  2. 1. Light-regulated Development in Arabidopsis

    Author : Dongqing Xu; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; photomorphogenesis;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 3. TERMINAL FLOWER2, the Arabidopsis HETEROCHROMATIN PROTEIN1 Homolog, and its Involvement in Plant Development

    Author : Katarina Landberg; Annika Sundås Larsson; Peter Engström; Ove Nilsson; Uppsala universitet; []
    Keywords : Biology; Arabidopsis; HETEROCHROMATIN PROTEIN1; flowering; meristem; auxin; Biologi;

    Abstract : This thesis describes the characterization of the Arabidopsis thaliana mutant terminal flower2 (tfl2), the cloning of the corresponding gene, and the analysis of TFL2 function in plant development. The tfl2 mutant is pleiotropic, exhibiting early floral induction in both long and short day conditions, a terminating inflorescence and dwarfing. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. B-box Proteins in Light-regulated Development in Arabidopsis

    Author : Sourav Datta; Göteborgs universitet; []
    Keywords : light signaling; Arabidopsis;

    Abstract : 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. READ MORE
