Physiology, Ecology and Environment (P2E)

The laboratory is organised into three teams on the campus of the University of Orléans. The "Trees and Responses to Water and Environmental Constraints" team is interested in the physiological mechanisms involved in tree acclimation and adaptation to drought, the molecular mechanisms of poplar plasticity to variations in soil water availability, in particular through an epigenetic approach, and the use of plants for phytomanagement  on soils contaminated by heavy metals. The second team, 'Cellular Signalling’ is working on the signalling pathway involved in the perception and transduction of the signal generated by water stress in poplar. The third team, 'Entomology and Integrated Biology', is studying the behavioural and cellular mechanisms of insects in the face of environmental pollutants and the interspecific (communities) and intraspecific (population genetics) biodiversity of insects, in relation to global change.
