1. Small RNAs, Big Consequences : Post-transcriptional Regulation and Adaptive Immunity in Bacteria
Sammanfattning : It is nowadays widely accepted that non-coding RNAs play important roles in post-transcriptional regulation of genes in all kingdoms of life. In bacteria, the largest group of RNA regulators are the small RNAs (sRNAs). LÄS MER
2. Small RNA-mediated Regulation of Gene Expression in Escherichia coli
Sammanfattning : Non-coding RNAs are highly abundant regulators of gene expression in all kingdoms of life that often play important roles in vital cellular functions. In bacteria, small regulatory RNAs (sRNAs) usually act post-transcriptionally by regulating mRNAs through base pairing within ribosome binding sites (RBS), thereby inhibiting translation initiation.

3. Multifaceted RNA-mediated regulatory mechanisms in Streptococcus pyogenes
Sammanfattning : Bacterial pathogens rely on precise regulation of gene expression to coordinate host infection processes and resist invasion by mobile genetic elements. An interconnected network of protein and RNA regulators dynamically controls the expression of virulence factors using a variety of mechanisms. LÄS MER
4. Cis-regulatory variation and divergence in Capsella
Sammanfattning : Cis-regulatory changes in e.g. promoters or enhancers that affect the expression of a linked focal gene have long been thought to be important for adaptation. In this thesis, I investigate the selective importance and genomic correlates of cis-regulatory variation and divergence in the genus Capsella, using massively parallel sequencing data. LÄS MER
5. Macromolecular Matchmaking : Mechanisms and Biology of Bacterial Small RNAs
Sammanfattning : Cells sense the properties of the surrounding environment and convert this information into changes in gene expression. Bacteria are, in contrast to many multi-cellular eukaryotes, remarkable in their ability to cope with rapid environmental changes and to endure harsh and extreme milieus. LÄS MER
