  2. 21. The effect of stress on plant vascular development and regeneration

    Author : Shamik Mazumdar; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Plants are susceptible to stress due to their lifestyle and as such have evolved multiple adaptive strategies to ensure survival. One of the most remarkable abilities in plants is their competence to regenerate tissues. Particularly, any damage to vascular tissues is healed quickly to continue survival. READ MORE

  4. 22. Strategic nitrogen management in stockless organic cropping systems : redistribution of residual biomass for improved energy and nitrogen balance

    Author : Tora Råberg; Sweden SLU; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; bioenergy; biomass management; crop rotation; ecological intensification; green manure; life cycle assessment; nitrogen cycling; organic agriculture; soil incubation; stockless cropping systems;

    Abstract : Agriculture faces the challenge of producing high yields to feed a growing world population, while simultaneously addressing environmental problems such as eutrophication, emissions of greenhouse gases, loss of biodiversity and soil degradation. Organic farming can be part of the solution, as it promotes biodiversity, uses less energy for fertiliser production and often has higher inputs of organic matter to soil than conventional farming.

  6. 24. Novel insights into vacuole-mediated control of plant growth and immunity

    Author : Qinsong Liu; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Plant vacuoles are organelles with numerous biological functions in growth, development, and stress responses. These include maintenance of turgor pressure, storage of minerals and proteins, and degradation of cellular content delivered by endosomal trafficking and autophagy pathways. READ MORE

  7. 25. Multiplier Sequences for Laguerre bases

    Author : Elin Ottergren; Petter Brändén; Björn Gustafsson; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stability preserving operator; orthogonal polynomials; multiplier sequences; Mathematics; matematik;

    Abstract : Pólya and Schur completely characterized all real-rootedness preserving linear operators acting on the standard monomial basis in their famous work from 1914. The corresponding eigenvalues are from then on known as multiplier sequences. READ MORE
