  1. 1. Cold Acclimation : Dissecting the plant low temperature signaling pathway using functional genomics

    Författare :Catherine Benedict; Vaughan Hurry; Matsuo Uemura; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cold acclimation; functional genomics; microarray; Populus tremula; Arabidopsis thaliana; gene voting; regulon; enhancer-blocking; Plant physiology; Växtfysiologi;

    Sammanfattning : The physiological process of cold acclimation protects plants native to the temperate regions of the world from the deleterious effects of low and freezing temperatures. This is achieved by a series of transcriptional, regulatory, and metabolic changes that enable continued growth and survival. Within minutes of exposure to temperatures below ca. LÄS MER

  3. 2. Low temperature acclimation in plants : alterations in photosynthetic carbon metabolism

    Författare :Maria Lundmark; Vaughan Hurry; Charles Guy; Umeå universitet; []
    Nyckelord :Plant physiology; cold acclimation; carbon metabolism; photosynthesis; respiration; Växtfysiologi; Physiological Botany; fysiologisk botanik;

    Sammanfattning : Although low temperature plays an important role in determining agricultural yield, little is known about the effect on the underlying biochemical and physiological processes that influence plant growth. Photosynthesis and respiration are central to plant growth and both processes are heavily affected by temperature. LÄS MER

  4. 3. Acclimation of boreal Norway spruce to climate change: Empirical and modelling approaches

    Författare :Shubhangi Lamba; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Norway spruce; Climate change; Acclimation; MAESTRA; Whole Tree Chamber;

    Sammanfattning : The findings of this thesis have important implications for the projections of future carbon and water fluxes for the boreal region. The observed boreal longterm acclimation responses of respiration and stomatal regulation differ from those of most temperate regions. LÄS MER

  5. 4. Unravelling the complexity of cold acclimation in plants

    Författare :Aakash Chawade; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; bioinformatics; cold acclimation; winter; oat; arabidopsis; stress; freezing; genetic networks; metabolomics;

    Sammanfattning : Many plants respond to low non-freezing temperatures by increasing their freezing tolerance in a process known as cold acclimation. Microarray studies have shown that hundreds of genes are differentially expressed during the cold acclimation process in Arabidopsis. LÄS MER

  7. 5. Acclimation of plants to combinations of abiotic factors : connecting the lab to the field

    Författare :Zsofia Réka Stangl; Vaughan Hurry; Lisa Ainsworth; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; nitrogen; carbon dioxide; temperature; thermal acclimation; mycorrhiza; boreal forest; climate change; C:N balance; allocation; respiration; photosynthesis; terrestrial biosphere model;

    Sammanfattning : Increasing atmospheric CO2 and other greenhouse gasses coupled to the accelerated rate of global warming puts plants and ecosystems under the strain of a rapidly changing abiotic environment. Understanding the impacts of changing global climate is a strong focus of plant science and the establishment of more resilient crop variants is an important goal for breeding programs. LÄS MER
