1. 16. Non-target Effects of Genetically Modified Trees

   Författare :Patrik Blomberg; Anders Wennström; Jan Stenlid; Umeå universitet; []
   Nyckelord :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

3. 17. Understanding and manipulating primary cell walls in plant cell suspension cultures

   Författare :Felicia Leijon; Vincent Bulone; Katja Salomon Johansen; KTH; []
   Nyckelord :Callose synthase; carbohydrate-binding module; cell wall engineering; cellulose microfibril; cellulose nanocrystal; glycosyltransferase; mass spectrometry; plasmodesmata; Populus; primary cell wall; radiometric assay; spectrophotometric assay; Biotechnology; Bioteknologi;

   Sammanfattning : The cell wall is required for many aspects of plant function and development. It is also an accessible and renewable resource utilized both in unrefined forms and as raw material for further development. Increased knowledge regarding cell wall structure and components will contribute to better utilization of plants and the resources they provide. LÄS MER

4. 18. Latent variable based computational methods for applications in life sciences : Analysis and integration of omics data sets

   Författare :Max Bylesjö; Johan Trygg; Tormod Naes; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Chemometrics; orthogonal projections to latent structures; OPLS; O2PLS; K-OPLS; kernel-based; non-linear; regression; classification; Populus; Chemistry; Kemi;

   Sammanfattning : With the increasing availability of high-throughput systems for parallel monitoring of multiple variables, e.g. levels of large numbers of transcripts in functional genomics experiments, massive amounts of data are being collected even from single experiments. LÄS MER

5. 19. The Role of Proteases in Plant Development

   Författare :Maribel Garcia-Lorenzo; Christiane Funk; Zach Adam; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Comparative genomics; protease; PCD; leaf senescence; FtsH; Arabidopsis; Populus; Biochemistry; Biokemi;

   Sammanfattning : Proteases play key roles in plants, maintaining strict protein quality control and degrading specific sets of proteins in response to diverse environmental and developmental stimuli. Similarities and differences between the proteases expressed in different species may give valuable insights into their physiological roles and evolution. LÄS MER

7. 20. Discovery and Characterization of a Novel Microtubule Associated Protein Involved in Cellulose Biosynthesis

   Författare :Alex Selvanayagam Rajangam; Tuula Teeri; Anne-Mie Emons; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MAP; unknown gene; cellulose biosynthesis; Populus; microtubule; DCB; Bioengineering; Bioteknik;

   Sammanfattning : Cell walls are a distinct feature of plants and their chemical constituents, cellulose, hemicelluloses and lignin, are economically valuable. Plant fibres rich in cellulose, which mainly resides in their cell wall, are traditionally used in making paper and textiles. LÄS MER
