2. Studies of Functional Interactions within Yeast Mediator and a Proposed Novel Mechanism for Regulation of Gene Expression
Abstract : The yeast Mediator complex is required for transcriptional regulation both in vivo and in vitro and the identification of similar complexes from metazoans indicates that its function is conserved through evolution. Mediator subunit composition and structure is well characterized both by biochemical, genetic and biophysical methods. READ MORE

3. Dynamics of the Bacterial Genome : Rates and Mechanisms of Mutation
Abstract : Bacterial chromosomes are highly dynamic, continuously changing with respect to gene content and size via a number of processes, including deletions that result in gene loss. How deletions form and at what rates has been the focus of this thesis. In paper II we investigated how chromosomal location affects chromosomal deletion rates in S. READ MORE

4. Regulatory mechanisms involved in pathoadaptation of extraintestinal pathogenic Escherichia coli
Abstract : Establishment of commensal bacteria within a new niche of their host usually promotes the transition from commensalism to pathogenicity. Extraintestinal Pathogenic Escherichia coli (ExPEC) represent different pathovars with biphasic lifestyle – they can reside in the gut as commensals or they can escape and cause diseases elsewhere in the human body.
