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

    University dissertation from Umeå : Umeå Universitet, Institutionen för fysiologisk botanik

    Author : Mikael Johansson; Maria E. Eriksson; Paul Devlin; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; circadian clock; arabidopsis; populus; NATURAL SCIENCES Biology Cell and molecular biology Molecular biology; NATURVETENSKAP Biologi Cell- och molekylärbiologi Molekylärbiologi; TECHNOLOGY Bioengineering Plant biotechnology; TEKNIKVETENSKAP Bioteknik Växtbioteknik; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; molekylärbiologi; Molecular Biology;

    Abstract : 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. READ MORE

    Abstract : ABSTRACTThe xyloglucan endo-transglycosylase/hydrolase (XTH) genes are found in all vascular and some nonvascular plants. The XTH genes encode proteins which comprise a subfamily of glycoside hydrolase (GH) family 16 in the Carbohydrate-Active enZYmes (CAZY) classification. READ MORE

  4. 4. The plant respiratory chain: Redox responses and catalytic definition of alternative pathways

    University dissertation from Lund University Department of Cell and Organism Biology Sölvegatan 35B SE-223 62 Lund

    Author : Daniela Geisler; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; enzymology; Proteins; Kärlväxters fysiologi; Physiology of vascular plants; Växtekologi; Plant ecology; Växtbiokemi; Plant biochemistry; respiratory chain; plant mitochondria; nitrogen; NADPH dehydrogenase; NADH dehydrogenase; alternative oxidase; calcium; Proteiner; enzymologi; Bioenergetics; Bioenergetik; Lipids; steroids; membranes; Lipider; steroider; mebran;

    Abstract : The respiratory chain of plants contains both proton-pumping enzymes that conserve energy and non-proton-pumping alternative enzymes that bypass the sites of energy conservation. In addition to the proton-pumping complex I, plant mitochondria contain alternative type II NAD(P)H dehydrogenases, which allow oxidation of NADH and NADPH from the matrix and the cytosol. READ MORE

  5. 5. Specificity in natural and artificial cyanobacterial symbioses

    University dissertation from Stockholm : Department of Botany, Stockholm University

    Author : Malin Nilsson; Kristina Lindström; ; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; växtfysiologi; Plant Physiology;

    Abstract : Cyanobacteria, primarily of the genus Nostoc, form symbioses with a wide variety of plants. The diversity of cyanobacterial strains in these symbioses, and the specificity of interaction, vary greatly. A high diversity at the strain level has been suggested for bryophytes and cycads, whereas a low diversity is found in lichens. READ MORE
