  1. 11. AtZDP, a Plant 3' DNA Phosphatase, Involved in DNA Repair

    Författare :Isabel Valsecchi; Lars Rask; Per Jemth; Christer Larsson; Uppsala universitet; []
    Nyckelord :Molecular biology; AtZDP; plant long patch Base Excision Repair; DNA 3 phosphate blocking lesions; DNA repair; Molekylärbiologi;

    Sammanfattning : DNA bases can be modified by endogenous agents (e.g. oxidized by products of respiration and photosynthesis or methylated by gene silencing processes) as well as by environmental agents (e.g. LÄS MER

  3. 12. Long-lasting ecological legacies of reindeer on tundra vegetation

    Författare :Dagmar D. Egelkraut; Johan Olofsson; Bruce Forbes; Hans Tømmervik; René van der Wal; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Alternative stable state; Herbivory; Historical contingency; Nutrient cycling; Plant-herbivore interactions; Plant-soil feedbacks; Rangifer tarandus; Reindeer herding; Traditional land use; Tundra vegetation;

    Sammanfattning : Reindeer can have strong effects on the plant species composition and functioning of tundra ecosystems, and often promote a transition towards a graminoid-dominated vegetation type. As a result, they influence many ecological processes, such as nutrient dynamics, soil biotic composition and functioning, and carbon storage. LÄS MER

  4. 13. Regulatory Functions of Protein Phosphorylation in Plant Photosynthetic Membranes

    Författare :Rikard Fristedt; Alexander Vener; Thomas Pfannschmidt; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Oxygenic photosynthesis is the process in plants, algae and cyanobacteria which converts light energy from the sun into carbohydrates and at the same time produces oxygen from water. Both carbohydrates and oxygen are essential to sustain life on earth. LÄS MER

  5. 14. Plant responses after drainage and restoration in rich fens

    Författare :Kalle Mälson; Håkan Rydin; Sebastian Sundberg; Harri Vasander; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ecology; brown mosses; bryophytes; colonization; competition; dispersal limitation; liming; mire; peatland; rewetting; wetland restoration; Ekologi;

    Sammanfattning : Rich fens are an important, but threatened, habitat type in the boreal landscape. In this thesis I have examined responses of rich fen vascular plants and bryophytes after drainage and restoration.The effects of drainage on the rich fen flora were observed in a long time study and the responses were rapid and drastic.

  7. 15. A Strategic Perspective on Plants in Manufacturing Networks

    Författare :Andreas Feldmann; Jan Olhager; John Johansen; Linköpings universitet; []
    Nyckelord :Empirical research; manufacturing networks; performance; plant roles; site competences; strategy; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This dissertation addresses the topic of manufacturing network strategies, with a particular focus on the plant perspective. Research on manufacturing networks aims at contributing decision support on how to set up and how to coordinate factories that act in a global setting. LÄS MER
