Using a previous optimized protocol for the separation of proteins, the main focus of this thesis was the quantitative analysis of beech leaves proteins after long-term treatment with elevated ozone/CO2 concentrations. Following ozone treatment a large number of identified proteins involved in the Calvin cycle and photosynthesis were down-regulated while proteins from the carbon metabolism/catabolism, stress/defense response, and the detoxification system were up-regulated. Regarding the elevated CO2 treatment, beech saplings induced a down-regulation of two important proteins implicated in the CO2 fixation, most likely indicating the acclimation capacity of beech to higher CO2 levels. Finally, a relative mass spectrometry approach was carried out to identify proteomic signatures in water deprived Cenococcum geophilum isolates. Overall, these results uncovered evidence that differentially abundant proteins were involved in repair and defense reactions commonly induced by multiple stresses such as reactive oxygen species.
