nitrate transporter 1:2
NCBI Summary
Encodes an inducible component of low-affinity nitrate uptake. mRNA found primarily in root hairs and the epidermis of roots. It also acts as an ABA importer at the site of ABA biosynthesis and is important for the regulation of stomatal aperture in inflorescence stems.

UniProt Comments
Low-affinity proton-dependent nitrate transporter. Involved in constitutive nitrate uptake. Not involved in histidine or dipeptides transport. Involved in (+)-abscisic acid (ABA) transport, but not in gibberellin, indole-3-acetic acid or jasmonic acid import. Mediates cellular ABA uptake. Nitrate does not compete with abscisic acid as a substrate of NPF4.6 (PubMed:24084651).
