  1. 11. Symbiotic and pathogenic factors in plant-microbe interaction: Structural basis of C-glycoside metabolism and lipoprotein transport in bacteria

    Författare :Valentina Furlanetto; Christina Divne; Mats Sandgren; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Plant-Bacteria Interaction; Symbiotic Communication; C-Glycosylated Compounds; Enzymatic Deglycosylation; Pathogenic Interactions; Lipoprotein Localization; Lol System; Biotechnology; Bioteknologi;

    Sammanfattning : The communication between plants and bacteria involves a complex chemical signaling network that mediates responses to various biotic and abiotic stresses, as well as establishing symbiotic relationships between different organisms.The first part of the thesis focuses on a mechanism for symbiotic communication between plants and bacteria and more specifically on how C-glycosylated aromatic polyketide compounds produced by plants can be used as a mechanism for plants to communicate with beneficial bacteria.

  3. 12. Molecular characterization of the interplay between DNA-PK and TRF2 in telomere protection

    Författare :Beatrice Toia; Francisca Lottersberger; Anita Öst; Grazia Daniela Raffa; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The genetic material of mammalian cells is organized as linear chromosomes inside their nucleus. In order to preserve genomic stability, mammalian cells have developed several mechanisms to detect and repair DNA lesions that can occasionally occur in the genome. LÄS MER

  4. 13. Phase-Contrast X-Ray Imaging of Complex Objects

    Författare :Ilian Häggmark; Hans Hertz; Anna Burvall; Henning Friis Poulsen; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Fysik; Physics; Biological and Biomedical Physics; Biologisk och biomedicinsk fysik;

    Sammanfattning : X-ray imaging is a group of techniques using electromagnetic radiation of high energy. The ability to quickly visualize internal structures in thick opaque objects has made it an indispensable tool in research, medicine, and industry. LÄS MER

  5. 14. Particle-Induced Phase Separation in Aqueous Solutions containing Colloidal Particles and Adsorbing Polymers

    Författare :Martin Olsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Polymer technology; biopolymers; Polymerteknik; theoretical calculations; particle-induced phase separation; phase behaviour; surfactant; colloidal particles; adsorbing polymer;

    Sammanfattning : The influence of added colloidal particles on the phase behaviour of a polymer solution was investigated. Binary, quasi-binary and mixed polymer solutions were used in the study, where at least one of the polymers had an affinity for the surfaces of the colloidal particles. LÄS MER

  7. 15. The circadian clock in annuals and perennials : coordination of Growth with Environmental Rhythms

    Författare :Mikael Johansson; Maria E. Eriksson; Paul Devlin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; circadian clock; arabidopsis; populus; Molecular biology; Molekylärbiologi; Plant biotechnology; Växtbioteknik; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Since the first signs of life on planet earth, organisms have had to adapt to the daily changes between light and dark, and high and low temperatures. This has led to the evolution of an endogenous time keeper, known as the circadian clock. LÄS MER
