  1. 1. The evolutionary origins of phagocytosis in microbial populations

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Alfred Leimar; [2022]
    Nyckelord :Theoretical ecology; phagocytosis; predation; adaptive dynamics;

    Sammanfattning : The emergence of the eukaryotic cell was one of the key events that paved the path to the vast variety of complex life visible all around us. A pivotal event in the process of eukaryogenesis was an endosymbiosis of two prokaryotic cells which in time resulted in the mitochondria. LÄS MER

  3. 2. The metagenomes of root nodules in actinorhizal plants : A bioinformatic study of endophytic bacterial communities

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Ellen Fasth; [2021]
    Nyckelord :Actinorhizal plants; Frankia; endosymbiosis; root nodules; metagenomes; bioinformatics;

    Sammanfattning : Actinorhizal plants are in symbiosis with the nitrogen-fixating soil bacterium Frankia, which forms nodules in the plant root. However, several studies also report other endophytic bacteria appearing in the nodules, but their function and interaction with the host plant or Frankia is not yet understood. LÄS MER

  4. 3. Does arbuscular mycorrhiza symbiosis increase the capacity or the efficiency of the photosynthetic apparatus in the model legume Medicago truncatula?

    Master-uppsats, Molekylär genetik

    Författare :Ateeq ur Rehman; [2010]
    Nyckelord :Medicago truncatula; Arbuscular mycorrhiza symbiosis; Photosynthesis; Chlorophyll fluorescence; Oxygen evolution; Lhcb1 and Lhcb2 proteins content; phosphor uptake; Reproductive fitness;

    Sammanfattning : The Arbuscular mycorrhiza (AM) is an endosymbiont of higher plant roots. Most land plants and cultivated crops are concerned to AM symbiosis. This endosymbiosis is based on the mutual exchange of nutrients between plant and fungus. Therefore, AM symbiosis leads to an increased demand for photosynthetic products. LÄS MER
