1. Lifestyle and Genome Evolution in Vector-Borne Bacteria : A Comparison of Three Bartonella Species
Abstract : Bacterial genomes provide records of the molecular processes associated with emergence and evolution of different bacterial lifestyles. This thesis is based on whole-genome comparisons within the genus Bartonella, an excellent model system for studies of host- and vector-specificity and infection outcome in animal-associated bacteria.

2. Mitochondrial and Eukaryotic Origins : A Phylogenetic Perspective
Abstract : Mitochondria are eukaryotic cellular organelles responsible for power-generation, believed to have come into existence by an endo-symbiontic event where a bacterial cell was incorporated by an un-specified "proto-eukaryote". Phylogenetic analysis have shown that the mitochondrial ancestor was most related to present-day alpha-proteobacteria, although the exact nature of the mitochondrial progenitor remains disputed.

3. On the antiporter-like subunits of respiratory chain Complex I - implications for the evolution and coupling mechanism of the NADH:quinone oxidoreductase enzyme complex
Abstract : Complex I or NADH:quinone oxidoreductase is the largest enzyme complex, but the least understood energy coupling site in the respiratory chain of mitochondria and bacteria. No high-resolution structural information exists for this enzyme and the molecular mechanism that couples electron transfer and proton pumping is not understood. READ MORE

4. Mapping the Rickettsia prowazekii genome
Abstract : Rickettsia prowazekii is a member of alpha proteobacteria and the etiologic agent of epidemictyphus. Besides its pathogenicity as an obligate intracellular parasite it has been considered as amodel organism in a variety of studies.We have established a collection of overlapping clones, covering nearly the complete R.prowazekii genome.
