  1. 1. How could Christmas trees remain evergreen? : photosynthetic acclimation of Scots pine and Norway spruce needles during winter

    Author : Pushan Bag; Stefan Jansson; Fransis Andre Wollman; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Scots Pine; Norway spruce; Photosynthesis; Winter adaptation; biologisk kemi; biological chemistry; biology; biologi; molekylärbiologi; Molecular Biology; Physiological Botany; fysiologisk botanik;

    Abstract : Plants and other green organisms harvest sunlight by green chlorophyll pigments and covertit to chemical energy (sugars) and oxygen in a process called photosynthesis providing the foundation for life on Earth. Although it is unanimously believed that oceanic phytoplanktons are the main contributors to the global photosynthesis, the contribution of coniferous boreal forests distributed across vast regions of the northern hemisphere cannot be undermined.

    Abstract : Our societies' wellbeing relies on stable and healthy environments. However, our current lifestyles, growth-oriented economic policies and the population explosion are leading to potentially catastrophic degradation of ecosystems and progressive disruption of food chains. READ MORE

  3. 3. Development of molecular techniques for fungal diagnostic research

    Author : Qing-Yin Zeng; Åsa Rasmuson-Lestander; Xiao-Ru Wang; Aino Nevalainen; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Fungi; DNA markers; Aerosols; Detection and quantification; Environmental monitoring; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Abstract : Fungi are present everywhere in indoor and outdoor environments. Many fungi are toxigenic or pathogenic that may cause various public health concerns. Rapid detection, quantification and characterization of fungi in living and working environments are essential for exposure risk assessment to safe guard public health. READ MORE

  4. 4. A systems biology understanding of protein constraints in the metabolism of budding yeasts

    Author : Iván Domenzain Del Castillo Cerecer; Chalmers tekniska högskola; []

    Abstract : Fermentation technologies, such as bread making and production of alcoholic beverages, have been crucial for development of humanity throughout history. Saccharomyces cerevisiae provides a natural platform for this, due to its capability to transform sugars into ethanol. READ MORE

  5. 5. The circadian clock in annuals and perennials : coordination of Growth with Environmental Rhythms

    Author : Mikael Johansson; Maria E. Eriksson; Paul Devlin; Umeå universitet; []
