1. 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
2. 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.

3. Rates and patterns of genome evolution in Lepidoptera
Sammanfattning : The evolutionary consequences of genome restructuring and chromosomal rearrangements can be significant, but the underlying mechanisms are poorly understood. This thesis explores the relationships between genome restructuring, recombination, and maintenance of genetic diversity in different butterfly species. LÄS MER
4. The Gene Repertoire of G protein-coupled Receptors : New Genes, Phylogeny, and Evolution
Sammanfattning : The superfamily of G protein-coupled receptors (GPCRs) is one of the largest protein families of mammalian genomes and can be divided into five main families; Glutamate, Rhodopsin, Adhesion, Frizzled, and Secretin. GPCRs participate in most major physiological functions, contributing to the fact that they are important targets in drug discovery. LÄS MER
5. Evolution of symbiotic lineages and the origin of new traits
Sammanfattning : This thesis focuses on the genomic study of symbionts of two different groups of hymenopterans: bees and ants. Both groups of insects have major ecological impact, and investigating their microbiomes increases our understanding of their health, diversity and evolution. LÄS MER
