[https://www.uniprot.org/uniprot/PTR7_ARATH PTR7_ARATH] Dual affinity nitrate transporter. Involved in proton-dependent nitrate uptake and in the regulation of the nitrate transporter NRT2.1. Acts also as a nitrate sensor that trigger a specific signaling pathway stimulating lateral root growth and seed germination. The uptake activity is not required for sensor function. Displays an auxin transport facilitation inhibited by high nitrate concentration. Required to prevent auxin accumulation in preemerged lateral root primordia and young lateral roots when external nitrate concentration is low or null. May be involved in the basipetal transport of auxin out of the lateral root tips. Acts as a bidirectional transporter involved in root-to-shoot nitrate translocation.<ref>PMID:8453665</ref> <ref>PMID:9844028</ref> <ref>PMID:12606566</ref> <ref>PMID:12509525</ref> <ref>PMID:15319483</ref> <ref>PMID:17148611</ref> <ref>PMID:19766570</ref> <ref>PMID:19633234</ref> <ref>PMID:20627075</ref>
