  2. 1. Effects of nitrogen deposition on the growth, metabolism and activity of ectomycorrhizal fungi

    Author : Magnus Ellström; MEMEG; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nitrogen deposition; Ectomycorrhizal fungi; Symbiosis; SOM modification; Carbon starvation; Metabolism; Nitrogen leakage; IR-spectroscopy; Mesh bags; Microarray; Axenic growth; Transcriptomics.;

    Abstract : Elevated nitrogen (N) deposition is an environmental problem that can affect plants and microorganisms, which are vital for the terrestrial N and carbon (C) cycles. This thesis has investigated the response of ectomycorrhizal fungi (EMF) to increased N deposition. READ MORE

  4. 2. Wastewater treatment and biomass generation by Nordic microalgae : growth in subarctic climate and microbial interactions

    Author : Lorenza Ferro; Christiane Funk; Francesco Gentili; Luísa Gouveia; Umeå universitet; []

  6. 4. Molecular interactions between quinoa, the biocontrol agent Trichoderma and the pathogen Peronospora variabilis

    Author : Oscar Miguel Rollano Penaloza; Molekylär cellbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chenopodium quinoa; Peronospora variabilis; Trichoderma harzianum; Molecular interactions; qRT-PCR; RNA-seq; Plant growth promotion; Chenopodium quinoa; Peronospora variabilis; Trichoderma harzianum; RNA-seq; qRT-PCR; molekylära interaktioner;

    Abstract : Plants have developed complex molecular mechanisms to recognize and respond to the different microorganisms present in their surroundings. The most studied response mechanisms are plant defense responses. These defense response mechanisms share many similar components with the plant response mechanisms to beneficial microbes. READ MORE

  7. 5. Quaternary structure and interaction approaches to allosteric regulation of class I ribonucleotide reductases

    Author : Mikael Crona; Britt-Marie Sjöberg; Mark Meuth; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ribonucleotide reductase; allosteric regulation; quaternary structure; subunit interactions; enzyme activity; SPR; GEMMA; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Abstract : Deoxyribonucleic acid (DNA) chains in which our genetic blueprint is stored are built from four DNA precursors by DNA polymerases. The enzyme ribonucleotide reductase (RNR) provides the only de novo synthesis pathway of deoxyribonucleotides from ribonucleotides and is essential for nearly all organisms. READ MORE
