  1. 1. Plant aquaporins

    Författare :Ingela Johansson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; water deficit; calcium; plasma membrane; Plant biochemistry; channel; phosphorylation; Växtbiokemi;

    Sammanfattning : Aquaporins are integral membrane proteins that specifically transports water. In plants, aquaporins have been identified in the plasma membrane and in the vacuolar membrane. LÄS MER

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

    Författare :Mikael Johansson; Maria E. Eriksson; Paul Devlin; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL 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

  3. 3. 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 :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; 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

  4. 4. Characterization of auxiliary membrane proteins in the chloroplast of Arabidopsis thaliana

    Författare :Lotta von Sydow; Christiane Funk; Wolfgang Schröder; Thomas Pfannschmidt; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; Arabidopsis; chaperone; chloroplast; Cytochrome b559; FtsH; membrane proteins; photosynthesis; Photosystem II; protease; PsbY.; Arabidopsis; chaperone; Cytochrome b559; fotosyntes; fotosystem II; FtsH; kloroplast; membranprotein; proteas; PsbY.; biokemi; Biochemistry;

    Sammanfattning : In nature, sessile plants have to adapt to their environment and to the never ending changes they are exposed to. They do so mainly by proteomic and metabolomic changes. In all cells, there are complex networks of auxiliary proteins that are responsible for quality control of all the cell's proteins. LÄS MER

  5. 5. Calcium transporting ATPases in plant cells

    Författare :Malin Olbe; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Triticum aestivum; calcium; Brij 58; calmodulin; Ca2 signalling; inside-out; endoplasmic reticulum; plant; plasma membrane; proteolysis; P-type ATPase; spinach; Spinacea oleracea; trypsin; two-phase; wheat.; Plant biochemistry; Växtbiokemi;

    Sammanfattning : Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes. LÄS MER
