    Sammanfattning : The genus Arnica (Asteraceae) was investigated for phylogenetic relationships and sesquiterpene lactone (STL) content with the aims to trace the evolutionary history of the genus and to investigate possible congruencies between DNA sequence data, secondary chemistry, and biological activity. Complex evolutionary patterns in Arnica are evident from phylogenetic analyses of chloroplast regions (the rpl16 and rps16 introns and the psbA–trnH, ycf4–cemA, and trnT–L spacers), nuclear ribosomal regions (the internal and external transcribed spacers) and the nuclear low-copy DNA region coding for the second largest subunit of RNA polymerase II (RPB2) between exons 17 and 23.

  3. 17. Steady, ready, go - proteomics of etioplast inner membranes reveals a high readiness for light

    Författare :Lisa A. Blomqvist; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chloroplast; etioplast; NADPH:protochlorophyllide oxidoreductase; prolamellar body; proteomics; prothylakoid; transmembrane; Triticum aestivum; wheat;

    Sammanfattning : Light is essential for development of photosynthetically active chloroplasts. In the absence of light proplastids develop into etioplasts which are readily transformed into chloroplasts upon illuminat... LÄS MER

  4. 18. Molecular Mechanisms Optimizing Photosynthesis during High Light Stress in Plants

    Författare :Lan Yin; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis; light stress; photosynthesis; chloroplast;

    Sammanfattning : Oxygenic photosynthesis is the process by which plants, algae and cyanobacteria use solar energy to convert water and carbon dioxide into molecular oxygen and carbohydrates. Photosynthesis sustains life on Earth since it provides not only energy for individual growth, but also represents the starting point of the food chain for most living organisms. LÄS MER
