Gene Details:

• Gene ID: Zm00001eb416090
• Gene Symbol: ZmNRT1.1A ZmNPF6.4 npf1
• Gene Name: nitrate transporter/peptide transporter family1
• Genome: Zm-B73-REFERENCE-NAM-5.0
• Species: Zea mays

Functional Descriptions:

• NO3− transport is necessary for NO3−-promoted Al resistance, with ZmNRT1.1A and AtNRT1.1 potentially playing vital roles.
• Despite this, correlation analysis based on 10 different maize inbred and hybrid lines regarding NO3–-enhanced Al resistance revealed that only the NO3–-promoted expression of ZmNRT1.1A in root tips was positively correlated with the NO3–-promoted relative root-elongation under Al stress.
• NO3- transport guided by ZmNRT1.1A can conservatively enhance tolerance to aluminum stress.
• ZmNRT1.1A is a homologue of AtNPF6.3,AtNPF6.3 (AtNRT1.1) has been shown to be one of the main contributors to both high and low-affinity nitrate uptake.
• ZmNRT1.1A and AtNRT1.1 are important for the alleviation of Al-induced inhibition of root elongation by nitrate in maize and Arabidopsis.
• ZmNRT1.1A encodes a low-affinity nitrate transporter with efflux activity; switches to a high-affinity chloride selective transporter, when supplied chloride.
