1. Mitochondrial Evolution : Turning Bugs into Features
Sammanfattning : The bacterial origin of mitochondria from an ancient endosymbiosis is now widely accepted and the mitochondrial ancestor is generally believed to belong to the bacterial subdivision α-proteobacteria. The high fraction of mitochondrial proteins encoded in the nucleus has commonly been explained with a massive transfer of genes from the genome of the ancestral mitochondrion. LÄS MER
2. Expanding the Chlamydiae tree : Insights into genome diversity and evolution
Sammanfattning : Chlamydiae is a phylum of obligate intracellular bacteria. They have a conserved lifecycle and infect eukaryotic hosts, ranging from animals to amoeba. Chlamydiae includes pathogens, and is well-studied from a medical perspective. LÄS MER
3. Multi-omics investigation into bacterial evolution
Sammanfattning : The focus of this thesis is the investigation of the evolution and cellular processes of Tuwongella immobilis and Apilactobacillus kunkeei, two bacterial species with different levels of genomic and cellular complexity, using a multi-omics approach.In the first study we examined the proteome of T.

4. Genome evolution of a bee-associated bacterium
Sammanfattning : The use of large-scale comparative genomics allows us to explore the genetic diversity and mechanisms of evolution of related organisms. This thesis has focused on the application of such approaches to study Lactobacillus kunkeei, a bacterial inhabitant of the honeybee gut.We produced 102 novel complete genomes from L. LÄS MER
5. Evolution of Vertebrate Endocrine and Neuronal Gene Families : Focus on Pituitary and Retina
Sammanfattning : The duplication of genes followed by selection is perhaps the most prominent way in which molecular biological systems gain multiplicity, diversity and functional complexity in evolution. Whole genome duplications (WGDs) therefore have the potential of generating an extraordinary amount of evolutionary innovation. LÄS MER
