  1. 1. Peroxiredoxins in Redox Signaling and Aging

    Författare :Friederike Roger; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Aging; Peroxiredoxin; Redox Signaling; Caloric restriction; light sensing;

    Sammanfattning : Peroxiredoxins have emerged as conserved modulators of the rate of aging in yeast and multicellular organisms and play a role in lifespan extension through the anti-aging intervention caloric restriction. Yet, it is not clear through what mechanism peroxiredoxins extend lifespan. LÄS MER

  3. 2. B-box Proteins in Light-regulated Development in Arabidopsis

    Författare :Sourav Datta; Göteborgs universitet; []
    Nyckelord :light signaling; Arabidopsis;

    Sammanfattning : COP1 and HY5 are two key regulators of light signaling in plants. Proteins interacting with either could therefore be important regulators of light-dependent development. Previous yeast two-hybrid screens, using COP1 or HY5 as bait, identified several putative regulators of light signaling. LÄS MER

  4. 3. Shedding Light on Shade- and Dark-Induced Leaf Senescence

    Författare :Bastiaan Brouwer; Per Gardeström; Karin Krupinska; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; darkness; light; photosynthesis; phytochrome; shade; senescence;

    Sammanfattning : Leaf senescence is the final stage of leaf development, during which the leaf relocates most of itsvaluable nutrients to developing or storing parts of the plant. As this process progresses, leaves losetheir green color and their capacity to perform photosynthesis. LÄS MER

  5. 4. Epigenetic Regulation of Light and Hormonal Signaling in Arabidopsis thaliana

    Författare :Kristina Rizzardi; Annika Sundås-Larsson; Katarina Landberg; Johan Memelink; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TERMINAL FLOWER2; auxin; jasmonate; epigenetics; photomorphogenesis; Plant physiology; Växtfysiologi; Biologi med inriktning mot fysiologisk botanik; Biology with specialization in Physiological Botany;

    Sammanfattning : Plants are stationary and need to adapt to the environment they live in. Integration of environmental cues, such as changes in light and temperature, can occur either directly or through the action of hormones. Hormone and light signaling leads to rapid changes in gene expression, and eventually changes in protein levels. LÄS MER

  7. 5. Light-regulated Development in Arabidopsis

    Författare :Dongqing Xu; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; photomorphogenesis;

    Sammanfattning : Many external and internal factors affect multiple developmental processes in plants. Light is one of the essential factors that regulates various aspects of plant growth and development throughout their life cycle. LÄS MER
