"Nitrate-NO" respiration study in symbiotic interaction between Medicago truncatula and Sinorhizobium meliloti : searching for mitochondrial nitrite transporter

12/17/2012 00:00

Marianne Prevot Abstract: Symbiosis between legume plants and nitrogen-fixing bacteria (rhizobium) constitute a major issue to reduce nitrogen fertilization in crops. Central function of nodules is the enzymatic reduction of atmospheric nitrogen (N2) into ammoniac (NH4+) by the bacterial...

Cell autonomous and non-cell autonomous control of rhizobial and mycorrhizal infection in Medicago truncatula

12/06/2012 00:00

Pauline Rival, Jean-Jacques Bono, Clare Gough, Sandra Bensmihen and Charles Rosenberg Abstract: Legumes can form a nitrogen fixing symbiosis with soil bacteria called rhizobia (the RL symbiosis). They can also, like most plants, form symbiotic associations with arbuscular mycorrhizal (AM)...

Régulation de la symbiose endomycorhizienne par le phosphate

12/03/2012 00:00

Coline Balzergue Abstract: La majorité des plantes terrestres forme une symbiose racinaire avec des champignons mycorhiziens à arbuscules. Une forte fertilisation phosphatée est capable d'inhiber très fortement la mycorhization avant même l'attachement du champignon à l'épiderme racinaire....

Arabidopsis wat1 (walls are thin1)-mediated resistance to the bacterial vascular pathogen, Ralstonia solanacearum, is accompanied by cross-regulation of salicylic acid and tryptophan metabolism

Nicolas Denancé, Philippe Ranocha, Nicolas Oria, Xavier Barlet, Marie-Pierre Rivière, Koste A Yadeta, Laurent Hoffmann, François Perreau, Gilles Clément, Alessandra Maia-Grondard, Grardy den Berg, Bruno Savelli, Sylvie Fournier, Yann Aubert, Sandra Pelletier, Bart PHJ Thomma, Antonio Molina, Lise...

The unique architecture and function of cellulose-interacting proteins in oomycetes revealed by genomic and structural analyses

11/09/2012 00:00

Mathieu Larroque, Roland Barriot, Arnaud Bottin, Annick Barre, Pierre Rougé, Bernard Dumas and Elodie Gaulin Abstract: Oomycetes are fungal-like microorganisms evolutionary distinct from true fungi, belonging to the Stramenopile lineage and comprising major plant pathogens. Both oomycetes...

Study of the biosynthesis pathway of the geosmin in Penicillium expansum

11/05/2012 00:00

Muhammad Hussnain Siddique Abstract (in French): La géosmine est un terpénoïde, provoquant un goût moisi-terreux associée à des flaveurs atypiques dans l’eau et le vin. Chez les bactéries, la voie de biosynthèse de la géosmine est bien caractérisée, mais peu de connaissance sont disponibles...

Automating gene library synthesis by structure-based combinatorial protein engineering: examples from plant sesquiterpene synthases

11/03/2012 00:00

Dokarry M, Laurendon C and O'Maille PE Abstract: Structure-based combinatorial protein engineering (SCOPE) is a homology-independent recombination method to create multiple crossover gene libraries by assembling defined combinations of structural elements ranging from single mutations to...

Deciphering the route of Ralstonia solanacearum colonization in Arabidopsis thaliana roots during a compatible interaction: focus at the plant cell wall

11/01/2012 00:00

Catherine Digonnet, Yves Martinez, Nicolas Denancé, Marine Chasseray, Patrick Dabos, Philippe Ranocha, Yves Marco, Alain Jauneau, Deborah Goffner Abstract: The compatible interaction between the model plant, Arabidopsis thaliana, and the GMI1000 strain of the phytopathogenic bacterium,...

Eleven microsatellite markers for the mountain clover Trifolium montanum (Fabaceae)

10/29/2012 00:00

Matter P, Määttänen K, Kettle CJ, Ghazoul J, Pluess AR Abstract: Microsatellite markers were developed in Trifolium montanum to investigate pollen dispersal patterns at landscape scale with a pollen-pool analysis (indirect parentage analysis) as well as in an experimental set-up with a...

Medicago truncatula ERN Transcription Factors: Regulatory Interplay with NSP1/NSP2 GRAS Factors and Expression Dynamics throughout Rhizobial Infection

10/17/2012 00:00

Marion R. Cerri, Lisa Frances, Tom Laloum, Marie-Christine Auriac, Andreas Niebel, Giles E.D. Oldroyd, David G. Barker, Joëlle Fournier and Fernanda de Carvalho-Niebel Abstract: Rhizobial nodulation factors (NFs) activate a specific signaling pathway in Medicago truncatula root hairs that...
