  2. 1. Genomics of Arbuscular Mycorrhizal Fungi : Expanding knowledge, one assembly at a time

    Author : Merce Montoliu-Nerin; Anna Rosling; Hanna Johannesson; Nicolas Corradi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; genomics; arbuscular mycorrhizal fungi; phylogenomics; DNA; evolution; Bioinformatics; Bioinformatik; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : Most life forms that inhabit Earth today are still unknown or are difficult to study. Accessing their DNA can give us information of their biology, ecology, and evolution, even when unculturable. The research here presented focused on method development for genomic research of non-model organisms. READ MORE

  4. 2. Symbiosis in Arbuscular Mycorrhizal Fungi : Unearthing genomic signatures

    Author : Shadi Eshghi Sahraei; Anna Rosling; Vasilis Kokkoris; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; arbuscular mycorrhizal fungi; mutualistic symbiosis; soil microeukaryotic communities; phylogenomics; single spore assembly; gene family evolution; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Arbuscular mycorrhizal (AM) fungi have been on earth since 470 million years ago. AM fungi form mutualistic symbiosis with most terrestrial plants and thus, are thought to have played important roles in land colonization together with plants. READ MORE

  5. 3. Nutrient balance and salinity stress in arbuscular mycorrhizal fungi

    Author : Edith Hammer; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Inoculum; Glomalin; Fatty acids; Osmolyte; Organic matter; K; Na; Salinity; Symbiotic exchange; Phosphorus P; Carbon C; PIXE; Arbuscular mycorrhizal fungi; Rhizobium;

    Abstract : Earth’s primary production depends to a considerable extent on the mycorrhizal symbiosis, since mycorrhizal fungi supply their host plant with important mineral nutrients. I examined the influence of different nutrient regimes on the fungal partner in the arbuscular mycorrhizal symbiosis. READ MORE

  6. 4. Bacterial Activity and Community Composition in the Rhizosphere. Influence of plant species, root age, nitrogen addition and mycorrhizal status

    Author : Katarina Söderberg; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; CLPP; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi; Biolog; PLFA; mycorrhizal status; nitrogen addition; along roots; plant species; root age; thymidine and leucine incorporation; bacterial composition; Rhizosphere; bacterial activity;

    Abstract : Microbial activity in soil is generally assumed to be limited by carbon availability. The soil closest to roots, the rhizosphere, is therefore a zone of high microbial activity due to carbon containing substances released by the root. In this work short-term effects in the rhizosphere have been the subject of investigation. READ MORE

  7. 5. Colonization processes of soil fauna and mycorrhizal fungi

    Author : Dagmar Gormsen; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Animal ecology; abandonment; land use; ectomycorrhiza; arbuscular mycorrhiza; lumbricid earthworms; Acari; soil fauna; collembola; Djurekologi; Microbiology; bacteriology; virology; mycology; Mikrobiologi; bakteriologi; virologi; mykologi;

    Abstract : Colonization consists of two parts, a dispersal phase followed by establishment and reproduction at a new site. Dispersal behaviour influences survival and the access to resources and mates of individuals and is thus closely linked to an organism's fitness. READ MORE
