Differential regulation of the NO3 and NH4+ transporter genes AtNrt2.1 and AtAmt1.1 in Arabidopsis: relation with long‐distance and local controls by N status of the plant

Abstract
Regulation of root N uptake by whole‐plant signalling of N status was investigated at the molecular level in Arabidopsis thaliana plants through expression analysis of AtNrt2.1 and AtAmt1.1. These tw...
