1. Monitoring climate and plant physiology using deuterium isotopomers of carbohydrates
Abstract : Climate is changing and it is certain that this change is due to human activities. Atmospheric greenhouse gases have been rising in an unprecedented way during the last two centuries, although the land biosphere has dampened their increase by absorbing CO2 emitted by anthropogenic activities.

2. Conservation of transcription factors in infected cells of nitrogen-fixing root nodules
Abstract : Infected cells of nitrogen-fixing root nodules are the only plant cells that can stably internally accommodate a eubacterial symbiont. In the context of studying the differentiation of infected cells, we set about to analyse the conservation of infected cell-specific transcription factors using altogether four different promoters from genes showing infected cell-specific expression, or nodule-specific expression.

3. Variability and adaptation in the contractile system of smooth muscle
Abstract : This thesis examines the cellular and molecular mechanisms involved in the large diversity of the contractile properties in smooth muscle. Six studies, I-VI, are included. I: a slow smooth muscle (aorta) has a different nucleotide and phosphate dependence compared to a fast type (taenia coli). READ MORE

4. Evolution of Plants : a mathematical perspective
Abstract : The Earth harbors around 300 000 plant species. The rich and complex environment provided by plants is considered a key factor for the extraordinary diversity of the terrestrial fauna by, for example, providing food and shelter. READ MORE

5. 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
