Signaling pathways involved in the repression of root nitrate uptake by nitrate in Arabidopsis thaliana

V. Chaput, J. Li, D. Sere, P. Tillard, C. Fizames, T. C. Moyano, K. Zuo, A. Martin, R. A. Gutierrez, A. Gojon, L. Lejay

The paper identifies molecular elements and signaling pathways involved in the repression of NRT2 transporters and root nitrate uptake in Arabidopsis in response to nitrate.

A phospho-switch in the N-terminus of NRT2.1 affects nitrate uptake by controlling the interaction of NRT2.1 with NAR2.1

Z. Li, X. N. Wu, A. Jacquot, L. Lejay, W. X. Schulze

The paper identifies a phospho-switch mechanism in NRT2.1 where phosphorylation at S21 and S28 modulates its interaction with NAR2.1 and NURK1, affecting nitrate uptake.
