The activities of the SCSM department « Cell Structures, Signals and Morphogenesis » are focused on plant cell and its role in growth and vegetative development of higher plants. Research groups of the department work on biological models as Arabidopsis thaliana and Brachypodium distachyon, and also on agronomical and/or industrial important crops as pea, cotton and maize. Genetics and functional genomics approaches are widely shared with the other departments of the Institute Jean-Pierre Bourgin. Research groups mobilize a large variety of scientific fields and competences: imaging and dynamic microscopy, biochemistry, analytical and synthetic chemistry, biophysics, biomimetic systems, modelling. Finality of our research is to improve compatibility between vegetal resources and its use. This including improving the plant architecture and biomass composition with the possibility to be industrially processed. A special effort concerns application in the bioenergy field, vegetal fibers and green chemistry.
