    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Plant Physiology; växtfysiologi;

    Sammanfattning : The primary objective of this thesis was to investigate the sterol metabolism of two pathogenic oomycetes, specifically the processes of sterol synthesis and sterol acquisition in the fish pathogen Saprolegnia parasitica (Saprolegniales) and the plant pathogen Phytophthora infestans (Peronosporales). Furthermore, the effects of steroidal glycoalkaloids from Solanaceous plants, on P. LÄS MER

  3. 22. The Structure-Function Relationship and Evolution of Deoxyribonucleoside Kinases

    Författare :Zeeshan Mutahir; Molekylär cellbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The synthesis of deoxyribonucleoside triphosphates (dNTPs), building blocks of DNA, can be achieved by two different pathways in the cell. One is called de novo synthesis and the other is known as salvage pathway. The de novo pathway involves synthesis of dNTPs by utilizing basic molecules like sugars, amino acids, CO2, NH3, etc. LÄS MER

  4. 23. A tale of two blights

    Sammanfattning : Potato is the third most important food crop for human consumption. However, the production is plagued by several pests and pathogens causing yield reducing diseases. Estimations indicate that 17% of the global potato yield is lost due to pests and pathogens. LÄS MER

  5. 24. Towards Understanding of Selectivity & Enantioconvergence of an Epoxide Hydrolase

    Författare :Åsa Janfalk Carlsson; Mikael Widersten; Uwe T. Bornscheuer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Epoxide hydrolase; Epoxide; Enantioselectivity; Regioselectivity; Enantioconvergence; Crystal structures; Biocatalysis; Immobilization; Transient kinetics; CASTing; Directed evolution; Biokemi; Biochemistry;

    Sammanfattning : Epoxide hydrolase I from Solanum tuberosum (StEH1) and isolated variants thereof has been studied for mapping structure-function relationships with the ultimate goal of being able to in silico predict modifications needed for a certain activity or selectivity. To solve this, directed evoultion using CASTing and an ISM approach was applied to improve selectivity towards either of the enantiomeric product diols from (2,3-epoxypropyl)benzene (1). LÄS MER

  7. 25. Banana xanthomonas wilt and potato bacterial wilt in Rwanda : biology, risk factors and farmers’ awareness

    Författare :Florence Uwamahoro; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Banana (Musa spp.) and potato (Solanum tuberosum) are important food and cash crops worldwide as they contribute to food security and income generation for farmers. Despite their importance, banana and potato do not reach their potential production due to a number of limitations, including pests and diseases. LÄS MER
