Journal ArticleDOI
Overexpression of AtHMA4 enhances root-to-shoot translocation of zinc and cadmium and plant metal tolerance.
Frédéric Verret,Antoine Gravot,Pascaline Auroy,Nathalie Leonhardt,Pascale David,Laurent Nussaume,Alain Vavasseur,Pierre Richaud +7 more
TL;DR: It is demonstrated that AtHMA4 is localized at the plasma membrane and expressed in tissues surrounding the root vascular vessels and plays a role in metal loading in the xylem.
Journal ArticleDOI
Evidence for a SAL1-PAP Chloroplast Retrograde Pathway That Functions in Drought and High Light Signaling in Arabidopsis
Gonzalo M. Estavillo,Peter A. Crisp,Wannarat Pornsiriwong,Markus Wirtz,Derek Collinge,Chris Carrie,Estelle Giraud,James Whelan,Pascale David,Hélène Javot,Charles A. Brearley,Ruediger Hell,Elena Marin,Barry J. Pogson +13 more
TL;DR: A SAL1-PAP retrograde pathway that can alter nuclear gene expression during HL and drought stress is proposed and it is shown that PAP is a primary in vivo substrate.
Journal ArticleDOI
Low phosphate activates STOP1-ALMT1 to rapidly inhibit root cell elongation.
Coline Balzergue,Thibault Dartevelle,Thibault Dartevelle,Thibault Dartevelle,Christian Godon,Christian Godon,Christian Godon,Edith Laugier,Edith Laugier,Edith Laugier,Claudia-Nicole Meisrimler,Jean-Marie Teulon,Audrey Creff,Marie Bissler,Marie Bissler,Marie Bissler,Corinne Brouchoud,Corinne Brouchoud,Corinne Brouchoud,Agnès Hagège,Jens Daniel Müller,Serge Chiarenza,Serge Chiarenza,Serge Chiarenza,Hélène Javot,Hélène Javot,Hélène Javot,Noëlle Becuwe-Linka,Noëlle Becuwe-Linka,Noëlle Becuwe-Linka,Pascale David,Pascale David,Pascale David,Benjamin Péret,Etienne Delannoy,Marie-Christine Thibaud,Marie-Christine Thibaud,Marie-Christine Thibaud,Jean Armengaud,Steffen Abel,Jean-Luc Pellequer,Jean-Luc Pellequer,Laurent Nussaume,Laurent Nussaume,Laurent Nussaume,Thierry Desnos,Thierry Desnos,Thierry Desnos +47 more
TL;DR: This work genetically uncouple two Pi sensing pathways in the root apex of Arabidopsis thaliana and uncovers STOP1 and ALMT1 as a signalling pathway of low Pi availability and exuded malate as an unexpected apoplastic inhibitor of root cell wall expansion.
Journal ArticleDOI
Transcriptome analysis of Arabidopsis colonized by a plant-growth promoting rhizobacterium reveals a general effect on disease resistance.
Fabienne Cartieaux,Marie-Christine Thibaud,Laurent Zimmerli,Philippe Lessard,Catherine Sarrobert,Pascale David,Alain Gerbaud,Christophe Robaglia,Shauna Somerville,Laurent Nussaume +9 more
TL;DR: RNA transcript levels of Arabidopsis plants, infected by the rhizobacterium Pseudomonas thivervalensis, and axenic control plants were compared and an increase of defence-related transcripts in the shoots of bacterized plants relative to control plants was revealed.
Journal ArticleDOI
Reducing the Genetic Redundancy of Arabidopsis PHOSPHATE TRANSPORTER1 Transporters to Study Phosphate Uptake and Signaling
Amal Ayadi,Pascale David,Jean-François Arrighi,Serge Chiarenza,Marie-Christine Thibaud,Laurent Nussaume,Elena Marin +6 more
TL;DR: Physiological analyses of Arabidopsis lines established that these three genes, along with PHT1;4, are the main contributors to Pi uptake, and revealed that some P HT1 transporters likely exhibit a dual affinity for phosphate, suggesting that their activity is posttranslationally controlled.
