  1. 1. Characterization of adventitious root formation in Populus species and Norway spruce

    Författare :Sanaria Alallaq; Catherine Bellini; Carmen Diaz-Sala; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adventitious root; Conifers; Picea abies; auxin; cytokinins; jasmonate; red light; Populus spp.; hybrid poplar; hybrid aspen; cambium; stem cuttings; P. tremula; Swedish Aspen SwAsp collection;

    Sammanfattning : Adventitious root (AR) formation is a form of post-embryonic development and is a key adaptive trait in plants. De novo adventitious root regeneration represents an elegant evolutionary innovation that allows many plant species to multiply through vegetative propagation; it is widely used in forestry and horticulture to multiply elite genotypes.

    Sammanfattning : The woody tissues serve to stabilise plants, store nutrients and translocate water and minerals. The formation of wood, or ’secondary xylem’, follows a well-defined developmental gradient which is initiated by cell division activity in the vascular cambium. LÄS MER

  4. 3. Molecular regulation of vascular cambium identity and activity

    Författare :Melis Kucukoglu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In plants, secondary development and wood formation originates from the cell divisions within the vascular meristem, where the vascular stem cells are located. This thesis work presents my results on the molecular regulation of vascular cambium stem cell identity and activity. LÄS MER
