11. 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

12. Variables limiting efficacy of slow filters integrated into closed hydroponic growing systems
Abstract : For sustainable production of greenhouse vegetables and ornamentals, losses of water and nutrients must be avoided. Closed hydroponic systems are highly efficient in their use of water and nutrients, produce high yields and minimise the needs for soil sterilization. READ MORE

13. Size matters : RNA silencing processes in Phytophthora infestans
Abstract : Non-coding RNAs do not encode proteins but instead function through their own RNA sequence. These molecules range from several thousands of nucleotides (nt) in length down to around 20 nt. Specifically, small RNAs (sRNAs) have critical functions in eukaryotic cells, despite being only 20-30 nt long. READ MORE

14. Differentiation and Pathogenicity within the Saprolegniaceae : Studies on Physiology and Gene Expression Patterns in Saprolegnia parasitica and Aphanomyces astaci
Abstract : Saprolegnia parasitica and Aphanomyces astaci are parasitic water moulds belonging to the Oomycetes. Despite their importance as parasites they are very little studied at the molecular level and the work described in this thesis was aimed at increasing the molecular knowledge of these organisms by cloning and characterising genes of potential importance for reproduction and pathogenicity.

15. Mechanism of Action of the Plant Growth Promoting Bacterium Paenibacillus polymyxa
Abstract : Paenibacillus polymyxa belongs to the group of plant growth promoting rhizobacteria (PGPR). Activities associated with P. polymyxa-treatment of plants in earlier experiments include, e.g. READ MORE
