  2. 1. Haustoria regulation in the facultative parasitic plant Phtheirospermum japonicum

    Author : Anna Kokla; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Parasitic plants are important agricultural pests that lead to considerable yield losses annually. Parasitic plants that completely rely on their hosts for their survival are known as obligatory parasites, whereas those independent of their hosts but parasitize under the right conditions are known as facultative parasitic plants.

  4. 2. The immunomodulatory properties of C-Med 100 an extract of the plant Uncaria tomentosa

    Author : Christina Silver; Diabetes - immunovirologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; Immunologi; serologi; serology; Immunology; survival; proliferation; inhibition; NF-kB; Uncaria tomentosa; quinic acid;

    Abstract : Extracts from the bark of the vine Uncaria tomentosa have anti-inflammatory, antiviral, antimutagenic and antioxidant effects. In this study, we evaluate the effects of an Uncaria tomentosa extract, denoted C-Med 100, on the cellular level of the immune system both in vivo and in vitro. READ MORE

  5. 3. Mechanism of Action of the Plant Growth Promoting Bacterium Paenibacillus polymyxa

    Author : Salme Timmusk; Gerhart Wagner; Janet Jansson; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbiology; Plant growth promotion; Induced resistance; Biocontrol; Deleterious rhizobacterium; Mikrobiologi; Microbiology; Mikrobiologi;

    Abstract : Paenibacillus polymyxa belongs to the group of plant growth promoting rhizobacteria (PGPR). Activities associated with P. polymyxa-treatment of plants in earlier experiments include, e.g. READ MORE

  6. 4. Effects of Pulsed Electric Fields on Plant Tissue

    Author : Yongyut Chalermchat; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Electropermeabilization; Pulsed electric fields; Plant Tissue; Teknik;

    Abstract : The interaction between biological cells and external electric fields has been of interest by scientists for several decades. Exposure of the cells to electric fields leads to various kinds of biophysical and biochemical responses. These responses can be used to characterize cell properties and/or to manipulate cell characteristics. READ MORE

  7. 5. 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
