Gene Details:

• Gene ID: Zm00001eb209690
• Gene Symbol: ZmNRT2.2 nrt2.2 nrt1 nrt2-2
• Gene Name: nitrate transport2
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• ZmNRT2.1 and ZmNRT2.2, that have about 98% homology in their amino acid sequence. Both are inducible to NO3− in seedling roots, having been found transcripts of the former in the region of the root cortex while, for the latter, in the cortex, stele, and lateral primordia of the roots.
• NRT2/NRT3 (NAR2)—play an important role in the high-affinity transport of NO3−.
• ZmNRT2.1 and ZmNRT2.2 are inducible to NO3− in seedling roots, having been found transcripts of the former in the region of the root cortex while, for the latter, in the cortex, stele, and lateral primordia of the roots.
• Transcript abundances of putative high-affinity NRTs (predominantly ZmNRT2.1 and ZmNRT2.2) were correlated with two distinct peaks in high-affinity root NO3- uptake capacity and also N availability.
• When N supply was varied (N-inc or N-red), the commonality in change to ZmNRT2.1 and ZmNRT2.2 transcript levels and associated change in NO3- flux capacity further supported this role.
