Journal ArticleDOI
Nitrate transport and signalling
TL;DR: From the range of concentrations present in the soil it is proposed that the HATS functions chiefly as a sensor for root NO(3)(-)-inducible part of HATS, which is important for a second function in sensing NO( 3)(-) availability at the surface of the root.
Journal ArticleDOI
Extracellular Ca2+ Ameliorates NaCl-Induced K+ Loss from Arabidopsis Root and Leaf Cells by Controlling Plasma Membrane K+-Permeable Channels
Sergey Shabala,Vadim Demidchik,Lana Shabala,Tracey Ann Cuin,Susan J. Smith,Anthony J. Miller,Julia M. Davies,Ian Newman +7 more
TL;DR: The results suggest an additional mechanism of Ca2+ action on salt toxicity in plants: the amelioration of K+ loss from the cell by regulating (both directly and indirectly) K+ efflux channels.
Journal ArticleDOI
Arabidopsis root K+-efflux conductance activated by hydroxyl radicals: single-channel properties, genetic basis and involvement in stress-induced cell death
Vadim Demidchik,Tracey Ann Cuin,Dimitri A. Svistunenko,Susan J. Smith,Anthony J. Miller,Sergey Shabala,Anatoliy Sokolik,Vladimir Yurin +7 more
TL;DR: New insight is provided into the regulation of plant cation transport by ROS and possible physiological properties of plant HR-activated K+ channels are demonstrated.
Journal ArticleDOI
Characterization of a Two-Component High-Affinity Nitrate Uptake System in Arabidopsis. Physiology and Protein-Protein Interaction
Mathilde Orsel,Franck Chopin,Olivier Leleu,Susan J. Smith,Anne Krapp,Françoise Daniel-Vedele,Anthony J. Miller +6 more
TL;DR: Results show that AtNAR2.1 is essential for HATS of nitrate in Arabidopsis, and that constitutive root expression of a tobacco gene, NpNRT2.
Journal ArticleDOI
Amino acids and nitrate as signals for the regulation of nitrogen acquisition
TL;DR: In support of this idea, both nitrate and ammonium influx and transporter transcript were shown to decrease in root tissue treated with exogenously applied amino acids, and a possible specific role for cytosolic nitrate is suggested.
