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

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

    Abstract : 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. READ MORE

  4. 2. Genetic and Molecular Mechanisms Controlling Reactive Oxygen Species and Hormonal Signalling of Cell Death in Response to Environmental Stresses in Arabidopsis thaliana

    Author : Per Mühlenbock; Stanislaw Karpinski; Barbara Karpinska; Pierre Frendo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; Växtfysiologi;

    Abstract : In the present work the regulation of environmentally induced cell death and signaling of systemic acquired acclimation (SAA) in Arabidopsis thaliana is characterized. We used the lesion simulating disease1 (lsd1) mutant as a model system that is deregulated in light acclimation and programmed cell death (PCD). READ MORE

  5. 3. Functional analyses of growth and development in the liverwort Marchantia polymorpha

    Author : Anja Billhardt; D. Magnus Eklund; Marcel Quint; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Land plant evolution; Bryophytes; Marchantia polymorpha; Dormancy; Circadian clock;

    Abstract : Land plants developed from a freshwater charophycean algae about 500 million years ago. Today, they consist of two main clades, the vascular plants and the non-vascular bryophytes including hornworts, liverworts and mosses. READ MORE

  6. 4. The role of auxin in abscission of organs and tissues

    Author : Xu Jin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Most deciduous trees drop their leaves before winter, a process which is referred to as leaf abscission. Leaf abscission is thought to be regulated by the action of auxin and ethylene. READ MORE

  7. 5. Characterisation of Members of the HD-Zip I and DREB/ERF Transcription Factor Families and their Functions in Plant Stress Responses

    Author : Elin Övernäs; Peter Engström; Jaako Kangasjärvi; Uppsala universitet; []
    Keywords : Fysiologisk botanik; Physiological Botany;

    Abstract : Plants have to adapt to various environmental conditions. In comparison with other eukaryotes, plant genomes encode relatively many transcription factors, and have families of transcription factors only found in plants, two such are the large AP2/ERF (APETALA2/Ethylene Responsive Factor) and HD-Zip (Homeodomain leucine zipper) families.
