The main goal of this facility is to offer expertise to develop new protocols and to carry out the measurement and analysis of plant metabolites using a combination of isotopic and metabolomic techniques. We have the tools and know-how to undertake the rapid metabolic phenotyping of plant lines to help understand the consequences of specific genetic mutations with respect to metabolite contents, and to allow the determination of carbon, nitrogen and water use efficiencies as well as fluxes in plant organs and terrestrial vegetation. Analyses are performed by the Platform staff using the adequate protocols and technologies including semi-targeted metabolomics by GC-MS or NMR 1H ; isotope analyses of total organic matter (EA-IRMS), gases (GC-IRMS) and extracts (LC-IRMS) ; analyses of cofactors (by LC-MS) and amino acids (by HPLC), metabolites tracing by NMR (13C or 15N).
The facility is not only involved in local research projects since it is open to other laboratories whether they are public or private, local, national or international. This is achieved either as a service or collaboration and in both cases the Platform offers expertise from the experimental design to a statistical analysis of the data. Over the years, the platform has become a leader in European metabolomics and it has developed innovative techniques including the simultaneous determination of metabolomics and 13C-NMR-based changes in primary metabolites (Bathellier et al 2009) ; the application of TBDMS-derivatization and 13C-IRMS to analyse δ13C value of soluble sugars (Mauve et al 2009) ; an LC-MS method for cofactors and nucleotides (Guérard et al 2011).
