  1. 1. Plant UDP-glucose Pyrophosphorylase : Function and Regulation

    Författare :Meng Meng; Leszek Kleczkowski; Javier Pozueta-Romero; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; UDP-glucose pyrophosphorylase; carbohydrate metabolism; in vivo regulation; T-DNA knockout; heterologous expression; isozyme; mutagenesis; kinetic property; oligomerization; Plant physiology; Växtfysiologi;

    Sammanfattning : UDP-glucose pyrophosphorylase (UGPase) is an important enzyme of carbohydrate metabolism in all living organisms. The main aim of this thesis was to investigate the function and regulation of plant UGP genes as well as the UGPase proteins. LÄS MER

  2. 2. Metabolic engineering of starch synthesis in barley

    Författare :Staffan Ahlandsberg; Sadequr Rahman; Australien Canberra CSIRO Plant Industry; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; hordeum vulgare; plant breeding; starch; genetic engineering; transgenic plants; biokemi; Biochemistry;

    Sammanfattning : Starch is an important industrial raw material both for food and non-food purposes. In plants, starch is deposited in the leaf and in the storage tissues such as seed endosperm, roots or tubers. LÄS MER

  3. 3. Genetic Control of Annual Growth Rhythm in the Conifer Norway Spruce (Picea Abies L. Karst)

    Författare :Anna Karlgren; Ulf Lagercrantz; Niclas Gyllenstrand; Janice Cooke; Uppsala universitet; []
    Nyckelord :AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; LANTBRUKSVETENSKAPER; NATURAL SCIENCES; AGRICULTURAL SCIENCES; bud set; circadian clock; Picea abies; growth cessation; phosphatidyl ethanolamine-binding protein PEBP genes; Biologi med inriktning mot evolutionär funktionsgenomik; Biology with specialization in Evolutionary Functional Genomics;

    Sammanfattning : Norway spruce (Picea abies L. Karst) is a conifer belonging to the group gymnosperms and is an ecologically and economically important species in several parts of Europe. LÄS MER

  4. 4. Non-target Effects of Genetically Modified Trees

    Författare :Patrik Blomberg; Anders Wennström; Jan Stenlid; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Genetically modified; GM trees; secondary metabolism; phytochemistry; Populus; transgenic; non-target effects; natural enemies; plant-pathogen herbivore interaction; environmental effects; parasitic fungi; herbivorous insect; Terrestrial ecology; Terrestisk ekologi;

    Sammanfattning : To date, few studies have focused on the effects of genetically modified trees (GM trees) on the environment. One concern with GM trees is that they may have unanticipated effects on non-target organisms, i.e. effects on organisms that are not direct targets of the genetically modified trait. LÄS MER

  5. 5. The light-harvesting antenna of higher plant photosystem I

    Författare :Ulrika Ganeteg; Umeå universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Plant physiology; antisense; Arabidopsis thaliana; chlorophyll; fitness; LHC; photosynthesis; Växtfysiologi; Plant physiology; Växtfysiologi;

    Sammanfattning : During photosynthesis, two multi-protein complexes, photosystems (PS) I and II work in tandem to convert the light-energy absorbed by the light-harvesting antennae into chemical energy, which is subsequently used to assimilate atmospheric carbon dioxide into organic carbon compounds. This is the main nutritional basis for life on Earth. LÄS MER
