  1. 1. Seagrass productivity from plant to system

    University dissertation from Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Diana Deyanova; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Seagrass; Chlorophyll a fluorescence; Ageing; Productivity; Seasonality; Stress response; växtfysiologi; Plant Physiology;

    Abstract : Seagrasses form one of the most productive habitats on earth and are recognized as very efficient carbon sinks. The levels and patterns of productivity within and across different seagrass systems vary widely due to natural or human-induced factors. READ MORE

  2. 2. 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; Lunds universitet.; Lund University.; [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 : Popular Abstract in Swedish Växternas respirationskedja innehåller protonpumpande enzymer, som konserverar energi i form av en protongradient, samt alternativa icke-protonpumpande enzymer. I det mitokondriella innermembranet finns ett protonpumpande NADH dehydrogenas, komplex I, och alternativa typ II NAD(P)H dehydrogenaser som kan oxidera NADH och NADPH från matrixen eller cytosolen.

  3. 3. The actinorhizal plant Datisca glomerata interpreting its symbiotic adaptations by omics-based comparisons with model and non-model organisms

    University dissertation from Stockholm University : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Author : Marco Salgado; Stockholms universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Root nodule symbiosis; nitrogen fixation; actinorhizal; Datisca glomer-ata; Frankia; nodule development; defensin; antimicrobial; carboxylate transporter; phylogenomics; transcriptomics; växtfysiologi; Plant Physiology;

    Abstract : Nitrogen is the element that most often limits plant growth and development. Common agricultural practices rely on the application of large quantities of industrially-produced nitrogen fertilizer, which poses a worldwide environmental threat. Sustainable agriculture encourages the use of biologically fixed nitrogen. READ MORE

  4. 4. 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; Umeå universitet.; [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

  5. 5. The light-harvesting antenna of higher plant photosystem I

    University dissertation from Umeå : Umeå universitet

    Author : Ulrika Ganeteg; Umeå universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; antisense; Arabidopsis thaliana; chlorophyll; fitness; LHC; photosynthesis; Växtfysiologi; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi;

    Abstract : During photosynthesis, two multi-protein complexes, photosystems (PS) I and II work in tandem to convert the light-energy absorbed by the light-harvesting antennae into chemical energy, which is subsequently used to assimilate atmospheric carbon dioxide into organic carbon compounds. This is the main nutritional basis for life on Earth. READ MORE
