2. 1. Functional studies of a membrane-anchored cellulase from poplar

   Author : Ulla Jonsson Rudsander; Tuula Teeri; Eva Nordberg-Karlsson; KTH; []
   Keywords : 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;

   Abstract : 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.

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

   Author : Sanaria Alallaq; Catherine Bellini; Carmen Diaz-Sala; Umeå universitet; []
   Keywords : 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;

   Abstract : 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.

5. 3. Integration of Arabidopsis and poplar model systems to elucidate gene function during wood formation

   Author : Ellinor Edvardsson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : Wood is an essential raw material being used for a number of different applications including construction, pulp and paper production and as a source of biomass for bioenergy generation. The increasing number of sequenced plant genomes provides powerful tools to evaluate plant gene function. READ MORE

6. 4. Gene finding in Populus- The Bioinformatics of a EST program

   Author : Rupali Bhalerao; KTH; []
   Keywords : ;

   Abstract : During the course of the work described in this thesis, ESTsequencing project was initiated in woody plant poplar forlarge scale gene discovery in a tree specie. Since most of thetree genomes are considerably large in size, EST sequencing wasconsidered to be a cost effective method for gene discovery. READ MORE

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

   Author : Rebecka Mc Carthy; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

   Abstract : 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. READ MORE
