 42 persons: 5 Professors, 15 Lecturers, 12 Technicians and 10 PhD students
 3 teams on two sites: Orléans and Chartres
Team 1 Orléans
Team 2 Orléans
Team 3 Chartres
Responses of Trees to
Drought and Environmental
Constraints
Forest Entomology
(Tree insects relationships)
Lignans of Flaxes
 Thematics
Orléans’ teams focus on tree-environment interactions with
poplar as model. Poplar is a fast growing tree of high economical
interest and its genome has been sequenced. The abiotic factors
are studied by Team 1 working on water availability; biotic
factors are developed by Team 2 mainly on aphids. These
activities are complementary to those developed at INRA
(National Institute for Agronomical Research) and are in full
accordance with the priorities defined by local politics and the
competitiveness cluster ‘DREAM Eau & Milieux’.
Chartres’ team (Team 3) works on lignan metabolism regulation.
Flax lignans are compounds of medical and cosmetic interests
due to their phyto-oestrogenic and antioxidant properties.
Chartres area harbours a number of cosmetic and
pharmaceutical companies.
