  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.

  3. 2. A molecular network mediating adventitious root initiation in Arabidopsis thaliana

    Författare :Abdellah Lakehal; Catherine Bellini; Malcolm Bennett; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adventitious rooting; auxin; jasmonate; cytokinin; phytohormone perception and signalling; vegetative propagation;

    Sammanfattning : To adapt to the ever-changing rhizosphere conditions, land plants evolved a sophisticated root system. The genetic determinants of the root system establishment have been the targets of natural selection, resulting in a very complex but robust molecular networks and circuits. LÄS MER

  4. 3. Cytokinins as regulators of adventitious root formation

    Författare :Marie Bollmark; Stockholms universitet; []

  5. 4. Auxin dynamics during adventitious root formation in pea (Pisum sativum L.) cuttings

    Författare :Ann-Caroline Nordström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ärtväxter;

    Sammanfattning : The regulatory function of the auxins indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) inadventitious root formation was studied in cuttings of pea (Pisum sativum L.). These auxins, aswell as the conjugate of IAA with aspartic acid (lAAsp), were identified as naturally occurringconstituents in both seedlings and cuttings. LÄS MER

  7. 5. Understanding of molecular mechanisms and improving of adventitous root formation in apple

    Författare :Anders Smolka; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Adventitious root formation is essential for vegetative propagation, which is the main method for propagation of many horticultural crops, especially woody species. For propagation of apple rootstocks, adventitious root formation is often a limiting step. LÄS MER
