Post-Translational Regulation of AtFER2 Ferritin in Response to Intracellular Iron Trafficking during Fruit Development in Arabidopsis (2009)

Ravet, Karl, Touraine, Brigitte, Kim, Sun A., Cellier, Françoise, Thomine, Sébastien, Guerinot, Mary Lou, ...

Ferritins are major players in plant iron homeostasis. Surprisingly, their overexpression in transgenic plants led only to a moderate increase in seed iron content, suggesting the existence of...

Distinct pH regulation of slow and rapid anion channels at the plasma membrane of Arabidopsis thaliana hypocotyl cells. (2005)

Colcombet, Jean, Lelièvre, Françoise, Thomine, Sébastien, Barbier-Brygoo, Hélène, Frachisse, Jean-Marie

Variations in both intracellular and extracellular pH are known to be involved in a wealth of physiological responses. Using the patch-clamp technique on Arabidopsis hypocotyl cells, it is shown that...

Arabidopsis thaliana MTP1 is a Zn transporter in the vacuolar membrane which mediates Zn detoxification and drives leaf Zn accumulation. (2005)

Desbrosses-Fonrouge, Anne-Garlonn, Voigt, Katrin, Schröder, Astrid, Arrivault, Stéphanie, Thomine, Sébastien, Krämer, Ute

The Arabidopsis thaliana metal tolerance protein 1 (MTP1) of the cation diffusion facilitator family of membrane transport proteins can mediate the detoxification of Zn in Arabidopsis and yeast....

Cadmium and iron transport by members of a plant metal transporter family in Arabidopsis with homology to Nramp genes

Thomine, Sébastien, Wang, Rongchen, Ward, John M., Crawford, Nigel M., Schroeder, Julian I.

Metal cation homeostasis is essential for plant nutrition and resistance to toxic heavy metals. Many plant metal transporters remain to be identified at the molecular level. In the present study, we...

Sulfate Is Both a Substrate and an Activator of the Voltage-Dependent Anion Channel of Arabidopsis Hypocotyl Cells1

Frachisse, Jean-Marie, Thomine, Sébastien, Colcombet, Jean, Guern, Jean, Barbier-Brygoo, Hélène

On the basis of the anion content of in vitro-cultured Arabidopsis plantlets, we explored the selectivity of the voltage-dependent anion channel of the plasma membrane of hypocotyl cells. In the...

Phylogenetic Relationships within Cation Transporter Families of Arabidopsis1

Mäser, Pascal, Thomine, Sébastien, Schroeder, Julian I., Ward, John M., Hirschi, Kendal, Sze, Heven, ...

Uptake and translocation of cationic nutrients play essential roles in physiological processes including plant growth, nutrition, signal transduction, and development. Approximately 5% of the...

Identification of Features Regulating OST1 Kinase Activity and OST1 Function in Guard Cells1[W]

Belin, Christophe, De Franco, Pierre-Olivier, Bourbousse, Clara, Chaignepain, Stéphane, Schmitter, Jean-Marie, Vavasseur, Alain, ...

The phytohormone abscisic acid (ABA) mediates drought responses in plants and, in particular, triggers stomatal closure. Snf1-related kinase 2 (SnRK2) proteins from several plant species have been...
