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

    Författare :Mikael Johansson; Maria E. Eriksson; Paul Devlin; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; circadian clock; arabidopsis; populus; Molecular biology; Molekylärbiologi; Plant biotechnology; Växtbioteknik; Plant physiology; Växtfysiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Since the first signs of life on planet earth, organisms have had to adapt to the daily changes between light and dark, and high and low temperatures. This has led to the evolution of an endogenous time keeper, known as the circadian clock. LÄS MER

  3. 7. Herbivores influence nutrient cycling and plant nutrient uptake : insights from tundra ecosystems

    Författare :Hélène Barthelemy; Olofsson Johan; Ellen Dorrepaal; Ann Milbau; Gough Laura; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Reindeer grazing; large herbivores; nutrient cycling; plant nutrient uptake; soil nutrient availability; arctic plant ecology; soil microbial communities; 15N stable isotopes; plant-soil interactions; plant quality; dung and urine.; Environmental Science; miljövetenskap; biology; biologi;

    Sammanfattning : Reindeer appear to have strong positive effects on plant productivity and nutrient cycling in strongly nutrient-limited ecosystems. While the direct effects of grazing on vegetation composition have been intensively studied, much less is known about the indirect effect of grazing on plant-soil interactions. LÄS MER

  4. 8. Plant cell-inspiredmicrocontainers: Fabrication, Characterization and Applications

    Författare :Thomas Paulraj; Anna Justina Svagan; Daniel Crespy; KTH; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Biomimetic materials have been inspiring mankind since a longtime for applications in a variety of fields. In particular, the production of lipidbasedvesicles have aided in our understanding of a variety of functions in animalcells, and also served as e.g. drug delivery systems and bioreactors. LÄS MER

  5. 9. Setosphaeria turcica, fungal mating and plant defence

    Författare :Thomas Martin; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The heterothallic ascomycete Setosphaeria turcica (anamorph: Exserohlium turcicum) causes turcicum leaf blight on maize and sorghum. A survey was undertaken in Uganda to examine the sorghum – S. turcica interaction in terms of disease severity and incidence, overall fungal population structure, and new resistant resources.

  7. 10. Plant Aquaporins: A study of expression, localization, specificity, and regulation

    Författare :Sara Sjövall Larsen; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtbiokemi; Plant biochemistry; phosphorylation; protein kinase; overexpression; NIP; MIP; plant; aquaporin;

    Sammanfattning : Aquaporins, or Major Intrinsic Proteins (MIPs), are integral proteins that facilitate transport of water and other small neutral solutes across biological membranes. They belong to a well conserved and ancient family of proteins, present in all organisms ranging from bacteria to plants and humans. LÄS MER
