1. Horizontal gene transfer in plants - The story of PgiC2
Sammanfattning : Sheep's fescue, Festuca ovina, is a common grass found all over Eurasia. In populations in southern Sweden some individuals were found to have two copies of the gene for cytoplasmic phosphoglucose isomerase, PgiC. LÄS MER
2. 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.

3. Horizontal gene transfer by uptake of apoptotic bodies
Sammanfattning : In adults as well as during embryogenesis, apoptosis plays a key role in the elimination of cells in multicellular organisms. Apoptosis is important for the maintenance of tissue homeostasis. It is also of importance in tumor development, where tumor cells die by apoptosis due to low levels of oxygen and nutrients. LÄS MER
4. Using Trees to Capture Reticulate Evolution : Lateral Gene Transfers and Cancer Progression
Sammanfattning : The historic relationship of species and genes are traditionally depicted using trees. However, not all evolutionary histories are adequately captured by bifurcating processes and an increasing amount of research is devoted towards using networks or network-like structures to capture evolutionary history.

5. Computational discovery of antibiotic resistance genes and their horizontal transfer
Sammanfattning : Antibiotic resistance is increasing among clinical infections and represents one of the most serious threats to public health. Pathogens often become resistant by acquiring mobile antibiotic resistance genes (ARGs) via horizontal gene transfer (HGT). LÄS MER
