1. 1. Sugar-modulated gene expression and cell division in cell culture and seedlings of A. thaliana

   Författare :Sabine Kunz; Leszek A. Kleczkowski; Alison Smith; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; carbohydrates; cell culture; cell division; gene expression; homeostasis; live cell imaging; sugar-signals; sugar-analogues; Physiological Botany; fysiologisk botanik;

   Sammanfattning : Throughout their life cycle, plants adjust growth in response to their developmental and environmental situation within the limits of their energetic capacities. This capacity is defined by the local sugar availability, which is constantly modulated through synthesis, transport and consumption of sugar. LÄS MER

3. 2. From green to yellow : a leaf story

   Författare :Olivier Keech; Per Gardeström; Pierre Dizengremel; Lee Sweetlove; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; chloroplasts; cytoskeleton; darkness; metabolism; microscopy; mitochondria; microtubules; senescence; system redox; Plant physiology; Växtfysiologi;

   Sammanfattning : När ett blad gulnar genomgår det både morfologiska och metaboliska förändringar. Denna process benämns senescence och en förbättrad förståelse av dess mekanismer är viktiga både ur ett grundvetenskapligt perspektiv och för potentiella bioteknologiska applikationer. LÄS MER

4. 3. Sequence evolution in a chromosomal region of Arabidopsis thaliana

   Författare :Jenny Hagenblad; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtgenetik; Plant genetics; flowering time; mapping; polymorphism; Linkage disequilibrium; Arabidopsis thaliana;

   Sammanfattning : Recently there has been a lot of interest in the use of liknage disequilibrium (LD) in genome wide scans for new genes, so called association mapping. Of crucial importance to a genome wide scan for associations between genetic markers and the trait of interest is the extent of LD, as it determines both how closely a trait can be mapped and also how many markers is needed to map it.

5. 4. Meristem Maintenance in Arabidopsis thaliana

   Författare :Alessia Para; Annika Sundås Larsson; Jan Traas; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Life sciences and physical sciences; Arabidopsis thaliana; development; shoot apical meristem; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP;

   Sammanfattning : The shoot apical meristem (SAM) is the structure that shapes the aerial architecture of the plant, by producing lateral organs throughout development. In the model plant Arabidopsis thaliana, the SAM is always identifiable as a characteristic dome, whether it is found in the centre of a rosette of leaves or at the tip of an inflorescence. LÄS MER

7. 5. Genome Divergence in Progress - a population genetic analysis of the allopolyploid Arabidopsis suecica and its maternal parent A. thaliana

   Författare :Mattias Jakobsson; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cytogenetik; Genetik; cytogenetics; Genetics; sequence polymorphism; microsatellites; population structure; polyploidy; single origin; Arabidopsis thaliana; Arabidopsis suecica; genome evolution; evolutionary history; Plant genetics; Växtgenetik;

   Sammanfattning : The evolutionary history of the allotetraploid Arabidopsis suecica and its maternal parent Arabidopsis thaliana is analyzed in the thesis in terms of genetic variation in the natural populations of the two species. The earliest phase of the speciation event in which the genomes of A. thaliana and A. LÄS MER
