  1. 1. The role of regeneration in plant niche differentiation and habitat specialization

    Författare :Dirk-Jan ten Brink; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; seed mass; seed size; drought; shade; seed germination; seed dormancy; seedling establishment; plant community ecology; assembly rules; habitat specialization; plant recruitment; Regeneration; niche differentiation; phylogenetic independent contrasts; plant traits; soil fertility; comparative ecology;

    Sammanfattning : To predict the effects of environmental change and nature management on the distribution of plant species, it is crucial to understand the mechanisms of plant niche differentiation and habitat specialization. The importance to habitat specialization of particular plant traits and requirement of the regenerative phase of the plants life has received scanty interest. LÄS MER

  3. 2. 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

  4. 3. 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
