  1. 1. The diversity of fungi in coniferous forests and mixed forests

    Master-uppsats, Karlstads universitet

    Författare :Ida Asplund; [2023]
    Nyckelord :Forest type; coniferous forest; mixed forest; fungi; fungal diversity; mycorrhiza; saprotrothic fungi; parasites; parasitic fungi; Skogstyp; barrskog; blandskog; svampar; svampdiversitet; svampmångfald; mykorrhiza; saprotrofiska svampar; parasiter; parasitiska svampar;

    Sammanfattning : The fungal domain has one of the highest biodiversities among eukaryotes and species within the domain fill important ecological roles, such as mutualistic mycorrhiza, decomposers, parasites and pathogens. The development of forest ecosystems and their related processes has not only been linked to fungal diversity but the composition and abundance of fungi benefits the abundance and diversity of other species as well.

  3. 2. Production of gangliosidebiosynthetic membrane enzymes for biochemical and functionalstudies : Expression, purification and crystallizationoptimization of Thermococcus onnurineus Dolicho l-phosphate mannose synthase, Homosapiens and Branchiostoma floridae Glucosylceramide synthase

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Ellinor Lindholm; [2018]
    Nyckelord :glycoconjugates; glycolipids; integral membrane proteins; gangliosides; glucosylceramide synthase; dolicholphosphate mannose synthase; cancer; neuroblastoma; congenital disorders of glycosylation; glykokonjukat; glykolipider; membranprotein; gangliosider; glukosylceramidsyntas; dolicholfosfat mannossyntas; cancer; neuroblastom; medfdd glykosyleringssjukdom;

    Sammanfattning : Glycolipids play important roles in the biology of prokaryotes and eukaryotes, including humans, and although theyare found on the cell-membrane surface of all eukaryotic cells, not much is known about their biosynthesis. The aim ofthis project was to characterize two enzymes: glucosylceramide synthase (GCS) which is involved in the biosynthesisof glycolipids such as gangliosides that are abundant in the membranes of nerve cells; and dolicholphosphate mannosesynthase (DPMS), involved in the synthesis precursor for protein glycosylation.

  4. 3. Towards a function for an Arabidopsis protein involved in sucrose dynamics

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Jonas Skytte af Sätra; [2013]
    Nyckelord :Sucrose; MAPK; signalling; soluble heteroglycans;

    Sammanfattning : System based models of plants rely on descriptions and assigned functions of genes, and currently 50% of the genes in Arabidopsis thaliana has either no assigned function or a function based on homology only. Mitogen activated protein kinases (MAPK's) are key players in cell signalling and are conserved among eukaryotes, though their targets are highly diverse. LÄS MER

  5. 4. Undersökning av Ammoniumoxiderande Arkéer i reningsverks slam

    Kandidat-uppsats, Akademin för hållbar samhälls- och teknikutveckling

    Författare :Nuha Moses Matti; [2010]
    Nyckelord :;

    Sammanfattning : Livsformerna på jorden delas systematiskt in i de tre domänerna bakterier, arkéer och eukaryoter. Arkéer är de mikroorganismer som lever i extrema miljöer såsom hetvattenkällor, sjöar med hög salthalt och i miljöer med extrema pH-värden. LÄS MER

  7. 5. Expression av PSI-N från Arabidopsis thaliana i E : coli

    Kandidat-uppsats, Sektionen för lärarutbildning (LUT)

    Författare :Louise Ek; Marielle Halltorp; [2008]
    Nyckelord :Photosystem; Expression; PSI-N;

    Sammanfattning : PSI-N is one of the subunits in eukaryotic Photosystem I (PSI) and is located on the lumenal side of the thylakoid membrane. It is known to interact in the electron transport chain between plastocyanin and PSI, but the mechanism behind the interaction is still unclear. LÄS MER
