Low-affinity nitrate transporter involved in xylem-to-phloem transfer for redistributing nitrate into developing leaves. Not involved in dipeptides transport. Expressed in shoots, stems, leaves, flowers and siliques. Mainly detected in larger expanded leaves, in the companion cells of major veins. Nrt1.11 and nrt1.12 double mutant is defective in high-nitrate-enhanced growth. Belongs to the major facilitator superfamily. Proton-dependent oligopeptide transporter (POT/PTR) (TC 2.A.17) family. Truncated N-terminus.
