    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoological Developmental Biology; zoologisk utvecklingsbiologi;

    Sammanfattning : Many cellular responses are regulated at the transcriptional level. Newly synthesized proteins and peptides rapidly exert their function at the time of expression, as a response to different environmental cues. LÄS MER

  3. 2. Analysis of sterol metabolism in the pathogenic oomycetes Saprolegnia parasitica and Phytophthora infestans

    Sammanfattning : The primary objective of this thesis was to investigate the sterol metabolism of two pathogenic oomycetes, specifically the processes of sterol synthesis and sterol acquisition in the fish pathogen Saprolegnia parasitica (Saprolegniales) and the plant pathogen Phytophthora infestans (Peronosporales). Furthermore, the effects of steroidal glycoalkaloids from Solanaceous plants, on P. LÄS MER

  4. 3. The actinorhizal symbiosis of the earliest divergent Frankia cluster

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant Physiology; växtfysiologi;

    Sammanfattning : In recent years, the need to reduce reliance on synthetic nitrogen fertilizer has led to extensive research on biological nitrogen fixation, especially on root nodule symbioses. My study focuses on actinorhizal symbioses, the symbiotic interactions between members of nitrogen-fixing soil actinobacteria from the genus Frankia and a diverse group of plants from eight families, collectively called actinorhizal plants.
