[May 9, 2012] Dr Pascale de Lonlay from the Hôpital Necker-enfants malades in Paris gave in the lab this morning a very interesting talk on the autosomal recessive LPIN1 mutations recently described as a novel cause of rhabdomyolysis in few families. This protein is likely links with disorder of the lipid metabolism. Dr de Lonlay was invited by Eric Testet to discuss a collaboration with the LBM and the lipidomic platform.

[May 9, 2012] Ian Pulsifer from Pr O. Rowland’s lab at Carleton University (Ottawa, Canada) is visiting us for 10 days. He is supported by a FCRF grant (France Canada Research Fund) obtained by F. Domergue and O. Rowland. Ian will express Arabidopsis proteins in E. coli and characterize the compounds resulting from their expression by GC-MS. Have fun in Bordeaux!!



[May 7, 2012] "Lipids of plant membrane rafts". This is the title of our recent invited review published in Progress in Lipid Research (http://dx.doi.org/10.1016/j.plipres.2012.04.001). As stated, this article wrote conjointly by members of the "Biomembranes and Membrane Lipids" reviews the current knowledge and perspectives on phospholipids, sphingolipids and phytosterols in plant raft microdomains going from model membranes to vizualisation and cellular functions.



ANOUNCEMENT: After the successful "Patchy Prague 2010", comes now "Dijon Domains 2012" https://colloque.inra.fr/dijon_domains
This conference, which will be held in Dijon from 27 to 30 November 2012,  will be dedicated to the most advanced methodologies allowing the study of membrane sub-compartmentation, the latest exciting discoveries concerning the characterization of membrane organization, and the most recent evidences indicating a crucial role of this organization and its dynamics in signaling processes and cell physiology.
Very famous speakers accepted the invitation in Dijon like Kai Simons, Erwin London, Luis Bagatolli, Katharina Gaus, Didier Marguet, Bridget Wilson, Tobias Walther and will give plenary invited lectures

[April 18, 2012] We were glad to hear the talk of Federica Brandizzi from Michigan State University, USA (http://www.prl.msu.edu/Facultypages/Brandizzi.html) on news and views in the activities of the plant Endoplasmic Reticulum. Federica whose is a close collaborator of Patrick Moreau from the LBM, was invited by our lab and the SFR "Biologie Intégrative et Ecologie".
Thank you Fede', for the visit, see you soon.



[Avril 18, 2012]  The project « MetaboHub » which aims to coordinate metabolomic researches between labelled IBISA platforms in Bordeaux (Metabolome : INRA, Bordeaux University), Paris (MetabolomeIDF, Paris-Saclay, CEA and Pierre and Marie Curie University), 
Toulouse (MetaToul, Paul Sabatier University, INSA, INRA, CNRS and INSERM), and Clermont-Ferrand (Exploration du Métabolisme, INRA and Blaise Pascal University) has been funded. The lipidomic platform in which several members of the LBM are implicated will be largely involved in the future development of new MS/MS lipid methodologies.

 

[Avril 16, 2012] Since the 1st of January 2012, ADERA (Association pour le Développement de l'Enseignement et des Recherches auprès des universités, des centres de recherche et des entreprises d'Aquitaine) created a technology transfer unit leaned back on our UMR (http://www.adera.fr/spip.php?article32). Its name: LEB Aquitaine Transfert, LEB stating for "Lipids, Environment and Biotechnologies". The main missions are to provide expertise and conduct research works in two distinct areas: 1/ Ecotoxicology (using the lipids as diagnostic tools), and 2/ Biotechnology of lipids of industrial interest.  Marina Le Guédard (Engineer-PhD) is the R&D responsible.



[March 30 , 2012]  Emmanuelle Bayer, member of the raft team at the LBM, has recently published with her former group in Bern Switzerland, headed by R. Smith and C. Kuhlemeier a paper published in Science. This work shows for the first time that mechanical signals are not just passive readouts of gene action but can feed back on morphogenesis.




[March 6-7 , 2012] Laetitia Fouillen came back from the 2nd Graz Lipid Mass Spec Meeting where she had the chance to learn and talk with lipid mass spec specialists. She presented a poster on the variability of fatty acid and TAGs compositions in palm oil using lipidomics.


[Mars 1, 2012] The LBM welcome several students : two M2 students,
Camille Delude who is working with Fred Domergue in the wax team and Etienne Legrand who is working on palm oil synthesis with Vincent Arondel; two M1 students, Simon Vanderliden with Claire Bréhelin and Julien Gronnier with Jérôme Joubès.

[February 6, 2012]

[November 22, 2011] The famous “coffee NDR1” paper finally got accepted into BMC Plant Biology upon a long-lasting review process. Congratulations to all authors… and think of it when you have a coffee break! "Identification and characterization of the Non-race specific Disease Resistance 1 (NDR1) orthologous protein in coffee". Cacas JL, Petitot AS, Bernier L, Estevan J, Conejero G, Mongrand S, Fernandez D. BMC Plant Biol, Oct 24;11:144.

[November 21, 2011] The evaluation of the toxic effects of pollutants is difficult to grasp in a real and complex environment. We recently evidenced using Lactuca serriola that plant leaf fatty acid composition measured in situ would provide an early indication of a plant’s exposure to metal and could be used as a reliable tool to facilitate or strengthen the diagnosis of soil contamination.
Le Guédard et al (2012). Env. Exp. Bot,76, 54-59.


We recently characterized a new lyso-PA acyltransferase regulating the amount of triglycerides (TG) in S. cerevisiae. Using a lipidomic approach (HPTLC-GC; MS/MS) we demonstrated that this enzyme is responsible for the incorporation of oleic acid both in phospholipids and TG, whereas quantitatively only TG were decreased in mutant cells. In addition we showed by immunoblot, proteomic and confocal studies that this enzyme is mainly located in ER membranes and in lipid droplets during the exponential and the stationary phases respectively.
Ayciriex et al. (2012) Mol Biol Cell, in press



[November 17 and 18, 2011] We are hosting Drs Martine Devic and Thomas Roscoe from the Epigenetic Regulation and Seed Development Group, IRD, Montpellier. They did experiments to determine the lipid composition changes of different mutants of Arabidopsis thaliana and presented their results.
