  1. 16. The molecular mechanisms behind perception and signal transduction of UV-B irradiation in Arabidopsis thaliana

    Författare :Irina Kalbina; Åke Strid; Lars-Gunnar Franzén; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Action spectroscopy; Arabidopsis; gene expression; reverse genetics; signal transduction; UV-B irradiation.; Biochemistry; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : Elevation of UV-B radiation (280-315 nm), occurring as a result of depletion of the stratospheric ozone, causes a number of physiological and biochemical changes in plants. Damage to the photosynthetic apparatus (including the bleaching of the pigments which trap the sun's energy), to the processes of cell division and growth regulation, and to the composition and replication of genetic material are just some of these changes.

  3. 17. 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

  4. 18. HDZip I Transcription Factors in Arabidopsis thaliana : Expression and Function in Relation to Environmental Stress Conditions

    Författare :Anna S. B. Olsson; Peter Engström; Eva Söderman; Pieter B. F. Ouwerkerk; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biology; homeodomain leucine zipper; ABA; transcription factor; water deficit; Arabidopsis thaliana; Biologi; Biology; Biologi;

    Sammanfattning : The homeodomain leucine zipper (HDZip) proteins constitute a plant-specific family of transcription factors, that based on sequence criteria have been grouped into four classes, HDZip I-IV. This thesis describes the phylogeny, function, expression patterns and regulation of the HDZip class I genes in the model species Arabidopsis thaliana. LÄS MER

  7. 20. Analysis of Two Transcriptional Regulators that Affect Meristem Function : Arabidopsis thaliana TERMINAL FLOWER2 and Picea abies APETELA2

    Författare :Lars Nilsson; Annika Sundås Larsson; Peter Engström; Thomas Laux; Uppsala universitet; []
    Nyckelord :Developmental biology; Arabidopsis thaliana; Picea abies; gene regulation; development; meristem; Utvecklingsbiologi;

    Sammanfattning : The aerial plant body is derived from undifferentiated cells in the shoot apical meristem that in Arabidopsis thaliana is active throughout the plant life cycle. Upon transition to flowering the activity of the meristem is altered and the meristem starts to produce secondary inflorescences and floral meristems instead of leaves. LÄS MER
