  1. 1. Modelling the development of phyllotactic patterns at the shoot apical meristem of Arabidopsis thaliana

    Författare :Patrik Sahlin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; systems biology; plant stem cells; computational morphodynamics; shoot apical meristem; Arabidopsis; cell division; Fysicumarkivet A:2010:Sahlin;

    Sammanfattning : The study of phyllotactic patterns have a long history, but the bulk of our detailed understanding of developmental processes in plants comes from research conducted in the last thirty or forty years. New modern techniques have made it possible to study plants in ways that previously was not possible. LÄS MER

  3. 2. Meristem Maintenance in Arabidopsis thaliana

    Författare :Alessia Para; Annika Sundås Larsson; Jan Traas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Life sciences and physical sciences; Arabidopsis thaliana; development; shoot apical meristem; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : The shoot apical meristem (SAM) is the structure that shapes the aerial architecture of the plant, by producing lateral organs throughout development. In the model plant Arabidopsis thaliana, the SAM is always identifiable as a characteristic dome, whether it is found in the centre of a rosette of leaves or at the tip of an inflorescence. LÄS MER

  4. 3. Analysis of Two Transcriptional Regulators that Affect Meristem Function : Arabidopsis thaliana TERMINAL FLOWER2 and Picea abies APETELA2

    Författare :Lars Nilsson; Annika Sundås Larsson; Peter Engström; Thomas Laux; Uppsala universitet; []
    Nyckelord :Developmental biology; Arabidopsis thaliana; Picea abies; gene regulation; development; meristem; Utvecklingsbiologi;

    Sammanfattning : The aerial plant body is derived from undifferentiated cells in the shoot apical meristem that in Arabidopsis thaliana is active throughout the plant life cycle. Upon transition to flowering the activity of the meristem is altered and the meristem starts to produce secondary inflorescences and floral meristems instead of leaves. LÄS MER

  5. 4. Life History Strategies in Linnaea borealis

    Författare :Mikael Niva; Brita M. Svensson; P. Staffan Karlsson; Ørjan Totland; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; Linnaea borealis; apex removal; apical dominance; clonal plant; hand pollination; matrix modelling; plant foraging; resorption efficiency; resorption proficiency; resource heterogeneity; shoot dynamics; Biologi; Biology; Biologi; ekologisk botanik; Ecological Botany;

    Sammanfattning : About 70% of the plant species in the temperate zone are characterised by clonal growth, clonal species are also in majority in the Arctic and Subarctic where they affect the structure and composition of the vegetation. It is therefore of great importance to increase our knowledge about clonal plants and their growth and life histories. LÄS MER

  7. 5. Evolution in multicellular mitotic lineages

    Författare :Mario Pineda; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mosaic; modular organisms; spatial interactions; individualtiy; somatic embryogensis; ontogeny; clonality; meristem; chimera; Ecology; Ekologi;

    Sammanfattning : Many animals, and all plants and fungi, produce vegetative offspring, i.e. descendant individuals that originate from mitotic, rather than meiotic, cell lineages. Many animals, and all plants and fungi, produce vegetative offspring, i. LÄS MER
