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. 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

4. 3. Cold Acclimation in oats and other plants: Dissecting low temperature responses using a comparative genomic approach

   Författare :Marcus Bräutigam; Göteborgs universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cold acclimation; oat; EST; microarray; transcriptome; chilling; freezing; rice; Arabidopsis; TILLING; mutation;

   Sammanfattning : Cold acclimation protects plants from temperate regions of the world from the deleterious effects of low and freezing temperatures. This is through a series of transcriptional, regulatory and metabolic changes that enable continued growth and survival. LÄS MER

5. 4. Physiological and biochemical aspects of vegetable processing. A case study on carrots

   Författare :Federico Gómez Galindo; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; mild blanching; antifreeze proteins; cell wall; cold acclimation; carrots; metabolism;

   Sammanfattning : The aim of the present study was to enhance our understanding of vegetables as living organisms, interacting dynamically with the environment, and to explore the possible influence of metabolic changes on subsequent processing operations. Growing conditions, harvesting and handling in the packing house and storage conditions are key events leading to a defined “physiological status” of the vegetable that is going to be consumed as a fresh product or a processed product.

7. 5. Natural variation in cold adaptation and freezing tolerance in Arabidopsis thaliana

   Författare :Antoine Bos; Pär Ingvarsson; Hans Stenøien; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; cold acclimation; freezing tolerance; flowering time; latitudinal clines; genetic variation; evolutionary genetics; Molecular biology; Molekylärbiologi;

   Sammanfattning : Plants have spread to almost everywhere in the world. As they disperse, they meet many different environments to which they may be able to adapt. For a plant species to adapt to a new environment, genetic variation is needed. The individuals differ from each other in their genetic composition, which often means differences in phenotypes.
