1. Shedding Light on Shade- and Dark-Induced Leaf Senescence
Abstract : Leaf senescence is the final stage of leaf development, during which the leaf relocates most of itsvaluable nutrients to developing or storing parts of the plant. As this process progresses, leaves losetheir green color and their capacity to perform photosynthesis. READ MORE

2. Roles of LESIONS SIMULATING DISEASE1 and Salicylic Acid in Acclimation of Plants to Environmental Cues : Redox Homeostasis and physiological processes underlying plants responses to biotic and abiotic challenges
Abstract : In the natural environment plants are confronted to a multitude of biotic and abiotic stress factors that must be perceived, transduced, integrated and signaled in order to achieve a successful acclimation that will secure survival and reproduction. Plants have to deal with excess excitation energy (EEE) when the amount of absorbed light energy is exceeding that needed for photosynthetic CO2 assimilation. READ MORE

3. Intramolecular isotope analysis reveals plant ecophysiological signals covering multiple timescales
Abstract : Our societies' wellbeing relies on stable and healthy environments. However, our current lifestyles, growth-oriented economic policies and the population explosion are leading to potentially catastrophic degradation of ecosystems and progressive disruption of food chains. READ MORE

4. Regulatory proteolysis of higher plant thylakoid membranes : the significance of protein degradation in light acclimation of the photosynthetic apparatus
Abstract : Although the acclimation of plants to light condition has been known and extensively described for many years the underlying mechanisms have remained largely unsolved. In this thesis I present new experimental data and a model for the mechanism behind acclimation of mature higher plants to increased light intensities. READ MORE

5. How could Christmas trees remain evergreen? : photosynthetic acclimation of Scots pine and Norway spruce needles during winter
Abstract : Plants and other green organisms harvest sunlight by green chlorophyll pigments and covertit to chemical energy (sugars) and oxygen in a process called photosynthesis providing the foundation for life on Earth. Although it is unanimously believed that oceanic phytoplanktons are the main contributors to the global photosynthesis, the contribution of coniferous boreal forests distributed across vast regions of the northern hemisphere cannot be undermined.
