  1. 1. System ecology of legumes mixes in ley production : impact on pollinating insects and further implications for production in northern Sweden

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Philippe Simon; [2023]
    Keywords : Ley production; Nitrogen fixation; Pollination ecology;

    Abstract : The population and diversity of pollinating insects in Europe are declining, partly due to lossof habitat. In agricultural landscapes, farming practices with more intensified land use haveincreased. In Swedish agricultural habitats, most ley production is dominated by grass and red clover (Trifolium pratense). READ MORE

  3. 2. Nodulation and biomass development of yellow and blue lucerne under pH stress

    University essay from SLU/Dept. of Crop Production Ecology

    Author : Katarina Boström; [2023]
    Keywords : lucerne; blue lucerne BL ; yellow lucerne YL ; E. meliloti; nodulation; pH;

    Abstract : Approximately 77% of global arable land use is devoted to forage cultivation, which is the basis for animal production and global food security. Therefore a sustainable and biologically diverse forage cultivation is needed. Feed for cattle needs to contain a good balance between fibre, energy and protein. READ MORE

  4. 3. Swedish red clover-associated Rhizobium leguminosarum bv. trifolii share high genetic similarity in the 16S gene but divergence in nod genes

    Author : Tua Lilja; [2023]
    Keywords : genetics; nitrogen fixation; sustainability; symbiosis; taxonomy;

    Abstract : Rhizobium leguminosarum biovar trifolii (Rlt) is a root-associated soil bacterium (rhizobia) capable of entering a symbiotic relationship with various species of clover (Trifolium sp.) and fix nitrogen within root nodules. READ MORE

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

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Ellen Fasth; [2021]
    Keywords : Actinorhizal plants; Frankia; endosymbiosis; root nodules; metagenomes; bioinformatics;

    Abstract : 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. READ MORE

    University essay from SLU/Dept. of Soil and Environment

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

    Abstract : 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. READ MORE
