The Arabidopsis NRT1.1 transporter acts as a nitrate sensor and governs root colonization via modification of local auxin concentration

Archive ouverte | Bouguyon, Eléonore | CCSD

International audience

HIGH NITROGEN INSENSITIVE 9 (HNI9)-mediated systemic repression of root NO3- uptake is associated with changes in histone methylation.

Archive ouverte | Widiez, Thomas | CCSD

International audience. In plants, root nitrate uptake systems are under systemic feedback repression by the N satiety of the whole organism, thus adjusting the N acquisition capacity to the N demand for growth; how...

Nitrate-regulated auxin transport by NRT1.1 defines a mechanism for nutrient sensing in plants.

Archive ouverte | Krouk, Gabriel | CCSD

Travail soutenu par la Fondation Agropolis (projet 07024) et par le CNRS (projet PEPS INSB).. International audience. Nitrate is both a nitrogen source for higher plants and a signal molecule regulating their develo...
