11. Long-term phosphorus supply in agricultural soils : size and dynamics of fast- and slow-desorbing phosphorus pools
Abstract : To improve phosphorus (P) fertiliser management, a better understanding of inorganic P exchange between the soil solution and solid phase is needed. This thesis examined the dynamics of this exchange, distinguishing between pools of P that are fast- and slowdesorbing, and compared methods for quantification of these pools. READ MORE

12. Where have all the forests gone? Quantifying pantropical deforestation drivers
Abstract : Deforestation across the tropics continues to be a major source of greenhouse gas emissions and the largest threat to biodiversity on land. With strengthened commitments to reduce deforestation from countries and companies alike, it is crucial that renewed investments for reducing deforestation be guided by a sound understanding of what drives deforestation.

13. Characterization of chromatin mobility upon DNA damage in Arabidopsis thaliana
Abstract : Plant cells are subject to high levels of DNA damage from dependence on sunlight for energy and the associated exposure to biotic and abiotic stresses. Double-strand breaks (DSBs) are a particularly deleterious type of DNA damage, potentially leading to chromosome rearrangements or loss of entire chromosome arms. READ MORE

14. Host-pathogen interactions in root infecting oomycete species
Abstract : The oomycetes include some of the most devastating pathogens on both cultivated crops and wild plants. In the genus Phytophthora some closely related species have a broad host range, while others are very host specific. READ MORE

15. Aggregation of gluten proteins - from wheat seed biology to hydrogels : scientific modelling based primarily on Monte-Carlo and HPLC methods
Abstract : Gluten proteins are intrinsically disordered proteins that form extensive aggregated networks in wheat seeds, where they are stored as a nutrient source for the embryo. A modelling approach involving computational biology with Monte-Carlo algorithms and wet laboratory studies, including HPLC analysis, was applied to unravel the aggregational and hydrogelforming properties of the gluten proteins.
