Arabidopsis	At1g08090	Involved in nitrate transport, but does not seem to be able to mediate transport by its own.	Major alterations of the regulation of root NO(3)(-) uptake are associated with the mutation of Nrt2.1 and Nrt2.2 genes in Arabidopsis.; 2001; DOI: 10.1104/pp.127.1.262; PMID: 11553754; https://pubmed.ncbi.nlm.nih.gov/11553754/ | Disruption of the nitrate transporter genes AtNRT2.1 and AtNRT2.2 restricts growth at low external nitrate concentration.; 2004; DOI: 10.1007/s00425-004-1266-x; PMID: 15107992; https://pubmed.ncbi.nlm.nih.gov/15107992/ | The putative high-affinity nitrate transporter NRT2.1 represses lateral root initiation in response to nutritional cues.; 2005; DOI: 10.1073/pnas.0504219102; PMID: 16157886; https://pubmed.ncbi.nlm.nih.gov/16157886/ | A central role for the nitrate transporter NRT2.1 in the integrated morphological and physiological responses of the root system to nitrogen limitation in Arabidopsis.; 2006; DOI: 10.1104/pp.105.075721; PMID: 16415211; https://pubmed.ncbi.nlm.nih.gov/16415211/ | Dissection of the AtNRT2.1:AtNRT2.2 inducible high-affinity nitrate transporter gene cluster.; 2007; DOI: 10.1104/pp.106.091223; PMID: 17085507; https://pubmed.ncbi.nlm.nih.gov/17085507/ | Nitrate signaling and the two component high affinity uptake system in Arabidopsis.; 2007; DOI: 10.4161/psb.2.4.3870; PMID: 19704673; https://pubmed.ncbi.nlm.nih.gov/19704673/
