   Sammanfattning : The enormous challenge of climate change is discussed and debated today because of its major impact on life on Earth. The forests have an important role to play as the plants absorb carbon dioxide (CO2) from the atmosphere through their photosynthesis and the growing tree retain carbon (C). LÄS MER

5. 4. Genomic studies of mating system variation in flowering plants

   Författare :Juanita Gutiérrez-Valencia; Tanja Slotte; Magne Friberg; Mario Vallejo-Marín; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mating system evolution; cross- and self-fertilization; distyly; supergenes; complex phenotypic polymorphism; convergent evolution; homostyly; loss-of-function mutation; intrasexual competition; pollen; purifying selection; Linum; Arabis alpina; Ecology and Evolution; ekologi och evolution;

   Sammanfattning : The striking diversity of reproductive strategies that flowering plants exhibit remains one of the most intriguing conundrums in evolutionary biology. Pollination-related traits and mating system strategies have a major impact on the processes shaping plant evolution through their effects on genetic diversity and selection. LÄS MER

7. 5. NMR studies of metabolites and xenobiotics : From time-points to long-term metabolic regulation

   Författare :Ina Ehlers; Jürgen Schleucher; Farquhar Graham; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; isotopomer; phospholipid; persistent organic pollutant; CO2 fertilization; photorespiration;

   Sammanfattning : Chemical species carry information in two dimensions, in their concentrations and their isotopic signatures. The concentrations of metabolites or synthetic compounds describe the composition of a chemical or biological system, while isotopic signatures describe processes in the system by their reaction pathways, regulation, and responses to external stimuli.
