16. Evolutionary Dynamics of Mutation and Gene Transfer in Bacteria
Sammanfattning : The study of bacterial evolution is fundamental for addressing current problems of antibiotic resistance and emerging infectious diseases and lays a solid foundation for successful and rational design in biotechnology and synthetic biology. The main aim of this thesis is to test evolutionary hypotheses, largely based on theoretical considerations and sequence analysis, by designing scenarios in a laboratory setting to obtain experimental data.

17. Advanced Metal Oxide Semiconductors for Solar Energy Harvesting and Solar Fuel Production
Sammanfattning : Increasing energy consumption and its environmental impacts make it necessary to look for alternative energy sources. Solar energy as huge energy source which is able to cover the terms sustainability is considered as a favorable alternative. LÄS MER
18. The genomic basis of the response to female-limited X-chromosome evolution
Sammanfattning : In this thesis, I attempted to achieve a better understanding of the nature of X-linked polymorphic loci using a female-limited X chromosome (FLX) experimental evolution in Drosophila melanogaster. I expected that expressing the evolved X chromosome will result in an increase in female fitness and a decrease in male fitness. LÄS MER
19. Evolution of the Neuropeptide Y and Opioid Systems and their Genomic Regions
Sammanfattning : Two whole genome duplications (2R) occurred early in vertebrate evolution. By using combined information from phylogenetic analyses and chromosomal location of genes, this thesis delineates the evolutionary history of two receptor-ligand systems that expanded by these large scale events.

20. Evolution of olfaction in Lepidoptera and Trichoptera : Gene families and antennal morphology
Sammanfattning : In moths, females produce sex pheromone compounds to attract males over a long distance for mating. The antennae of moths and many other insects have specialized odorant receptors (ORs), called pheromone receptors (PRs), to sense the pheromone compounds and they group in a monophyletic clade (PR clade).
