  1. 1. Gene regulation of UDP-glucose synthesis and metabolism in plants

    Författare :Henrik Johansson; Pierdomenica Perata; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; antisense; Arabidopsis thaliana; carbohydrate; hybrid aspen; photosynthesis; poplar; sugar; UDP-glucose; UDP-glucose pyrophosphorylase; UDP-glucose dehydrogenase; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Photosynthesis captures light from the sun and converts it into carbohydrates, which are utilised by almost all living organisms. The conversion between the different forms of carbohydrates is the basis to form almost all biological molecules. LÄS MER

  3. 2. Characterization of adventitious root formation in Populus species and Norway spruce

    Författare :Sanaria Alallaq; Catherine Bellini; Carmen Diaz-Sala; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Adventitious root; Conifers; Picea abies; auxin; cytokinins; jasmonate; red light; Populus spp.; hybrid poplar; hybrid aspen; cambium; stem cuttings; P. tremula; Swedish Aspen SwAsp collection;

    Sammanfattning : Adventitious root (AR) formation is a form of post-embryonic development and is a key adaptive trait in plants. De novo adventitious root regeneration represents an elegant evolutionary innovation that allows many plant species to multiply through vegetative propagation; it is widely used in forestry and horticulture to multiply elite genotypes.

  4. 3. Functional studies of a membrane-anchored cellulase from poplar

    Författare :Ulla Jonsson Rudsander; Tuula Teeri; Eva Nordberg-Karlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Populus; cellulose biosynthesis; endo-1; 4-b-glucanase; cellulase; Pichia pastoris; Arabidopsis thaliana; NMR spectroscopy; cleavage pattern; stereochemistry; transglycosylation; complementation; hybrid proteins; overexpression; substrate analysis; overglycosylation; Bioengineering; Bioteknik;

    Sammanfattning : Cellulose in particular and wood in general are valuable biomaterials for humanity, and cellulose is now also in the spotlight as a starting material for the production of biofuel. Understanding the processes of wood formation and cellulose biosynthesis could therefore be rewarding, and genomics and proteomics approaches have been initiated to learn more about wood biology.

  5. 4. The significance of ethylene and ETHYLENE RESPONSE FACTORS in wood formation of hybrid aspen

    Författare :Bernard Wessels; Hannele Tuominen; Judith Felten; Totte Niittylä; Kurt Fagerstedt; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ethylene; wood formation; hybrid aspen; Populus; ETHYLENE RESPONSE FACTOR; ERF85; ERF139; cambium; lignin; xylem expansion; secondary cell wall; tension wood; cambial derivative cell fate; vessel element; time-lapse photography; molekylär bioteknik inst f nat vet biokemi ; molecular biotechnology dept of biochem ; genetik; Genetics; Physiological Botany; fysiologisk botanik;

    Sammanfattning : The woody tissues serve to stabilise plants, store nutrients and translocate water and minerals. The formation of wood, or ’secondary xylem’, follows a well-defined developmental gradient which is initiated by cell division activity in the vascular cambium. LÄS MER

  7. 5. Establishment and early management of Populus species in southern Sweden

    Författare :Rebecka Mc Carthy; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Populus species are among the most productive tree species in Sweden. Interest in growing them has increased during the 21st century due to political goals to increase the share of renewable energy and to increase the proportion of hardwood species in forests. LÄS MER
