Official Symbol: NRT1.1
Official Full Name: nitrate transporter 1.1
Primary source: TAIR:AT1G12110
Locus tag: AT1G12110
See related: Araport:AT1G12110
Gene type: protein coding
RefSeq status: REVIEWED
Organism: Arabidopsis thaliana (ecotype: Columbia)
Lineage: Eukaryota; Viridiplantae; Streptophyta; Embryophyta; Tracheophyta; Spermatophyta; Magnoliopsida; eudicotyledons; Gunneridae; Pentapetalae; rosids; malvids; Brassicales; Brassicaceae; Camelineae; Arabidopsis
Also known as: ARABIDOPSIS THALIANA NITRATE TRANSPORTER 1; AtNPF6.3; ATNRT1; ATNRT1.1; B-1; CHL1; CHL1-1; CHLORATE/NITRATE TRANSPORTER; CHLORINA 1; F12F1.1; F12F1_1; NITRATE TRANSPORTER 1; nitrate transporter 1.1; NITRATE/CHLORATE TRANSPORTER; NPF6.3; NRT1; NRT1/ PTR family 6.3
Summary: Encodes NRT1.1 (CHL1), a dual-affinity nitrate transporter. The protein is expressed in guard cells and function in stomatal opening. Mutants have less transpiration and are more tolerant to drought. Expressed in lateral roots. Involved in nitrate signaling which enables the plant root system to detect and exploit nitrate-rich soil patches. Comparing to the wild type, the mutant displays a strongly decreased lateral root proliferation phenotype in nitrate rich patches on growth medium.
