Abstract

Summary Root NO 3 – uptake and expression of two root NO 3 – transporter genes ( Nrt2;1 and Nrt1 ) were investigated in response to changes in the N‐ or C‐status of hydroponically grown Arabidopsis thaliana plants. Expression of Nrt2;1 is up‐regulated by NO 3 – starvation in wild‐type plants and by ...
