Enhanced NRT1.1/NPF6.3 expression in shoots improves growth under nitrogen deficiency stress in Arabidopsis

Abstract

Here, the authors conduct a genome-wide association study from Arabidopsis thaliana accessions and demonstrate that the polymorphisms in the promoter of NRT1.1/NPF6.3, a dual-affinity nitrate transporter, are associated with different magnitudes of N deficiency in Arabidopsis shoot.
