Arabidopsis	At1g52190	Low-affinity nitrate transporter involved in xylem-to-phloem transfer for redistributing nitrate into developing leaves.	Two phloem nitrate transporters, NRT1.11 and NRT1.12, are important for redistributing xylem-borne nitrate to enhance plant growth.; 2013; DOI: 10.1104/pp.113.226563; PMID: 24006285; https://pubmed.ncbi.nlm.nih.gov/24006285/
