Researchers at the Cell & Plant Physiology laboratory are studying the mechanisms that control flower development and analyzes the changes undergone by these regulators during evolution. The LEAFY protein (LFY) is a key regulator of floral development and according to evolutionary theories, would also be the major player behind the rise of flowering plants. Those researchers have just obtained the first 3-D structure of the binding domain of LEAFY to the DNA in the model plant Arabidopsis thaliana. By the mean of a biochemical approach confirmed by the structure, the team showed that the cooperative DNA/protein interaction could partly explain the ability of LEAFY to initiate the floral transition.
CEA is a French government-funded technological research organisation in four main areas: low-carbon energies, defense and security, information technologies and health technologies. A prominent player in the European Research Area, it is involved in setting up collaborative projects with many partners around the world.
