1. 21. Phytostabilization of mine tailings covered with fly ash and sewage sludge

   Författare :Clara Neuschütz; Maria Greger; Lena Kautsky; Anthony R. Dexter; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ammonium; biosolids; cadmium; copper; energy crop; metal and nutrient leakage; nitrate; phosphate; phytoremediation; plant stress response; root exudates; zinc; Plant physiology; Växtfysiologi; växtfysiologi; Plant Physiology;

   Sammanfattning : Establishing plant communities is essential for the restoration of contaminated land. As potential cover materials, fly ash and sewage sludge can prevent formation of acid mine drainage from sulfidic mine waste. LÄS MER

3. 22. Chlorophyll fluorescence as a biological feedback signal -for optimized plant growth conditions and stress diagnosis

   Författare :Linnéa Ahlman; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cucumber; indoor farming; abiotic stress; Fluorescence gain; ESC; biotic stress; basil; dynamics; strawberries; light spectrum; greenhouse lighting control; lettuce; powdery mildew Podosphaera aphanis; Pythium ultimum; LED; classification; lemon balm;

   Sammanfattning : The use of light emitting diodes (LEDs) instead of traditional high pressure sodium lamps, in greenhouses and indoor growing facilities, enables tuning and optimization of both light intensity and light spectrum. This opens for an energy saving potential not possible otherwise. LÄS MER

4. 23. Plant Calreticulins -Calcium-binding proteins with many functions

   Författare :Anna Christensen; Biokemi och Strukturbiologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; tobacco; plant; calreticulin; isoforms; Arabidopsis; localization; mouse embryonic fibroblasts;

   Sammanfattning : Endoplasmic reticulum (ER) plays an important role in protein synthesis, folding, maturation and transport of newly synthesized proteins, as well as the regulation of cellular Ca2+ homeostasis. A protein that is involved in several of these functions in the ER is calreticulin (CRT), which is a Ca2+-binding chaperone that resides in the lumen of the ER. LÄS MER

5. 24. Nucleotide-binding Proteins in the Plant Thylakoid Membrane

   Författare :Sophie Heurtel Thuswaldner; Cornelia Spetea Wiklund; Bengt Persson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plant; Arabidopsis; photosynthesis; thylakoid membrane; nucleotide-binding; Cell and molecular biology; Cell- och molekylärbiologi;

   Sammanfattning : Life on Earth is dependent on the oxygen produced through photosynthesis. The thylakoid membrane is the site for the light-driven reactions of photosynthesis, which oxidize water and supply energy in the form of ATP, mainly for carbon fixation. The utilization of ATP in the lumenal space of the thylakoid has not been considered in the past. LÄS MER

7. 25. Role of cadmium and ultraviolet-B radiation in plants, Influence on photosynthesis and element content in two species of Brassicaceae

   Författare :Helene Larsson Jönsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; UV-B; plant nutrients; photosynthesis; oxygen evolution; chlorophyll fluorescence; Cd uptake; cadmium; Arabidopsis thaliana; Brassica napus; Plant biochemistry; Växtbiokemi; Botany; Botanik;

   Sammanfattning : Plants are exposed to many different stress factors during their lifetime, often more than one factor at a time, which highlights the importance of research regarding interaction among stress factors. Cadmium and ultraviolet-B radiation (UV-B, 280-315 nm) are two potential stress factors in the environment, which have gained increased interest due to atmospheric pollution. LÄS MER
