|Plant cell wall, function and utilization|
The activities of the department « Plant cell wall, function and utilization » (with the french abbreviation PAVE) are focused on the synthesis and utilization of the plant cell wall. Research groups of the department work on biological models as Arabidopsis thaliana and Brachypodium distachyon, as well as maize. In addition to genetics and functional genomics approaches that are shared with the other departments of the Institute, the PAVE research groups use a broad variety of other approaches: quantitative live cell microscopy, biochemistry, analytical and synthetic chemistry, biophysics, biomimetic systems and modeling. The applied objectives of PAVE are the improvement of non-food usage properties of crop plants. This includes improving plant biomass composition for its utilization as renewable source of energy field, fibers and synthons for green chemistry.
The «Lignocellulosic biopolymers: from cell wall assemblies to synthons for green chemistry (Apsynth) » team studies the structure of native, industrial or synthetic lignins using analytical chemistry methods (degradation, liquid chromatography-mass spectroscopy LC-MS). Chemical mechanisms of biosynthesis and specifically plant induced structures are also worked. Maize genes involved in its biosynthesis are looked for as a model. Assembling properties with other parietal polymers and its possible valorizations in biomaterial field i.e.- hydrophobation surface agents (hydrophobation of starch films) or functionalised polymers with modified used properties using physical chemistry or biocatalysis are studied.
The « Primary cell wall » team studies the biosynthesis of the cell wall of growing cells and emphasizes on cellulose synthesis, pectins metabolism and coordination between parietal compounds and growth. The group uses plant nmodels as Arabidopsis thaliana and Brachypodium distachyon, and also agronomically and/or industrially important crops as Zea mays (maize).
The « Secondary Cell Wall » team studies mainly plant lignification from the biosynthesis of precursors (the monolignols) in the cytoplasm to the transportation and polymerization in the cell wall. This team uses Arabidopsis thaliana and Brachypodium distachyon as model plants. The group is in charge of the constitution of a chemically mutagenized Brachypodium mutant collection. This collection is used to identify cell wall mutants by forward or reverse genetics (TILLING).
The « Biommass quality and drought response " team was founded in 2012. The objective is to identify the parameters that impact the establishment of lignocellulosic biomass and that are decisive for its valorization, whether or not plants undergo drought stress.
