B&PMP (Biochemistry and Plant Molecular Physiology) is a Joint Research Unit supported by four institutions : CNRS, INRA, SupAgro, and the University of Montpellier. Its research activity aims at elucidating the fundamental mechanisms that govern the water and mineral nutrition of plants, and their responses to abiotic environmental constraints, including those due to climate change.

Our objective is dual : to understand better the organization and functioning of plants ; to contribute to the development of a sustainable agriculture, that saves natural resources and respects the environment.

For this, we develop an Integrative Biology approach. We combine multidisciplinary (genomics, biophysics, molecular biology, modelling) and multiscale (from gene to whole plant) approaches on various plant species (model and crop plants). Our projects address how the development and physiological functions of organs are coordinated, with an especially recognized expertise on roots. The aim is to determine how this coordination leads to an integrated response of plants to environmental constraints and how it governs plant growth.

Highlights

White lupin: The genome of this legume has finally been sequenced

White lupin has a root system that is highly adapted for poor soils thanks to its proteoid or cluster roots, which allow it to extract phosphate from the soil very effectively. The mapping of its genome represents a major step toward understanding this mechanism.

Resources and soil life: better management for crop performance

November 12, 2019. Visit of the BPMP laboratory platform specialized in hydromineral plant nutrition and “Science-to-business” meetings in the afternoon between researchers and companies to give free rein to your questions and discuss your R&D issues.

Developmental control of plant Rho GTPase nano-organization by the lipid phosphatidylserine

Phosphatidylserine is required for the clustering of ROP6, a small guanosine triphosphatase (GTPase), in membranes in response to signals from the plant hormone auxin. Changes in phosphatidylserine concentration altered the clustering of ROP6 and thus the auxin signaling response
