  1. 1. Epigenetic Regulation of Light and Hormonal Signaling in Arabidopsis thaliana

    Författare :Kristina Rizzardi; Annika Sundås-Larsson; Katarina Landberg; Johan Memelink; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

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

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

    Sammanfattning : 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. LÄS MER

  3. 3. Spatial Models of Gene Patterns in Plants

    Författare :André Larsson; Institutionen för astronomi och teoretisk fysik; []
    Nyckelord :computational morphodynamics; gene regulation; spatial models; plants; development; auxin; meristem; Fysicumarkivet A:2017:Larsson;

    Sammanfattning : The growth and development of plants exhibits a striking symmetry, visible in the regular arrangement of leaves and flowers. Plant development is carefully controlled at the molecular level by gene regulatory networks, and the symmetry of plants can be observed also in the molecular patterns of gene expression. LÄS MER

  4. 4. Cell-to-Cell Signalling in Arabidopsis Root Development

    Författare :Christina Joy Roberts; Annelie Carlsbecker; Dolf Weijers; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; HD-ZIP III; miRNA; plasmodesmata; auxin; ROS; xylem; Biologi med inriktning mot fysiologisk botanik; Biology with specialization in Physiological Botany;

    Sammanfattning : Development in multicellular organisms requires a strict balance between cell division and differentiation. The simple architecture of the Arabidopsis thaliana root makes it an ideal model for studying molecular mechanisms controlling both the transition from cell division to cell differentiation and cell fate determination.
