1. Systematics in Sileneae (Caryophyllaceae) – Taxonomy and Phylogenetic patterns
Sammanfattning : The focus for the first part of the thesis is on the systematics of species belonging to Silene subgenus Silene. Phylogenetic relationships are inferred from DNA sequences from both the plastid (the rps16 intron) and the nuclear (ITS, intron of the RPB2 gene) genomes. LÄS MER
2. Actin and myosin in transcription and chromatin regulation
Sammanfattning : In mammalian cells, actin and myosin have emerged as regulators of nuclear structure and function, involved in chromatin remodeling and histone modifications, and in different phases of gene transcription. Actin and myosin have also been shown to be incorporated into nascent ribonucleoprotein complexes. LÄS MER
3. The Role of the Escherichia coli RNA Polymerase β´Jaw in Transcription
Sammanfattning : Transcription, the central step in gene expression and regulation, is carried out by the DNA-dependent RNA polymerase (RNAP). Bacterial RNAP is a complex molecular machine in which the network of interacting parts and their movements, including contacts to nascent RNA and the DNA template, are at best partially understood.

4. From protein production to genome evolution in Escherichia coli
Sammanfattning : The aim of my Ph.D. studies was to improve production yields of membrane- and secretory proteins in the widely used E. coli protein production strain BL21(DE3). LÄS MER
5. Genetics and Growth Regulation in Salmonella enterica
Sammanfattning : Most free-living bacteria will encounter different environments and it is therefore critical to be able to rapidly adjust to new growth conditions in order to be competitively successful. Responding to changes requires efficient gene regulation in terms of transcription, RNA stability, translation and post-translational modifications. LÄS MER
