Team 1

Team 1 brings together research skills on plants (physiology, ecophysiology, enzymology, genetics, phenotyping) present on the sites of the Universities of Amiens, Liège and Lille as well as on the INRAE site of Estrées-Mons. The team's research concerns 2 research axes:

  1. the understanding of the mechanisms which determine on the one hand the tolerance of plants to abiotic stresses (temperature, water) and on the other hand the efficiency of use of the mineral elements (nitrogen, phosphorus);
  2. the improvement of plants intended for the production of molecules of high added value.

The competences of the team make it possible to combine biological research questions (understanding the physiological mechanisms and genetic determinants of phenology, resource acquisition and stress tolerance) with methodological question, in particular questions of instrumentation of phenotyping. The characters are studied at scales varying from the gene to the whole plant in its environment. The main agronomic models targeted are miscanthus, corn, wheat and peas.

Team1

For these species, the work that has been carried out has applied objectives in terms of cultural management and / or selection. The research questions of the 2 axes are approached by paying particular attention to the role of the composition and the structure of the plant wall. The model Arabidopsis is taken into account at this level for the study of the biochemical characteristics of the enzymes that remodel the plant wall.
