Major Research Interests

Molecular Ecophysiology of Stress Adaptation in Trees
We investigate molecular and physiological responses of trees to stress and to globally changing environmental conditions. The major model is Populus, whose genome has been sequenced. Other tree species or Arabidopsis are also used as models. Molecular and physiological networks involved in defence responses (salt, heavy metals) and internal resource reallocation (nitrogen) are studied by expressional profiling and functional characterisation.

Biotic Interactions
Temperate forest tree species generally form symbiotic associations with ectomycorrhizal fungi, which provide water and nutrients to the trees and obtain in exchange carbohydrates for their own growth. Fungal diversity is investigated at the molecular level. Functional analysis employs stable isotope labelling and physiological studies in axenic fungus-plant systems.

Apoplast and Cell Walls
Abiotic stress factors as well as changing environmental conditions and interaction with biotic factors (symbiotic and pathogenic fungi) affect wood formation and technological properties. In signal transduction and final response (changes in wood anatomy and chemistry) the apopast is of central importance. We are particularly interested in apoplastic redox systems (antioxidants) and wall formation.
