  1. 11. Ecotoxicological studies on giant clams (Tridacnidae) : Environmental problems and future concerns

    Författare :Eva Blidberg; Michael Tedengren; David Klumpp; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; giant clam; larval; physiology; zooxanthellae; Biology; Biologi;

    Sammanfattning : Giant clams (Tridacnidae; Bivalvia) are described as important framework builders on coral reefs in the Indo-Pacific region. They are phototrophic as they are associated with primary producing zooxanthellae. Populations are low due to over-exploitation and most species are now endangered in many areas. LÄS MER

  3. 12. Structural and functional studies of the ATP-dependent Clp proteases in cyanobacteria

    Författare :Frida Ståhlberg; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtmolekylärbiologi; Clp Proteaser; Synechococcus elongatus;

    Sammanfattning : Proteins are essential in all living organisms and they are involved in a myriad of biological functions. It is vital for cells to have efficient surveillance and quality control systems that ensure damaged proteins are either repaired to their functional state or quickly removed by degradation. LÄS MER

  4. 13. Biochemical studies of the essential Clp protease in cyanobacteria and its associated adaptor proteins

    Författare :Anders Tryggvesson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Clp-protease; Cyanaobacteria; adaptor proteins;

    Sammanfattning : Proteins are an essential part of all organisms and are involved in many cellular processes. To regulate the function of proteins and facilitate their removal when damaged or otherwise compromised, sophisticated control systems have evolved that include molecular chaperones and proteases.

  5. 14. FtsH metalloproteases and their pseudo-proteases in the chloroplast envelope of Arabidopsis thaliana

    Författare :Laxmi S. Mishra; Christiane Funk; Magnus Wolf-Watz; Catherine de Vitry; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Arabidopsis thaliana; AAA-ATPases; abscisic acid; chloroplast; drought; embryo-lethal; FtsH metalloprotease; intrinsic water-use efficiency WUEi ; leaf variegation; outdoor conditions; oxidative stress; plastid biogenesis; proteomics; protein import; root-associated bacterial communities seedlings; Biochemistry; biokemi; molekylärbiologi; Molecular Biology; biology; biologi;

    Sammanfattning : By cleaving peptide bonds, proteases either activate or degrade proteins and maintain protein quality control in response to various developmental stimuli and environmental factors. My work has focused on elucidating the role of the filamentation temperature sensitive protein H (FtsH) proteases. LÄS MER

  7. 15. Biological growth on rendered façades

    Författare :Sanne Johansson; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; temperature; render; radiation; photosynthesis; moulds; mosses; mortar; moisture; lichens; Imaging-PAM; humidity; heat capacity; heat; ETICS; algae; biological growth; calorimetry; desiccation tolerance;

    Sammanfattning : Biological organisms have an incredible ability to adapt to almost any environment and the humans activities on earth have created many new habitats for different kinds of organisms. For example can certain organisms grow on rocks and vertical cliffs, and when humans started building houses with mineral based façades, some organisms found that these were new habitats to live on.
