  1. 1. How low levels of glucose and tryptophan may signal changes in development and symbiotic potential of ectomycorrhizal fungus Laccaria bicolor

    University essay from Umeå universitet/Institutionen för fysiologisk botanik

    Author : Alexandra Goetsch; [2020]
    Keywords : ;

    Abstract : Symbiosis between tree species and ectomycorrhizal fungi is a fundamental relationship that promotes the overall health of boreal and temperate forests. Nutrient exchange between the two organisms is mutualistic in nature however establishment of this relationship is still not fully understood. READ MORE

  3. 2. Alternative oxidase respiration in the mycorrhizal fungus Laccaria bicolor

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Hilda Mikaelsson; [2019]
    Keywords : L. bicolor; mycel; ektomykorrhiza; cellandning; AOX; alternativt oxidas; cytokromoxidas; cyanid; mycelium; ectomychorriza; respiration; alternative oxidase; cytochrome oxidase; salicylhydroxamic acid; n-propyl gallate; cyanide;

    Abstract : The temperature on Earth is rising, and one of the main drivers is anthropogen-ic greenhouse gases such as carbon dioxide (CO2). The world’s forests act as carbon sinks, binding carbon into their biomass. The net carbon assimilation is determined by the uptake and release of CO2 through the processes of photo-synthesis and respiration. READ MORE

  4. 3. Morphological characterisation of sorghum (Sorghum bicolor) diversity in Burundi

    University essay from SLU/Swedish Biodiversity Centre

    Author : Espérance Habindavyi; [2009]
    Keywords : Burundi; landraces; morphological traits; variability; Sorghum bicolor;

    Abstract : Sorghum (Sorghum bicolor (L.)Moench), is a cereal crop close to maize and sugar cane. The crop originated in the Northeast part of Africa and has been an important crop in many dry areas of tropical countries. Sorghum is used for beverage and porridge for many people of Africa.

  5. 4. Effects of shade and humus fertility on boreal forest tree seedling growth, competition and mycorrhizal colonisation

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Helena Dehlin; [2001]
    Keywords : far-red light; adaptive plasticity; mineral-nutrition; birch seedlings; Scots pine seedlings; spruce seedlings; regeneration dynamics; mycorrhizal symbioses; soil fertility; interspecific interactions;

    Abstract : In boreal forest ecosystems, growth of tree seedlings is limited by resources both aboveground (through shading) and belowground (through nutrient limitation), and the ability to tolerate or avoid these conditions is important in determining the relative performance of different tree species. Two of the means to compete for these resources, are through increasing stem-elongation to escape shading by neighbours (shade avoidance), and through mycorrhizal symbiosis that may increase the nutrient- and water up-take.
