  2. 1. Calreticulins- Calcium-Binding Proteins with Functional Diversity and Evolutionary Duality

    Author : Staffan Persson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant biochemistry; plant; isoforms; evolution; diversity; differential regulation; chaperone; calnexin; calmegin; calcium; Arabidopsis; calreticulin; Växtbiokemi;

    Abstract : Calreticulin is a multifunctional protein mainly localized in the endoplasmic reticulum in eukaryotic organisms, except yeasts. The protein comprises three distinct regions: the N-terminal N domain, the C-terminal C domain, and the central P domain, reflecting the functional diversity of calreticulin. READ MORE

  4. 2. Functional studies of plant hexokinases and development of genetic methods in the moss Physcomitrella patens

    Author : Mikael Ulfstedt; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : In the field of biology, model systems are frequently used for practical reasons. Model organisms possess several features that make them easy to work with in a laboratory setting. In addition they usually have a host of established genetic tools that have been developed by the research community. READ MORE

  5. 3. The role of vegetation dynamics in the control of atmospheric CO2 content

    Author : Stephen Sitch; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atmospheric CO2 content; climate change; plant functional types; terrestrial biosphere model; DGVM; vegetation dynamics; land use; land cover change; Plant ecology; Växtekologi;

    Abstract : This thesis contains a description of the Lund-Potsdam-Jena Dynamic Global Vegetation Model (LPJ-DGVM) and its application to infer the role of vegetation dynamics on atmospheric CO2 content at different time-scales. The model combines vegetation dynamics and biogeochemistry in a modular framework. READ MORE

  6. 4. Studies on Cytotoxic and Neutrophil Challenging Polypeptides and Cardiac Glycosides of Plant Origin

    Author : Senia Johansson; Tore Mellstrand; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutical chemistry; cytotoxic; neutrophil; polypeptides; Phoradendron tomentosum; Digitalis purpurea; plant; mistletoe; MS MS; Edman degradation; breast cancer; macrocyclic peptides; multidrug resistance protein; primary structures; phoratoxin; isolation; digitoxin; cardiac lycoside; structure-activity; Farmaceutisk kemi; Pharmaceutical chemistry; Farmaceutisk kemi; Pharmacognosy; farmakognosi;

    Abstract : This thesis examines the isolation and characterisation (biological and chemical) of polypeptides from plants. A fractionation protocol was developed and applied on 100 plant materials with the aim of isolating highly purified polypeptide fractions from small amounts of plant materials. READ MORE

  7. 5. Small remnant habitats : Important structures in fragmented landscapes

    Author : Jessica Lindgren; Sara Cousins; Regina Lindborg; Adam Kimberley; Ove Eriksson; Hans Henrik Bruun; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Alpha-diversity; Beta-diversity; Biological pest control; Canopy cover; Connectivity; Ecosystem function; Fleshy fruits; Forest edge; Forest management; Forest specialist species; Fragmentation; Functional diversity; Gamma-diversity; Grassland specialist species; Green infrastructure; Habitat amount hypothesis; Island biogeography; Midfield islets; Plant diversity; Plant-pollinator interaction; Pollination; Remnant habitat; Seed predation; Small habitats; Species richness; Structural heterogeneity; Physical Geography; naturgeografi;

    Abstract : The world-wide intensification of agriculture has led to a decline in species richness due to land use change, isolation, and fragmentation of natural and semi-natural habitats in agricultural and forestry landscapes. As a consequence, there is a current landscape management focus on the importance of green infrastructure to mitigate biodiversity decline and preserve ecosystem functions e. READ MORE
