1. 1. Control of reactive oxygen species homeostasis in response to environmental stress

   Författare :Malgorzata Plaszczyca; Katharina Pawlowski; Jean-Jacques Drevon; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stress; antioxidant defense; ascorbate peroxidase; aerenchyma; actinorhiza; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

   Sammanfattning : Plants are exposed to various fluctuations in their environmental conditions - light intensity, temperature, water status - and have to adapt in order to survive. Plant acclimatory responses can include the formation of new tissues, e.g., aerenchyma, or the activation of defense systems, e. LÄS MER

3. 2. Seagrass productivity : from plant to system

   Författare :Diana Deyanova; Mats Björk; Mirta Teichberg; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Seagrass; Chlorophyll a fluorescence; Ageing; Productivity; Seasonality; Stress response; Plant Physiology; växtfysiologi;

   Sammanfattning : Seagrasses form one of the most productive habitats on earth and are recognized as very efficient carbon sinks. The levels and patterns of productivity within and across different seagrass systems vary widely due to natural or human-induced factors. LÄS MER

4. 3. Coordination of two different genomes in response to light and stress

   Författare :Louise Norén Lindbäck; Åsa Strand; Antony Dodd; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplast; cellular communication; tetrapyrrole; circadian clock; oxidative stress; light signalling; gene regulation; molekylärbiologi; Molecular Biology;

   Sammanfattning : About 1.5 billion years ago, a photosynthetic bacteria was engulfed by a eukaryotic cell which initiated a symbiotic relationship and the evolution of the chloroplast as we know it today. The chloroplast has retained its own genome encoding for a number of proteins required for the function of the chloroplast. LÄS MER

5. 4. Biotic and abiotic stress in microorganisms and plants: Some Mechanisms of Stress and Programmed Cell Death. Genetic Engineering Approaches Towards Improved Stress Tolerance

   Författare :Per-Johan Meijer; Tillämpad biokemi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biotic stress; plants; microorganisms; stress tolerance; antifreeze protein; proline; programmed cell death; systemic aquired resistance; Biochemistry; metabolism; Biokemi; Bioteknik; Biotechnology; abiotic stress;

   Sammanfattning : Various forms of stress, such as biotic and abiotic stress, were studied in microorganisms and plants to learn more about the underlying mechanisms of such stress and potential genetic engineering strategies towards stress tolerance. An antifreeze protein from winter flounder, expressed in E. LÄS MER

7. 5. Stress-induced BVOC emissions from forests in Sweden

   Författare :Erica Jaakkola; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Volatile organic compounds; Plant stress; Forests; Volatile emissions; spruce bark beetle infestations; ozone stress; wildfire recovery; Picea abies Norway spruce ; Betula pubescens ssp. czerepanovii; Pinus sylvestris Scots pine ; sweden;

   Sammanfattning : A changing climate is expected to lead to more extreme weather events, such as an increased frequency of droughts and forest fires. Changing forest conditions can offer benefits to species such as insects, including bark borers that thrive in warm conditions. LÄS MER
