Metabolite profiling of pea roots in response to phosphate availability

06/01/2011 00:00

Jérôme Laparre, Coline Balzergue, Soizic Rochange, Pascal Ludwiczak, Fabien Letisse, Jean Charles Portais, Guillaume Bécard and Virginie Puech-Pages Abstract: The arbuscular mycorrhizal (AM) symbiosis is a mutualistic association between soil fungi (Glomeromycota) and roots of most plant...

Photosynthetic growth despite a broken Q-cycle

05/10/2011 00:00

Malnoë A, Wollman FA, de Vitry C, Rappaport F. Abstract: Central in respiration or photosynthesis, the cytochrome bc1 and b6f complexes are regarded as functionally similar quinol oxidoreductases. They both catalyse a redox loop, the Q-cycle, which couples electron and proton transfer. This...

Michael Bessire, Sandra Borel, Guillaume Fabre, Luis Carraça, Nadia Efremova, Alexander Yephremov, Yan Cao, Reinhard Jetter, Anne-Claude Jacquat, Jean-Pierre Métraux and Christiane Nawrath Abstract: Although the multilayered structure of the plant cuticle was discovered many years ago, the...

Nitric oxide production is not required for dihydrosphingosine-induced

05/01/2011 00:00

Daniel Da Silva, Christophe Lachaud, Valérie Cotelle, Christian Brière, Sabine Grat, Christian Mazars and Patrice Thuleau Abstract: Sphinganine or dihydrosphingosine (d18:0, DHS), one of the most abundant free sphingoid Long Chain Base (LCB) in plants, is known to induce a calcium dependent...

L'acétyltransférase PopP2 de Ralstonia solanacearum cible Pip3, un régulateur négatif de la résistance basale chez Arabidopsis thaliana

04/15/2011 00:00

Céline Tasset Abstract: Les bactéries phytopathogènes produisent des facteurs de virulence appelés effecteurs de type III qui sont injectés dans leurs cellules hôtes dans le but de moduler les défenses et fournir à l'agent pathogène un environnement favorable. L'effecteur PopP2 de la...

04/01/2011 00:00

Yann Aubert, Louis-Jérome Leba, Cécilia Cheval, Benoit Ranty, Alain Vavasseur, Didier Aldon and Jean-Philippe Galaud Abstract: The RD20 gene encodes a member of the caleosin family, which is primarily known to function in the mobilization of seed storage lipids during germination. In...

Etude de composés à intérêts technologique et fonctionnel dans la bière

03/28/2011 00:00

Céline Leitao Abstract: L’objectif de ce travail était de développer une boisson maltée originale qui se différencierait des produits existants sur le marché par ses propriétés organoleptiques, notamment par son aspect incolore ou l’ajout de couleurs vives et par la mise en évidence de ses...

Effects of processing steps on the phenolic content and antioxidant activity of beer

01/21/2011 00:00

Leitao C, Marchioni E, Bergaentzlé M, Zhao M, Didierjean L, Taidi B, Ennahar S. Abstract: A new analytical method (liquid chromatography−antioxidant, LC-AOx) was used that is intended to separate beer polyphenols and to determine the potential antioxidant activity of these constituents after...

Phospholipases in action during plant defense signaling

01/13/2011 00:00

Joanne Canonne, Solène Froidure-nicolas and Susana Rivas Abstract: Eukaryotic organisms rely on intricate signaling networks to connect recognition of microbes with the activation of efficient defense reactions. Accumulating evidence indicates that phospholipids are more than mere structural...
