B&PMP, Biochemistry and Plant Molecular Physiology

B&PMP (Biochemistry and Plant Molecular Physiology) is defined as an Integrative Biology research department, focused on the mechanisms of plant responses and adaptation to variable abiotic environmental conditions. These last fifteen years, B&PMP has gained a strong scientific identity by unraveling the molecular mechanisms which contribute to determine the hydro-mineral balance of plants, subjected to various abiotic stresses. This has been made possible by integrating cellular, molecular, genetic, biochemical, biophysical and physiological approaches, and mainly by using the model plant Arabidopsis thaliana.

Research topics at B&PMP include:  

  •  Analyses of transport activities (transporters and channels) as well as mineral nutrition
  • Sensing, signalling and regulatory mechanisms driving the water-mineral status of plant
  • Developmental processes, in particular of the root system
  • Metabolic aspects linked to mineral utilisation, assimilation or toxicity
  • Diversification of plant models. Arabidopsis remains the major model plant studied at B&PMP, shared by all the research groups. However, other biological models (Pea, Medicago, rice, grape, metal hyperaccumulators ...etc), are commonly used

The teams of unit AGAP involved in the CultiVar project include :

  • Team Metal toxicity. The scientific objectives of our team are to identify and characterize mechanisms controlling (i) metal tolerance of plants and (ii) metal accumulation in plants.
  • Team Aquaporins. Research in the Aquaporin group aims at understanding the various modes and regulations of water transport in plant tissues.
