1. 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.

2. Computational Problems in Modeling Evolution and Inferring Gene Families
Sammanfattning : Over the last few decades, phylogenetics has emerged as a very promising field, facilitating a comparative framework to explain the genetic relationships among all the living organisms on earth. These genetic relationships are typically represented by a bifurcating phylogenetic tree — the tree of life. LÄS MER
3. Hidden Diversity Revealed : Genomic, Transcriptomic and Functional Studies of Diplomonads
Sammanfattning : The diplomonads are a diverse group of eukaryotic microbes found in oxygen limited environments such as the intestine of animals were they may cause severe disease. Among them, the prominent human parasite Giardia intestinalis non-invasively colonizes the small intestine of humans and animals where it induces the gastrointestinal disease giardiasis. LÄS MER
4. Co-operative recombination mechanisms promoting gene clustering and lateral transfer of antibacterial drug resistance
Sammanfattning : Transposons of the Mu superfamily are widespread and have been shown to play an important role in the dissemination of antibiotic resistance among microorganisms. One of these elements, Tn5090/Tn402 is the basal vehicle of the type 1 integrons in which mobile resistance gene cassettes are inserted to form clusters and operons. LÄS MER
5. Mechanisms and DNA Specificity in Site-specific Recombination of Integron Cassettes
Sammanfattning : Bacterial resistance to antibiotics has become a serious problem. This is due to the remarkable ability of bacteria to respond and rapidly adapt to environmental changes. Integrons are elements with the capacity for gene capture by an integron-encoded site-specific recombinase called IntI. LÄS MER
