Visualization of grapevine root colonization by the Saharan soil isolate Saccharothrix algeriensis NRRL B-24137 using DOPE-FISH microscopy

09/01/2013 00:00

Stéphane Compant, Saima Muzammil, Ahmed Lebrihi and Florence Mathieu Abstract: There is currently a gap of knowledge regarding whether some beneficial bacteria isolated from desert soils can colonize epi- and endophytically plants of temperate regions. In this study, the early steps of the...

A one-pot enzymatic approach to the O-fluoroglucoside of N-methylanthranilate

08/15/2013 00:00

Lorenzo Caputi, Martin Rejzek, Thomas Louveau, Ellis C. O’Neill, Lionel Hill, Anne Osbourn and Robert A. Field Abstract: In connection with prospective 18F-PET imaging studies, the potential for enzymatic synthesis of fluorine-labelled glycosides of small molecules was investigated....

Control of NO level in rhizobium-legume root nodules: Not only a plant globin story

08/14/2013 00:00

Eliane Meilhoc, Pauline Blanquet, Yvan Cam and Claude Bruand Abstract: Nitric oxide (NO) is a gaseous signaling molecule which plays both regulatory and defense roles in animals and plants. In the symbiosis between legumes and rhizobia, NO has been shown to be involved in bacterial infection...

Use of beneficial bacteria and their secondary metabolites to control grapevine pathogen diseases

08/01/2013 00:00

Stéphane Compant, Günter Brader, Saima Muzammil, Angela Sessitsch, Ahmed Lebrihi, Florence Mathieu Abstract: Grapevine is one of the most important economic crops yielding berries, wine products as well as derivates. However, due to the large array of pathogens inducing diseases on this...

A conserved rubredoxin is necessary for photosystem II accumulation in diverse oxygenic photoautotrophs

07/30/2013 00:00

Calderon RH, García-Cerdán JG, Malnoë A, Cook R, Russell JJ, Gaw C, Dent RM, de Vitry C, Niyogi KK. Abstract: In oxygenic photosynthesis, two photosystems work in tandem to harvest light energy and generate NADPH and ATP. Photosystem II (PSII), the protein-pigment complex that uses light...

Pathogen-associated molecular pattern-triggered immunity and resistance to the root pathogen Phytophthora parasitica in Arabidopsis

07/12/2013 00:00

Mathieu Larroque, Elodie Belmas, Thomas Martinez, Sophie Vergnes, Nathalie Ladouce, Claude Lafitte, Elodie Gaulin and Bernard Dumas Abstract: The cellulose binding elicitor lectin (CBEL) of the genus Phytophthora induces necrosis and immune responses in several plant species, including...

Post mortem function of AtMC9 in xylem vessel elements

07/08/2013 00:00

Benjamin Bollhöner, Bo Zhang, Simon Stael, Nicolas Denancé, Kirk Overmyer, Deborah Goffner, Frank Van Breusegem, Hannele Tuominen Abstract: Cell death of xylem elements is manifested by rupture of the tonoplast and subsequent autolysis of the cellular contents. Metacaspases have been...

Calcium/calmodulin-mediated regulation of plant immunity

07/01/2013 00:00

Cécilia Cheval, Didier Aldon, Jean-Philippe Galaud and Benoît Ranty Abstract: Calcium is a universal messenger involved in the modulation of diverse developmental and adaptive processes in response to various physiological stimuli. Ca2 + signals are represented by stimulus-specific...

06/28/2013 00:00

Fliegmann J, Canova S, Lachaud C, Uhlenbroich S, Gasciolli V, Pichereaux C, Rossignol M, Rosenberg C, Cumener M, Pitorre D, Lefebvre B, Gough C, Samain E, Fort S, Driguez H, Vauzeilles B, Beau JM, Nurisso A, Imberty A, Cullimore J, Bono JJ. Abstract: While chitooligosaccharides (COs) derived...

Interactions of beneficial and detrimental root-colonizing filamentous microbes with plant hosts

06/25/2013 00:00

Thomas Rey and Sebastian Schornack Abstract: Understanding commonalities and differences of how symbiotic and parasitic microbes interact with plants will improve advantageous interactions and allow pathogen control strategies in crops. Recently established systems enable studies of root...
