Constitutive expression of a putative high‐affinity nitrate transporter in Nicotiana plumbaginifolia: evidence for post‐transcriptional regulation by a reduced nitrogen source

Abstract
The NpNRT2.1 gene encodes a putative inducible component of the high‐affinity nitrate (NO3–) uptake system in Nicotiana plumbaginifolia. Here we report functional and physiological analyses of transg...
