[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.

[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.

[September, 2011] Welcome to Agnès Chevin the new administrator of the lab.

[November 2, 2011] ICON strikes again!!! Collaboration between labs from Sweden, Canada, Australia and the LBM, all partners of the large collaborative project ICON (http://icon.slu.se/ICON/index.htm), resulted in the in vitro functional characterization of the plastidial fatty acid reductase AtFAR6. Have a look at its unexpected catalytic capacities in our  "Publications" section.!!!

[October 21, 2011] Do not forget two importante dates for the lab, Rémi from the "Storage lipid metabolism" team will defend his thesis Thursday November 10th and Amélie  from the "wax" team will defend her thesis Friday December 9th.

[October 1, 2011] Sébastien Mongrand has been nominated at the section 28 "Biologie végétale intégrative" of the comité national. http://www.cnrs.fr/comitenational/sections/section28.htm

[September 27, 2011] Rene Lessire was in Rotterdam, as a member of the scientific committee of the 9th EuroFed Lipid Congress “Oil, Fats and Lipids for a Healthy and Sustainable World” with more than 600 participants,150 lectures and 250 posters. René was chairman of the “Oilseeds, Plant breeding, Plant lipids” session and he presented a lecture on Arabidopsis CER1, the function of  which has been recently elucidated by Amélie Bernard and her collegues.

[September 22, 2011] Patrick Moreau came back from The Society for Experimental Biology SEB meeting « Exocytosis in animals, fungi and plants »   organized in London by Viktor Zarsky (University of Praha), and where he gave a conference on “Links between lipid biosynthesis, organelle morphology and protein trafficking in plant secretory pathways”. This meeting gave a large part to plant research and exciting comparisons were discussed between plant cells and other eukaryotic models. This SEB symposium was also the opportunity to estimate that plant fields have reached similar levels of excellence than their mammal and yeast counterparts. The program of the symposium can be obtained at the SEB meeting site (http://www.sebiology.org/meetings/Exocytosis/index.html).



[September 12,  2011] Check our new review on Plant Rafts in Current Opinion in Plant Biology by the raft team (Sébastien, Artemis and Emmanuelle) together with our collaborators from Dijon, Françoise Simon-Plas and Patricia Gerbeau-Pissot. We discuss a working model of the putative involvement of rafts in the activation of RbohD after elicitation by PAMP.
This article is now published online at: http://dx.doi.org/10.1016/j.pbi.2011.08.003
Keep also track of lab updates publication with the "Activités" section.


[September 8, 2011] Have  a look at our last publication in PNAS, written with our swiss friends from Neuchâtel co-written by Claire Bréhélin from the LBM, about the plastoglobule localized enzyme AtNDC1 (a type II NADPH quinone oxidoreductase) and its role in plastoquinone oxidoreduction and prenylquinone metabolism. http://www.pnas.org/content/108/34/14354.long
Beside, all you always dreamt to know about Arabidopsis plastoglobule preparation is explained by Claire and her colleagues in this new chapter of Methods in Molecular Biology.

Our collaborator Alicia Zelada welcomed us to work on PVX propagation and the involvement of the plant raft protein REMORIN (bottom left picture, from left to right: Maria BINAGHI, Sébastien MONGRAND, Alicia ZELADA and Artemis PERRAKI).
We took the opportunity to visit Iguaçu Falls and the city of Buenos Aires and its strange baobabs…


[July 18, 2011] We're back from Gdansk in Poland where the 5th european Symposium on Plant Lipids took place. As always, the congress was very interesting, we met lot of colleagues and several people from the lab had the opportunities to present their work (Amélie, Vincent, Fred, Rémi and Jérôme).



[June 27, 2011] Jean-Jacques Bessoule et Marina Le-Guedard came back from the island of Skiathos in Greece. Lucky you ! They attended the Third International CEMPE (Conference on Environmental Management , Engineering, Planning and Economics)  and SECOTOX (Society of Ecotoxicology and Environmental Safety and its Regional Sections) conferences.  An utmost interested congress dedicated to environment and ecotoxicology.


[June 28, 2011] Our Laboratory (Oil group led by V. Arondel), in collaboration with John Ohlrogge's laboratory (MSU, USA) and two African scientists, has given a major contribution to a carbon partitioning study in palm mesocarps, which is now out in PNAS. Aside from its fundamental interest, this work opens the way to genetic improvement of oil palm, a major crop that grows almost exclusively in developing countries, with probable important long-term impact on development of these countries' agriculture.
