Biological control of bacterial wilt in Arabidopsis thaliana involves abscissic acid signalling

03/20/2012 00:00

Dong Xin Feng, Céline Tasset, Mathieu Hanemian, Xavier Barlet, Jian Hu, Dominique Trémousaygue, Laurent Deslandes and Yves Marco Abstract: Means to control bacterial wilt caused by the phytopathogenic root bacteria Ralstonia solanacearum are limited. Mutants in a large cluster of genes (hrp)...

Genome-Wide Identification, Functional Analysis and Expression Profiling of the Aux/IAA Gene Family in Tomato

02/24/2012 00:00

Corinne Audran-Delalande, Carole Bassa, Isabelle Mila, Farid Regad, Mohamed Zouine and Mondher Bouzayen Abstract: Auxin is a central hormone that exerts pleiotropic effects on plant growth including the development of roots, shoots, flowers and fruit. The perception and signaling of the...

Molecular and biochemical aspects of plant terrestrialization

02/20/2012 00:00

Pierre-Marc Delaux, Amrit Kaur Nanda, Catherine Mathé, Nathalie Sejalon-Delmas and Christophe Dunand Abstract: The transition from water to land was a major evolutionary step for the green lineage. Based on fossil data, this event probably occurred some 480–430 million years ago, during the...

Bacterial effectors target the plant cell nucleus to subvert host transcription

02/01/2012 00:00

Joanne Canonne and Susana Rivas Abstract: In order to promote virulence, Gram-negative bacteria have evolved the ability to inject so-called type III effector proteins into host cells. The plant cell nucleus appears to be a subcellular compartment repeatedly targeted by bacterial effectors....

Identification of the protein sequence of the type III effector XopD from the B100 strain of Xanthomonas campestris pv campestris

02/01/2012 00:00

Joanne Canonne, Carole Pichereaux, Daniel Marino, Dominique Roby, Michel Rossignol and Susana Rivas Abstract: During evolution, pathogens have developed sophisticated strategies to suppress plant defense responses and promote successful colonization of their hosts. In their attempt to quell...

Arabidopsis EDS1 connects pathogen effector recognition to cell compartment-specific immune responses

12/09/2011 00:00

Heidrich K, Wirthmueller L, Tasset C, Pouzet C, Deslandes L, Parker JE Abstract: Pathogen effectors are intercepted by plant intracellular nucleotide binding–leucine-rich repeat (NB-LRR) receptors. However, processes linking receptor activation to downstream defenses remain obscure....

The Arabidopsis thaliana DNA-Binding Protein AHL19 Mediates Verticillium Wilt Resistance

12/01/2011 00:00

Koste A. Yadeta, Mathieu Hanemian, Patrick Smit, Jelle A. Hiemstra, Andy Pereira, Yves Marco and Bart P. H. J. Thomma Abstract: Verticillium spp. are destructive soilborne fungal pathogens that cause vascular wilt diseases in a wide range of plant species. Verticillium wilts are particularly...

Expression and purification of a biologically active Phytophthora parasitica cellulose binding elicitor lectin in Pichia pastoris

12/01/2011 00:00

Mathieu Larroque, Diana Ramirez, Claude Lafitte, Gisèle Borderies, Bernard Dumas and Elodie Gaulin Abstract: The Phytophthora parasitica cellulose-binding elicitor lectin, (CBEL), is a cell wall-localized protein playing a key role in cell wall organization and adhesion of the mycelium to...

Mécanismes de surveillance de l'intégrité pariétale et rôle dans l'induction des réponses de défense chez les plantes

11/29/2011 00:00

Mathieu Larroque Abstract: Les oomycètes sont des organismes filamenteux eucaryotes distincts phylogénétiquement des champignons, dont la plupart sont phytopathogènes. CBEL est une glycoprotéine pariétale de l'oomycète Phythophthora parasitica, pouvant se lier à la cellulose et induire...

Genetic and genomic based approaches towards a better sustainability of sunflower Helianthus annuus resistance to downy mildew Plasmopara halstedi

10/28/2011 00:00

Falah As-Sadi Abstract: Le mildiou du tournesol, causé by P. halstedii, est une des maladies les plus dévastatrice de la culture de tournesol (Helianthus annuus). Les gènes Pl qui confèrent une résistance totale et qualitative, ont été largement utilisés chez les cultivars. Probablement de...
