fluxes and allocation of nitrogen in knockout lines of Arabidopsis thaliana.

deletion in the high affinity nitrate trasporter NRT2.1 in Arabidopsis results in a reduced susceptibility to Pseudomonas syringae.
Title: A deletion in the nitrate high affinity transporter NRT2.1 alters metabolomic and transcriptomic responses to Pseudomonas syringae.
