11. Comparative Genomics of Obligate and Facultative Intracellular Parasites
Abstract : The α-proteobacteria Rickettsia prowazekii and Bartonella henselae are the causative agents of epidemic typhus and cat scratch disease respectively. Whereas R. prowazekii is an obligate intracellular parasite, B. henselae can live and proliferate both outside and inside the eukaryotic host cell. READ MORE

12. Biology of a small RNA virus that infects Drosophila melanogaster
Abstract : Drosophila melanogaster has been extensively used as a model organism to study diverse facets of biology, including host-pathogen interactions and the basic biology of its pathogens. I have used the fruit fly as a model to study elementary aspects of Nora virus biology, such as the role of the different proteins encoded by the virus genome. READ MORE

13. Comparative Genomics in Diplomonads : Lifestyle Variations Revealed at Genetic Level
Abstract : As sequencing technologies advance genome studies are becoming a basic tool for studying an organism, and with more genomes available comparative genomics is maturing into a powerful tool for biological research. This thesis demonstrates the strength of a comparative genomics approach on a group of understudied eukaryotes, the diplomonads. READ MORE

14. Studies of the Carbon and Energy Metabolism in the Moss Physcomitrella patens
Abstract : Since a proper balance between anabolic and catabolic reactions is essential for all eukaryotes, the basic mechanisms for regulation of the energy and carbon metabolism have been conserved throughout evolution. The moss Physcomitrella patens, which belongs to one of the basal clades among land plants, has many unique properties that make it an excellent plant model system. READ MORE

15. Ancient roles of non-coding RNAs in eukaryotic evolution : contributions from social amoebae and other protists
Abstract : RNAs not coding for proteins, non-coding RNAs (ncRNAs) have many important roles in all kingdoms of life. Especially in eukaryotes, the regulatory functions of ncRNAs have been suggested as a major force in the evolution of complex traits. READ MORE
