  2. 1. Systematics in Sileneae (Caryophyllaceae) – Taxonomy and Phylogenetic patterns

    Author : Frida Eggens; Bengt Oxelman; Magnus Lidén; Susan R. Kephart; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sileneae; Silene; RNAP; psbE-petG; ITS; rps16; relative dating; Rigidulae; Heliosperma; Arenosae; phylogeny; homoploid reticulate evolution; Silene linearis Decne.; Silene polyphylla L.; Hawaiian Silene; Systematics and phylogenetics; Systematik och fylogeni;

    Abstract : 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. READ MORE

  4. 2. Actin and myosin in transcription and chromatin regulation

    Author : Bader Almuzzaini; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : 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. READ MORE

  5. 3. The Role of the Escherichia coli RNA Polymerase β´Jaw in Transcription

    Author : Josefine Ederth; Leif A Isaksson; Anne Farewell; Stockholms universitet; []
    Keywords : mikrobiologi;

    Abstract : 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.

  6. 4. From protein production to genome evolution in Escherichia coli

    Author : Susan Schlegel; Jan-Willem de Gier; Peter Neubauer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Escherichia coli; BL21 DE3 ; protein production; membrane proteins; secretory proteins; genome evolution; Biochemistry; biokemi;

    Abstract : 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). READ MORE

  7. 5. Genetics and Growth Regulation in Salmonella enterica

    Author : Jessica M. Bergman; Diarmaid Hughes; Dan I. Andersson; Måns Ehrenberg; Stanley Maloy; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tufA; tufB; EF-Tu; ppGpp; Stringent response; RNase E; RNA turnover; Post-transcriptional regulation; rpoB; rpoS; Growth in stationary phase; Biology with specialization in Microbiology; Biologi med inriktning mot mikrobiologi; Mikrobiologi; Microbiology; Molekylär genetik; Molecular Genetics; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Abstract : 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. READ MORE
