The clock-associated LUX ARRHYTHMO regulates high-affinity nitrate transport in Arabidopsis roots.

ABSTRACT: The circadian clock organizes physiological processes in plants to occur at specific times of the day, optimizing efficient use of resources. Nitrate is a crucial inorganic nitrogen source for agricultural systems to sustain crop productivity. However, because nitrate fertilization has a negative impact on the environment, it is important to carefully manage nitrate levels. Understanding crop biological rhythms can lead to more ecologically friendly agricultural practices. Gating responses through the circadian clock could be a strategy to enhance root nitrate uptake and to limit nitrate runoff. In Arabidopsis, the NITRATE TRANSPORTER 2.1 (NRT2.1) gene encodes a key component of the high-affinity nitrate transporter system. Our study reveals that NRT2.1 exhibits a rhythmic expression patte
