  1. 1. 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

  3. 2. Abundance of root nodules on common bean, Phaseolus vulgaris : a comparison between Swedish fields with and without a recent history of common bean cultivation

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Soil and Environment

    Författare :Christina Hultman; [2018]
    Nyckelord :sustainability; protein-source; legume-based food; nitrogen fixation; root nodules;

    Sammanfattning : Legumes such as common bean, Phaseolus vulgaris L. are climate-smart protein sources which can be part of sustainable agriculture and eating habits to increase the resilience in our food system. LÄS MER

  4. 3. Development of PCR primers for community studies of bacterial hydrogenases in environmental samples

    Magister-uppsats, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

    Författare :Ernest Ndobe Ndobe; [2013]
    Nyckelord :uptake hydrogenase; bacterial community; biological nitrogen fixation; symbiosis;

    Sammanfattning : Soil microorganisms interact with plants in ways that affect nutrient availability, hormonal regulation and often lead to improved plant growth. In the N2-fixing root nodule symbiosis between legume plants and bacteria generally called rhizobia the plant gains access to atmospheric nitrogen. LÄS MER

  5. 4. Bacterial communities associated with roots of narrow-leafed lupin (Lupinus angustifolius L.) : diversity in relation to soil origin and effects on plant growth

    Master-uppsats, SLU/Dept. of Plant Biology and Forest Genetics (until 131231)

    Författare :Fang Chen; [2013]
    Nyckelord :lupin; Bradyrhizobium; symbiosis;

    Sammanfattning : Bacteria play several important ecological functions in soil and in relation to plants. Legumes, such as the recently introduced grain legume narrow-leafed lupin (Lupinus angustifolius L.), develop N2-fixing root nodules in response to infection by soil bacteria generally called rhizobia but can also interact with other soil bacteria.

  7. 5. Förekomsten av rotknölsbildande bakterier för Brun böna (Phaseolus vulgaris L.) och Blå lupin (Lupinus angustifolius L.) i olika jordar

    Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Christina Fröberg; [2013]
    Nyckelord :Rotknölsbildande bakterier; Brun böna Phaseolus vulgaris L. ; Blå lupin Lupinus angustifolius L. ; Försöksodling; Root nodule bacteria; Brown bean Phaseolus vulgaris L. ; Blue lupin Lupinus angustifolius L. ; Trial cultivation;

    Sammanfattning : Kvävgas kan inte tas upp direkt av växter men genom biologisk kvävefixering kan vissa symbiosbildande bakterier omvandla kvävgas till ammonium. Med bakteriens hjälp kan en växt tillgodogöra sig ammonium och på så sätt bilda protein. LÄS MER
