  1. 1. On the Ecology and Evolution of seed and Bud Dormancy

    Författare :Patric Nilsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bet-hedging; overcompensation; herbivory; plant compensatory growth; bud dormancy; endosperm; seed provisioning; Seed dormancy; parent-offspring conflicts; Ecology; Ekologi; Botany; Botanik;

    Sammanfattning : This thesis considers the ecological and evolutionary significance of seed and bud dormancy. First, I present theoretical support to the idea that seed dormancy may evolve as a strategy to reduce sib competition in temporally homogeneous environments. LÄS MER

  3. 2. Studies on regulatory networks governing virulence gene transcription in Staphylococcus aureus

    Författare :Erik Gustafsson; Högskolan i Skövde; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Naturvetenskap; Natural sciences;

    Sammanfattning : Staphylococcus aureus pathogenicity is dependent on the coordinated action of a number of virulence factors and the expression of these virulence factors is determined by several global regulators. The main regulator seems to be agr but there are several additional regulators (mostly sarA homologues) involved that mainly act downstream of agr. LÄS MER

  4. 3. Transcriptional profiling of human embryonic stem cells and their functional derivatives

    Författare :Jane Synnergren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transcription; differentiation; human embryonic stem cells; gene expression; Naturvetenskap;

    Sammanfattning : Human embryonic stem cells (hESCs) represent populations of pluripotent, undifferentiated cells with unlimited replication capacity, and with the ability to differentiate into any functional cell type in the human body. Based on these properties, hESCs and their derivatives provide unique model systems for basic research on embryonic development. LÄS MER
